Release Notes

2023

1.16.1 - 2023-aug-30

Anti-cheat
  • Bug fix: Fixed an issue with the Easy Anti-Cheat (EAC) service setup that resulted in launch error 20006 on Windows operating systems.
Auth
  • Bug fix: Fixed the expiration of auth tokens after the application is suspended and then resumed for over 2 hours. This included Epic Account ID auth tokens and the Connect auth refresh notification not firing from EOS_Connect_AddNotifyAuthExpiration.
Connect
  • Bug fix: Fixed the expiration of auth tokens after the application is suspended and then resumed for over 2 hours. This included Epic Account ID auth tokens and the Connect auth refresh notification not firing from EOS_Connect_AddNotifyAuthExpiration.
Lobbies
  • Bug fix: Fixed Lobby connection timeouts after the application is suspended and then resumed.
Mobile
  • Bug fix: We have added the correct Gradle files to the Android login sample, and Android headers are now in the new /SDK/Include directory that matches other platforms.
Sony PlayStation
  • Bug fix: Improved performance of EOS_P2P_SendPacket in high latency situations when targeting PS5 7.00. This bug was introduced in EOS SDK version 1.16.

KNOWN ISSUES AND WORKAROUNDS

Lobbies

  • In EOS SDK version 1.16, if you add an attribute to a lobby using EOS_LobbyModification_AddAttribute without modifying any lobby owner member attributes, the lobby owner member attributes set previously with EOS_LobbyModification_AddMemberAttribute are removed. To address this issue, you must modify, add or remove a member attribute for the lobby owner any time a lobby attribute is modified.

    The attribute value can be anything, as it only matters that one of the member attributes for the lobby owner is changed. You must modify, add or remove the lobby owner attribute as part of the lobby update modification used to change the lobby attribute.

    Example code:

1.16 - 2023-aug-16

Anti-cheat
  • New: The maximum individual message chunk size sent from the server to clients is increased to 512 bytes from 256 bytes.
  • New: We removed a recommendation of what value to use for AuthenticationTimeout in the EOS_AntiCheatClient_RegisterPeerOptions. We no longer recommend a specific timeout value because authentication timeouts are game-specific.
  • New: Updated the anti-cheat LogPlayerTakeDamage API. Now the AttackerPlayer information fields are optional when DamageSource is either NonPlayerCharacter or World.
  • New: The anti-cheat service now logs if it is not configured for your game. This is only for games running on a platform that supports anti-cheat. We removed anti-cheat service output logs which warned that anti-cheat is not configured for your game on platforms which do not support anti-cheat.
  • New: Anti-cheat network message sizes are now logged at VeryVerbose logging level instead of Verbose.
  • New: The anti-cheat integrity tool now logs specific errors more explicitly, for example, that it’s trying to generate an empty catalog.
  • Bug fix: Fixed an incorrect translation for the Thai language when your game launches through EOS EAC bootstrapper.
  • Bug fix: Fixed a bug where the player tracking interface would fail to send most, or all, player information under stable network conditions.
  • Bug fix: Fixed a bug where anti-cheat module updates fail to download if their file size is large.
Authentication
  • New: Added a EOS_LF_NO_USER_INTERFACE input flag for EOS_Auth_Login API. You can use this flag to attempt automatic player login that silently fails without prompting the player.
  • New: Added command-line arguments to the Developer Authentication Tool (Dev Auth Tool):
    • --port=N (where N is the port number): Use this to automatically select the listening HTTP port you want the Dev Auth Tool to use.
    • --credential-name=S (where S is your credentials name): Use this to automatically provide your credentials name when you sign in for the first time.
  • Bug fix: Fixed an edge case crash during authentication with an HTTP retry response.
  • Bug fix: We fixed a potential crash during authentication, which could occur moments before a device authorization expires.
  • Bug fix: We fixed an issue so all external accounts are now included regardless of whether or not the account ID is set. Previously, the external accounts for a user (EOS_UserInfo_ExternalUserInfo) did not include external accounts that existed with an unset account ID. This was unexpected because the account ID is not guaranteed to be available for all users across all external accounts.
Connect
  • New: Added an input parameter, NSAIdToken, so that you can provide an NSA (Nintendo Service Account) ID token for a local user (player) with EOS_Connect_Login. The token is a check to see if the local user has permission to play online. If the local user has a token, the EOS service allows the local user to use the Lobbies Interface and Sessions Interface. If they do not have a token, they can't play online or use either the Lobbies Interface or Sessions Interface.
Console Specific
Sony PlayStation
  • New: Optimized PlayStation 4 build flags to reduce a game's memory footprint.
  • Bug fix: Fixed an issue where bad memory usage, when internally accessing parental controls on PlayStation 4, caused the SDK to crash.
Nintendo Switch
  • New: We updated the Nintendo Switch compilation and link optimizations to compress and reduce binary size. We now use -flto=full and have changed -Os to -Oz (aggressive size).
Crossplay
Ecom

  • New: EOS_Ecom_Checkout returns EOS_Ecom_PurchaseProcessing under the following conditions:

    • The player closes the purchase flow UI after they have confirmed their purchase.
    • The purchase checkout website has not yet returned the transaction ID.

    EOS_Ecom_Checkout previously returned EOS_Canceled.

  • New: Added a new API, EOS_Ecom_QueryOwnershipBySandboxIds, to request ownership by sandbox id. Developers can now use the EOS_Ecom_QueryOwnershipBySandboxIds API to query all owned items for a given set of sandbox IDs.

  • New: The EOS_Ecom_QueryOwnership method can now accept a maximum of 400 catalog Ids in a single API call. The API is also improved to send multiple batched requests to the backend and aggregate the responses.

  • New: The EOS_Ecom_QueryEntitlements method can now accept a maximum of 256 entitlements in a single API call. The API is also improved to send multiple batched requests to the backend and aggregate the responses.

  • Bug fix: Fixed an intermittent issue where EOS_Ecom_RedeemEntitlements failed.

EOS Core

  • New: Added additional logging to functions in the API in C when the invalid parameters, that are null or empty, are passed in.

  • New: eos_init.h now includes definitions for the maximum length of the strings which are your game's:

    • ProductName
    • ProductVersion

    The SDK checks the length of the strings at game startup and fails if they exceed the maximum length.

  • New: eos_types.h now includes definitions for the maximum length of the strings which are your game's:

    • ClientId
    • ClientSecret
    • ProductId
    • SandboxId
    • DeploymentId
    • EncryptionKey

    The SDK checks the length of the strings at game startup and fails if they exceed the maximum length.

  • New: You can now specify how the SDK handles RTC rooms when the application switches between background and foreground states by using the BackgroundMode field of EOS_Platform_RTCOptions.

  • New: Steamworks Support:

    • Added support for Steamworks version 1.13 and higher.
    • Steam sanitization calls only happen if you use Steamworks version 1.45 or higher.
    • Reading the launch command line (for accepting Steam game invites) only works on Steamworks version 1.43 or higher.

  • Bug fix: Fixed an issue where using the wrong type specifiers in the log output would cause the SDK to crash.

  • Bug fix: Fixed an exception that can occur if EOS_Initialization fails.

  • Bug fix: Added additional state checks in the WebSocket destructor before it closes the WebSocket connection in WinHttp. This prevents false warnings about closing sockets when the connection shuts down.

  • Bug fix: Fixed an SDK crash at shutdown if the debugger is attached.

  • Bug fix: Fixed an intermittent issue where peer-to-peer connections fail under the following conditions:

    • Connections start immediately after players sign in.
    • The relay control setting is EOS_RC_ForceRelays.

  • Bug fix: Fixed an issue so EOS_Platform_CheckForLauncherAndRestart now correctly detects if the game was launched by the Epic Games Launcher. See Platform Interface: Restarting the App with the Launcher.

  • Bug fix: Fixed an issue where tasks waiting on results from the configuration service would stall for more than five minutes in cases where the SDK is unable to contact the backend configuration service. This behavior has been modified to ensure that these tasks now retry for less than a minute after which point they are canceled; any dependent tasks are now notified of this cancellation.

  • Bug fix: Fixed a comment in eos_types.h for EOS_Platform_Options::IntegratedPlatformOptionsContainerHandle to correctly describe the behavior when null.

  • Bug fix: Fixed an issue where some internal HTTP requests were misconfigured, and could take much longer to retry than intended. The affected delegates now report connection related issues results much sooner.

EOS SDK in C#
  • Bug fix: Fixed an issue that occurred when you pinned the same buffer multiple times in a multi-threaded environment while using the C# wrapper.
    • For instance, if you used the NetProtect network packet protection feature of the anti-cheat server and decrypting the data in-place, this would cause a crash.
EOS Overlay
  • Bug fix: Fixed intermittent issues that would cause a crash when signing in with a proxy account.
Friends
Lobbies
Mobile
iOS
  • New: Updated the Login Sample UI / UX to reflect recent Android UI / UX updates. The update also includes minor refactoring for clarity and better support of the new UX.
  • Bug fix: Fixed an issue for calls to EOS on multiple threads in the Login Sample on iOS with a dedicated background thread.
Peer-to-peer
  • New: EOS_P2P_SendPacket allows players to send data to themselves locally without sending the data over a network. Packets sent this way are immediately added to the player's local received packet queue and you can retrieve these using the EOS_P2P_ReceivePacket function.
  • Bug fix: Improved packet sending throughput under poor network conditions.
  • Bug fix: Fixed an issue where peer-to-peer fails to fetch new relay server credentials after returning from application or game suspension.
  • Bug fix: Fixed an intermittent race condition issue where a connection fails if two peers attempt to connect to each other at the same time.
  • Bug fix: Fixed peer-to-peer packets being receivable before the SDK fires the ConnectionEstablished peer-to-peer event. Packets are now held until the ConnectionEstablished event happens for the connection.
  • Bug fix: Fixed an issue where a player disconnecting for a short period would cause the connection to timeout, even if the connection had reconnected.
Player Data Storage
  • New: Improved the error and event logging in Player Data Storage.
  • New: After a write operation, a player data storage file's unencrypted data size is now set in the file's metadata.
  • Bug fix: If LastModifiedTime is not set in the metadata after a write operation, the value of LastModifiedTime is set to EOS_PLAYERDATASTORAGE_TIME_UNDEFINED.
  • Bug fix: Fixed an issue where you could not download or upload game data to the backend service using Player Data Storage due to network instability or unavailability. The EOS SDK retries to download or upload the files to keep Player Data Storage in sync between the SDK and backend service.
  • Bug fix: Fixed an intermittent issue that would cause a crash when you use Player Data Storage's EOS_PlayerDataStorage_WriteFile.
Samples
  • New: Added support for ingesting a non-local player's stats via the ingest command in the achievements sample.
  • New: Added support for setting EOS_AS_Country scope via the -scopescountry command-line argument.
  • New: Added client and server samples for EasyAntiCheat.
  • Bug fix: Fixed an issue where switching focus and clicking on the text field line in samples empties its contents.
  • Bug fix: Fixed a potential issue where a text field widget crashed if the cursor position moved out of range.
  • Bug fix: Fixed a crash in the mods sample due to breaking codepoints during string handling.
Session Based Matchmaking
  • New: You can find out which player owns a session with the EOS_SessionsDetails_Info struct. This value is in one of two forms:
    • The EOS_ProductUserId of the player, if the session is a player hosted listen server.
    • The ClientID of the server, if a dedicated game server created the session.
  • Bug fix: Fixed an issue where calls to EOS_Sessions_UpdateSession failed. This happened when the LocalUserId for the session modifications was unavailable during UPDATE operations.
  • Bug fix: Fixed comments related to the incorrect API_LATEST macros specified in the various options of eos_sessions_types.h.
  • Bug fix: Fixed an issue with EOS_Sessions_RegisterPlayers and EOS_Sessions_UnregisterPlayers not returning the updated player list in callback when called on a non session owner.
Social Overlay
  • New: Integrated Platform on Console expands on the existing Integrated Platform provided for Steam, but now it applies to all the major consoles.
Title Storage
  • New: Improved the error and event logging in Title Storage.
Tools
  • EOS bootstrapper tool
    • The EOS bootstrapper tool is now a stand-alone tool. It no longer requires the EOS bootstrapper application (executable file) in the same directory.
Voice
  • New: Introduced a way to configure rooms behavior when your game enters a background state.
  • New: Added microphone support for Linux.
  • Bug fix: When a Lobby's WebSocket connection is lost, the RTC connection stays up while we attempt to re-establish the WebSocket connection.
  • Bug fix: Fixed a bug where a block request would not work despite the EOS_RTC_BlockParticipant call succeeding if EOS_RTC_BlockParticipant was called for a participant immediately after that participant joined the lobby.
  • Bug fix: Fixed a crash that could occur when a second participant joined a lobby.
  • Bug fix: Fixed an intermittent crash that could happen when the system cannot allocate resources to manage audio devices.
  • Bug fix: Fixed incorrect local AudioStatus when a player enters a room where everyone else is blocked.
  • Bug Fix: Fixed a resource leak when a player leaves the room through internal methods.

Deprecations

Authentication
  • Deprecated: We deprecated Device Code support, EOS_LCT_DeviceCode, for Epic Games accounts sign in.
    • We recommend you stop using EOS_LCT_DeviceCode in the EOS_Auth_Login function or use another authentication method.
Crossplay
  • Deprecated: We deprecated and replaced the struct EOS_Platform_GetDesktopCrossplayStatusInfo with EOS_Platform_DesktopCrossplayStatusInfo for naming consistency.
EOS Core
  • Deprecated: We deprecated and replaced some macros to fit with the standard EOS SDK naming convention of EOS_<system_type>_<function_name>_API_LATEST. We have removed the string OPTIONS from macros in the eos_playerdatastorage_types.h, eos_titlestorage_types.h and eos_private_ui_types.h header files. For example, EOS_PLAYERDATASTORAGE_QUERYFILEOPTIONS_API_LATEST becomes EOS_PLAYERDATASTORAGE_QUERYFILE_API_LATEST.
    • Note: For backward compatibility, the deprecated macros are still present, but we will be removing them in a future version. We recommend replacing any deprecated macros that use the old naming convention with macros that use the new naming convention.
Friends
  • Deprecated: We deprecated unused types related to the previously removed EOS_Friends_DeleteFriend API.
Player Data Storage
  • Deprecated: We deprecated the unused define EOS_PLAYERDATASTORAGE_FILE_MAX_SIZE_BYTES.
Voice

UPGRADE NOTES

Anti-cheat
  • Bug fix: The anti-cheat bootstrapper (start_protected_game) may reject anti-cheat updates because of a file size limit.
    • Note: We recommend updating this executable as soon as possible to avoid errors from future module updates. The executable can be updated without updating the rest of the SDK or recompiling your game.
Authentication

  • New: Updated documentation for Steam Session Tickets authentication to use the new ISteamUser::GetAuthTicketForWebApi Steamworks SDK API, in favor of the now deprecated ISteamUser::GetAuthSessionTicket.

  • Bug fix: Linked Account messages received from the backend are not guaranteed to have an Account ID. This is an expected state, so the AccountId field on EOS_UserInfo_ExternalUserInfo is Optional.

    Note:

    • You should revisit any handling that assumes a specific number of external accounts. For instance, EOS_UserInfo_GetExternalUserInfoCount may return a higher count than previously depending on the external account types in question.
    • The AccountId field of EOS_UserInfo_ExternalUserInfo was nullable before this bug fix. The API has not changed, but the behavior has changed, so if you have code that interacts with the AccountId field of EOS_UserInfo_ExternalUserInfo, it must be verified to check for null values.
Crossplay
  • New: See Crossplay: EOS SDK Best Display Name document for additional information.
  • New: The AllowedPlatformIds and AllowedPlatformIdsCount fields on EOS_Lobby_CreateLobbyOptions and EOS_Sessions_CreateSessionModificationOptions must be initialized; if the lobby is not intended to have restrictions the field should be set to nullptr and 0 respectively. In the case of applications that do not have default initialization, for instance C applications, these fields must be explicitly initialized.
  • New: Platform IDs are located in eos_common.h as well variants of eos_<platform>.h, where <platform> is your specific platform. A lobby created with platform restrictions will only show up in searches that originate from a platform allowed by the lobby or session.
  • New: You now need to determine the bCrossplayOptOut value in EOS_Lobby_CreateLobbyOptions, EOS_Lobby_JoinLobbyOptions, and EOS_Lobby_JoinLobbyByIdOptions.
    • By default, bCrossplayOptOut defaults to EOS_FALSE in order to maintain the existing assumption that lobby creators and joiners permit crossplay by default.
EOS Core
  • New: The EOS SDK supports SteamWorks versions 1.13 and higher. The EOS SDK used to require SteamWorks v1.48 and higher.
  • Bug fix: Fixed an issue in IntegratedSteamSessions, where it was trying to process invites before a login. It now caches the invite.
  • Bug fix: Fixed a WebRTC vulnerability as disclosed by Google for versions M102 and earlier. We are currently on M109. Note: We recommend everyone using prior EOS SDK versions to update to version 1.16 as soon as possible to include this fix. Impacts can be found here.
  • Bug fix: Fixed an issue where building the EOS SDK on Microsoft Xbox GDK printed false warnings about closing sockets during their shutdown.
Lobbies
Session Based Matchmaking
  • Bug fix: Fixed EOS_Sessions_UpdateSession to return EOS_LimitExceeded if a new session cannot be created because doing so would exceed the maximum allowed concurrent session count. Note: We recommend you update the usage of EOS_Sessions_UpdateSession to handle the EOS_LimitExceeded return code.
  • Bug fix: Fixed EOS_Sessions_UpdateSession and EOS_Sessions_JoinSession to return EOS_InvalidUser if the local user associated with the session does not exist or is not authenticated. Note: We recommend you update the usage of EOS_Sessions_UpdateSession and EOS_Sessions_JoinSession to handle EOS_InvalidUser return codes.
  • Bug fix: Fixed EOS_Sessions_RegisterPlayers to return EOS_Sessions_TooManyPlayers when registering the requested number of players would exceed the maximum capacity of the session. This was previously EOS_LimitExceeded. Note: We recommend you update the usage of EOS_Sessions_RegisterPlayers to look for EOS_Sessions_TooManyPlayers instead of EOS_LimitExceeded for cases where the requested number of players would exceed the maximum capacity of the session.

PLATFORM-SPECIFIC

Nintendo Switch
  • New: We updated the Nintendo Switch compilation and link optimizations to compress and reduce binary size. We now use -flto=full and have changed -Os to -Oz (aggressive size).

KNOWN ISSUES AND WORKAROUNDS

Android Login Sample 1.16
  • In EOS SDK version 1.16 the Android login sample has incorrect gradle files. To fix this, please follow these steps:
    1. Delete the following files:
    • Samples\Android\Login\settings.gradle
    • Samples\Android\Login\app\build.gradle
    • Samples\Android\Login\app\src\main\cpp\CMakeLists.txt
    1. Rename the following:

    • build.gradle.out to build.gradle

    • CMakeLists.txt.out to CMakeLists.txt

    • settings.gradle.out to settings.gradle

      Note: Keep these files in the same directories.

    1. Open Samples\Android\Login\app\src\main\cpp\CMakeLists.txt and replace the line set_property(TARGET EOSSDK PROPERTY INTERFACE_INCLUDE_DIRECTORIES ${BASE_PROJECT_DIR}/SDK/Bin/Android/include) to set_property(TARGET EOSSDK PROPERTY INTERFACE_INCLUDE_DIRECTORIES ${BASE_PROJECT_DIR}/SDK/Include)
Anti-cheat Service Installer
  • The Service Installer (EasyAntiCheat_EOS_Setup.exe) provided in EOS SDK version 1.16 has a bug that causes games to fail the launch with the error "StartService failed: 1053". This issue will be fixed in the next release.
Lobbies

  • In EOS SDK version 1.16, if you add an attribute to a lobby using EOS_LobbyModification_AddAttribute without modifying any lobby owner member attributes, the lobby owner member attributes set previously with EOS_LobbyModification_AddMemberAttribute are removed. To address this issue, you must modify, add or remove a member attribute for the lobby owner any time a lobby attribute is modified.

    The attribute value can be anything, as it only matters that one of the member attributes for the lobby owner is changed. You must modify, add or remove the lobby owner attribute as part of the lobby update modification used to change the lobby attribute.

    Example code:

1.15.5 - 2023-feb-16

Anti-cheat

  • New: Improved the anti-cheat metric collection to keep track of the number of players kicked from your game when you have configured anti-cheat with peer-to-peer mode.
  • New: Improved the anti-cheat bootstrapper to log anti-cheat module failures correctly.
  • New: The anti-cheat bootstrapper now supports macOS versions 10.14, and higher. Before this update, it supported macOS versions 11.0, and higher.
  • New: Improved the anti-cheat bootstrapper to display a dialog for you to test unpublished anti-cheat modules. The new dialog shows that a test module was downloaded which eliminates the need for you to look at the log files.
  • New: Players with a local temporary ban can now see the remaining time of their ban in the kick message that is sent to the game server through the EOS SDK. Previously the kick message displayed the local temporary ban without the remaining time of their ban.
  • New: The anti-cheat bootstrapper has been updated to use 64-bit architecture instead of 32-bit architecture.
  • New: Following the anti-cheat bootstrapper architecture change, the anti-cheat service now supports Chromebooks.
  • Bug fix: Fixed an issue where the player tracking functionality would stop sending client data.
  • Deprecated: We deprecated the log file, loader.log, and introduced a new log file, anticheatlauncher.log, as the single log file for the anti-cheat bootstrapper.

Sessions

  • Deprecated: We deprecated the error value, EOS_LimitExceeded for EOS_Sessions_RegisterPlayers. Now EOS_Sessions_RegisterPlayers returns the new error value EOS_Sessions_TooManyPlayers. For games using EOS SDK version 1.15.5 and higher, make sure you set up your games to check for the new error value.

Voice

  • Bug fix: Fixed an intermittent issue where a player's status change in the voice chat room did not call a callback that is set up with EOS_Lobby_AddNotifyRTCRoomConnectionChanged.

UPGRADE NOTES

Anti-cheat

  • New: For games using EOS SDK version 1.15.5 and higher, you must update your anti-cheat modules to the latest version to avoid issues for players.

Sessions

  • New: When you call EOS_Sessions_RegisterPlayers with the parameter EOS_SESSIONS_REGISTERPLAYERS_API_LATEST, the return error value is now EOS_Sessions_TooManyPlayers. If you are not using the parameter EOS_SESSIONS_REGISTERPLAYERS_API_LATEST, EOS_Sessions_RegisterPlayers continues to return EOS_LimitExceeded.

PLATFORM-SPECIFIC

Microsoft Xbox

  • New: Added version support for Microsoft's Xbox GDK version October 2022 QFE1 (221001) as well as Microsoft's Xbox GDK version June 2022 QFE4. (220604).

Nintendo Switch

  • New: Added version support for Nintendo Switch SDK version 15.3.0 and retained support for Nintendo Switch SDK version 14.3.0.

2022

1.15.4 - 2022-nov-16

Anti-cheat

  • New: Improved the AntiCheatServer log output to include information about calls to EOS_AntiCheatServer_SetClientNetworkState.
  • New: Improved the anti-cheat service's server performance by reducing the number of HTTP requests made by the game server to the anti-cheat service. This allows servers to support larger player populations.
  • New: The AntiCheatServer now sends more data to the anti-cheat service when your game calls EOS_AntiCheatServer_LogPlayerDespawn.
  • Bug fix: Fixed a potential issue where, under high server load, the anti-cheat service might kick players from a game session inappropriately.

Authentication

  • Bug fix: EOS_Auth_VerifyIdToken does not return EOS_Auth_InvalidToken for valid ID tokens when you use EOS_Auth_VerifyIdToken before the SDK receives configuration from the EOS Service . EOS_Auth_VerifyIdToken now correctly waits for configuration and returns EOS_Success.

EOS SDK in C#

  • New: The EOS SDK in C# now supports pinning the same buffer multiple times. In addition to improving performance, this allows in-place encryption and decryption of network messages by the anti-cheat service.

Connect

  • Bug fix: EOS_Connect_VerifyIdToken does not return EOS_Connect_InvalidToken for valid ID tokens when you use EOS_Connect_VerifyIdToken before the SDK receives configuration from the EOS Service. EOS_Connect_VerifyIdToken now correctly waits for configuration and returns EOS_Success.

Ecom

  • New: Added a new API, EOS_Ecom_QueryEntitlementToken, in EcomInterface to query the entitlements token.

Social Overlay

  • Bug fix: Players can now see and click on a PROFILE button for all players, regardless of how they are connected to a game session. For example, a player connected to a game session through the Epic Game Store can see and click on the PROFILE button of a player connected through Steam. Previously some players connected through different game platforms could not see each other's PROFILE button.
  • Bug fix: Fixed an issue where EOS_UI_ShowBlockPlayer and EOS_UI_ShowReportPlayer failed. This issue happened when you disabled the Social Overlay with platform flags, which caused the SDK to incorrectly detect the network as disconnected.

Lobbies

  • Bug fix: Players are now limited to 16 concurrent lobbies. Attempting to create more than 16 concurrent lobbies results in an EOS_LimitExceeded error response.

Peer-to-peer

  • New: Peer-to-peer now uses the dcSCTP SCTP library implementation instead of usrsctp. This change addresses security issues with usrsctp, and improves responsiveness during poor network conditions.
    • Note: This change is backward compatible, but we recommend you upgrade to the latest SDK version as soon as possible for improved security and performance.
  • Bug fix: Fixed an issue where an established connection might timeout immediately after any interruptions.

Sessions

  • Bug fix: Players are now limited to 16 concurrent sessions. Attempting to create more than 16 concurrent sessions results in an EOS_LimitExceeded error response.

Stats

  • Bug fix: We have removed the restriction that LocalUserId needs to be the same as TargetUserId for EOS_Stats_IngestStat. This means when you enable the Client Policy setting ingestForAnyUser, a game client can now update player data for all players, for example those connecting through a peer-to-peer in game session: remote players and local players.

UPGRADE NOTES

Lobbies

  • Bug fix: Players are now limited to 16 concurrent lobbies. Attempting to create more than 16 concurrent lobbies results in an EOS_LimitExceeded error response.

Sessions

  • Bug fix: Players are now limited to 16 concurrent sessions. Attempting to create more than 16 concurrent sessions results in an EOS_LimitExceeded error response.

DEPRECATIONS

Anti-cheat

  • Deprecated: We deprecated the string AccountId parameter in EOS_AntiCheatServer_RegisterClientOptions and introduced a new EOS_ProductUserId UserId parameter to replace it. The new EOS_AntiCheatServer_RegisterClientOptions parameter has typing.
    • Note: If your game servers do not yet securely receive the EOS_ProductUserId from game clients, we recommend that you use the EOS Game Services' Connect Interface EOS Connect ID Tokens to get the EOS_ProductUserId.

EOS Core

  • Deprecated: We deprecated and replaced some macros to fit with the standard EOS SDK naming convention of EOS_<system_type>_<function_name>_API_LATEST. We have removed the string OPTIONS from the affected macros: EOS_PLAYERDATASTORAGE_*_API_LATEST and EOS_TITLESTORAGE_*_API_LATEST. For example, EOS_PLAYERDATASTORAGE_QUERYFILEOPTIONS_API_LATEST becomes EOS_PLAYERDATASTORAGE_QUERYFILE_API_LATEST.
    • Note: For backward compatibility, the deprecated macros are still present but we will be removing them in a future version. We recommend replacing any deprecated macros that use the old naming convention with macros that use the new naming convention.

PLATFORM-SPECIFIC

Sony PlayStation

  • New: Added version support for Sony's PS4 Platform SDK version 10.008.001 and retained support for Sony’s PS4 Platform SDK version 9.508.001..
  • New: Added version support for Sony's PS5 Platform SDK version 6.00.00.38 and retained support for Sony’s PS5 Platform SDK version 5.00.00.33.
  • Bug fix: Fixed a bug where games running on PS5 crashed when players with voice chat enabled joined or left lobbies.

Microsoft Xbox

  • New: Added version support for Microsoft GDK June 2022 QFE2 (220602) and retained support for March 2022 QFE1 (220301).

RELEASE NOTES and UPGRADE NOTES

Mobile

Android

  • New: There are now two types of Android SDK. We added a new type of Android SDK, which is static and links with libc++_static.a. The existing Android SDK is dynamic and links with libc++_shared.so.

    SDKs are available for both types in the SDK download. There is one header file for both.

    • The static binary is located in ~/SDK/Bin/Android/static-stdc++.
    • The dynamic binary is located in ~/SDK/Bin/Android/dynamic-stdc++.

    Use the static type if:

    • Your game engine (such as UE5.1), or any libraries in it, use custom new or delete operators. These are not supported well by libc++_shared.so.
    • Your game, or any library in it, uses libc++_static.a. Mixing libc++_static.a and libc++_shared.so is not supported on Android. Make sure that all your code and libraries, and any you use from a third party, are linked with libc++_static.a.

Note

  • If you have already downloaded and are using Epic Online Services SDK version 1.15.2 and your game uses P2P, we strongly recommend that you update to SDK version 1.15.2.1 as soon as possible.
  • We have copied the 1.15.2 release notes here for reference.

1.15.2.1 - 2022-aug-30

RELEASE NOTES

P2P

  • Bug fix: Resolved a new issue in 1.15.2 where a P2P connection between peers timed out shortly after connecting under specific circumstances.

1.15.2 - 2022-aug-26

RELEASE NOTES

New features

Apple silicon support on Mac

  • New: The SDK now supports Apple silicon on Mac as a universal dylib.
    • Note: Anti-cheat currently does not support Apple silicon.

Updates: new, bug fixes, improvements, deprecations

Anti-cheat

  • New: In the configuration file anticheat_integritytool.cfg, you can now configure settings for your game client, such as the maximum number of active instances of your game allowed on a player’s machine.
  • Bug fix: We have resolved a crash in EOS_AntiCheatClient_RegisterPeer that occurred if you used SDK 1.15 without rebuilding your project with new headers.
  • Bug fix: The anti-cheat server no longer retries HTTP requests that failed due to EOS service downtime. In addition, the anti-cheat server no longer retries when the player has left the game session.
  • Bug fix: We fixed a bug in the anti-cheat integrity tool on Unix and macOS that was introduced with SDK 1.15: the tool outputted to the wrong location. The output is now correctly located in the EasyAntiCheat/Certificates folder, which is in line with the behavior of previous SDK versions.
  • Bug fix: Fixed an issue so the anti-cheat bootstrapper no longer tries to load a cached module if the anti-cheat service is disabled.
  • Bug fix: Fixed a crash on SDK initialization for some macOS Monterey systems.
  • Bug fix: Fixed an issue where the anti-cheat bootstrapper lagged on players’ machines running AMD Ryzen CPUs.
  • Bug fix: Fixed an issue where the anti-cheat bootstrapper failed to initialize if the player’s GPU does not support textures larger than 2048x2048.
  • Bug fix: Fixed an issue where the anti-cheat bootstrapper’s user interface was hard to see if the splash screen is primarily white, or has white elements.
  • Bug fix: Fixed a compatibility issue between the Anti-Cheat bootstrapper and the latest version of Arch Linux. This issue will also affect the Steam Deck when attempting to run games compiled for Windows using Proton.
    • To apply the fix, replace the old version of start_protected_game.exe with the new one packaged in this release and proceed to release an up-to-date Linux anti-cheat module for your game on the dev portal. No other changes are needed.
  • Improvement: The anti-cheat bootstrapper’s binary (executable file) is now inside a bundle. This executable bundle means:
    • We have added a default icon to the macOS executable bundle, so it now has the same icon on macOS as it does on Windows.
  • Improvement: The anti-cheat bootstrapper no longer caches its resources onto a player’s machine’s hard disk.
  • Improvement: On Windows, the anti-cheat bootstrapper now displays your game executable’s icon in the taskbar. If you add a custom icon in the ~/<game root>/ EasyAntiCheat directory, it overwrites the default icon.
  • Improvement: The anti-cheat integrity tool now has more usage samples. You can see them by running anticheat_integritytool.exe --help.

Authentication

  • New: If you disable the EOS overlay in your game or it is not installed, Auth Interface uses a system browser so players can sign in.
  • Bug Fix: Fixed an issue where, on a flakey network, the logout callback fired multiple times and returned success multiple times.

Connect

  • Bug fix: Fixed EOS_Connect_Login failing to accommodate UTF-8 character lengths up to the 32 char limit.

EOS core

  • New: iOS and Android samples now use examples of the SDK 1.15 suspend/resume and network connect/disconnect APIs.
  • New: The EOS SDK now requires Steamworks API (EOS_IntegratedPlatform_Steam_Options). You must use the Steamworks API for Steamworks SDK version 1.48 or later. If you use Steamworks earlier than 1.48, Steam integration does not work.
  • Bug fix: EOS_Platform_Create now correctly detects pre-SDK 1.15 header files and treats the default EOS_ENetworkStatus to EOS_NS_Online on all console platforms.
    • Now: On all console platforms, the default network status is offline. This provides better management when you use EOS_Platform_SetNetworkStatus.
    • Previously: On console platforms, you should only call EOS_Platform_Create when the game was online. You needed to call EOS_Platform_Release first if the game was offline. SDK 1.15 did not maintain this if your game used pre SDK 1.15 header files. This fix resolves that.

P2P

  • New: Fixed a performance issue in EOS_P2P_SendPacket that was caused by thread-synchronization blocking in an internal library.
  • New: EOS_P2P_ReceivePacket no longer requires calls to EOS_Platform_Tick to receive new packets.
  • New: Added a new field to EOS_P2P_SendPacket. The new field, called DisableAutoAcceptConnection, allows automatic acceptance of connections in packet-sending logic.
    • If you use this option, your game must always use EOS_P2P_AcceptConnection to open connections.
    • If you use EOS_P2P_SendPacket, it now returns EOS_EResult::EOS_NoConnection when it fails under the following two circumstances:
      • The remote peer has not accepted the connection.
      • The connection has closed since the last time the remote peer accepted it.
  • New: Added a function, called EOS_P2P_AddNotifyPeerConnectionInterrupted, which listens for non-fatal disconnects in the connection. If this function returns a disconnect, one of the following callbacks fire to let your game know the connection status:
    • EOS_P2P_OnPeerConnectionEstablishedCallback - the connection is re-established.
    • EOS_P2P_OnRemoteConnectionClosedCallback - the connection has failed to reconnect and is closed.

Ecom

  • New: Added ReleaseDate and EffectiveDate to EOS_Ecom_CatalogOffer.
  • New* Introduced two new APIs to the Ecom Interface:
    • EOS_Ecom_GetLastRedeemedEntitlementsCount to fetch the number of entitlements that were redeemed during the last EOS_Ecom_RedeemEntitlements call.
    • EOS_Ecom_CopyLastRedeemedEntitlementByIndex to fetch a redeemed entitlement ID from an index.
  • Bug fix: EOS_Ecom_RedeemEntitlements no longer returns Success when passed incorrect entitlement ID(s).
  • Deprecated: We deprecated the PurchasedCount field from EOS_ECom_CatalogOffer.
    • Note: Do not use the PurchasedCount field.
    • Now: The PurchasedCount field always has a value of 0.
    • Previously: In pre-SDK 1.15.2, the EOS service sends PurchasedCount with a value of 0 unless you have configured PurchaseLimit for the offer. We will not support this behavior indefinitely, so do not depend on this value.

Samples

  • New: In the sample projects, Steam login now uses Steam Auth Session Tickets instead of Steam Encryption Application Tickets for improved security.

Session-based matchmaking

  • Bug fix: Fixed EOS_Sessions_JoinSession so it no longer invokes CompletionDelegate multiple times, and no longer returns EOS_NotFound when the operation requires HTTP retries.

Platform-specific

macOS

  • Bug fix: Fixed an issue where the Dev Auth Tool and anti-cheat bootstrapper did not open on macOS.

Console general

  • New: The EOS SDKs for consoles are now pinned to two release versions of a console’s SDK. The two release versions of a console’s SDK (Microsoft’s Xbox SDKs, Sony’s PlayStation SDKs, and Nintendo’s Switch SDKs, for example) are:
    • The latest release version.
    • The previous release version.
    • Note: This applies to the EOS SDK for all consoles and to all future releases of the EOS SDKs for consoles.
  • Bug fix: EOS_Platform_Create now correctly detects pre-SDK 1.15 header files and treats the default EOS_ENetworkStatus to EOS_NS_Online on all platforms. This resolves a backwards compatibility issue on consoles.

Sony PlayStation

  • New: Added version support for PS4 SDK 9.008.001 and retained support for PS5 SDK 4.000.00.31.

Nintendo Switch

  • New: Added version support for Nintendo Switch SDK 14.3.0 and retained support for Nintendo Switch SDK 13.3.2.

Microsoft Xbox

  • New: Added version support for Xbox GDK 220301 and retained support for Xbox GDK 211001.

1.15.1 - 2022-jul-01

1.15 - 2022-jun-16

RELEASE NOTES

New Features

Crossplay

Seamless crossplay on PC: use crossplay to unify your players and your matchmaking pools across Steam and the Epic Games Store. See What's new in the documentation for more details.

Existing Features, New, Bug Fixes, Deprecations

Anti-cheat

  • New: Anti-cheat peer-to-peer mode now supports cross-platform play between PC and console users.
  • New: Replaced the client-side EOS_AntiCheatClient_PollStatus with a callback function which you can access through EOS_AntiCheatClient_AddNotifyClientIntegrityViolated.
  • Bug Fix: Fixed an issue with AntiCheatServer that players could use to cheat by avoiding detection.
  • Bug Fix: Fixed a crash on SDK initialization for some macOS Monterey systems.
  • Improvements: Better error logging for anti-cheat gameplay data features.
  • Improvements: Better error logging for anti-cheat peer-to-peer mode.
  • Deprecation: EOS_AntiCheatClient_RegisterPeerOptions AccountID is now deprecated. PeerProductUserId replaces it.
  • Improvements: The anti-cheat bootstrapper’s binary (executable file) is now inside a bundle. This executable bundle means:
    • We have added a default icon to the macOS executable bundle, so it now has the same icon on macOS as it does on Windows.
    • You can add more modifications to your game running on macOS.
  • Known Issue: Changes to the anti-cheat tooling intended to go live with EOS SDK 1.15 were not included in the SDK and will instead be distributed with EOS SDK 1.15.1.
  • Known Issue:If you call EOS_AntiCheatClient_RegisterPeer using the EOS SDK 1.15 libraries, you must rebuild your game with the new 1.15 headers. If you do not, your game will crash.

Authentication

  • New (Breaking Change): On Windows, the EOS_LCT_AccountPortal and EOS_LCT_ExternalAuth login types now require the EOS redistributable installed with your game.
  • New: The SDK now supports verifiable parental consent. Younger users may be prompted to obtain parental consent for their Epic Account, or for data sharing within a game.
  • New: SDK packages now contain the EOS bootstrapper and EOS bootstrapper tool for use with the EOS redistributable for crossplay on Windows PC.
  • Bug Fix: Fixed an issue where the EOS_Connect_OnLoginStatusChangedCallback did not report that the local user’s authentication session had expired.
  • Bug Fix: Fixed an issue that caused EOS_P2P_QueryNATType to always fail and use the wrong NAT servers if called too soon after EOS_Platform_Create.
  • Bug Fix: Renamed EOS_EResult::EOS_Auth_PersistentAuth_AccountNotActive to EOS_EResult::EOS_Auth_AccountNotActive. This removes Persistent because the Epic Account status it returns is not specific to only the persistent (EOS_LCT_PersistentAuth) login type.

EOS Core

  • New: Added EOS_Platform_GetDesktopCrossplayStatus API for Windows PC. Games distributed outside the Epic Games Store can use this API to verify that the in-game overlay for Epic Account login is readily available.

  • New (Breaking Change): Added the APIs listed below to the Platform Interface. They inform the SDK when the game gets suspended and resumed, and when the network connectivity state of the local system changes.

    There are four new APIs:

    • EOS_Platform_SetApplicationStatus
    • EOS_Platform_SetNetworkStatus
    • EOS_Platform_GetApplicationStatus
    • EOS_Platform_GetNetworkStatus
    • All games must now call the two Set APIs for the SDK to work correctly:
      • EOS_Platform_SetApplicationStatus
      • EOS_Platform_SetNetworkStatus

Known Issue: iOS and Android samples are currently not updated with examples of the new suspend / resume and network connect / disconnect APIs.

  • New: Added types EOS_EApplicationStatus and EOS_ENetworkStatus.
  • New: When a game client resumes to a foreground state, the SDK now updates the auth token’s expiration, based on the time that elapsed when it was in a background state.
  • New: Redacted display names from the SDK logs because this is personal player information.
  • New: Redacted continuation tokens from the SDK logs because this is sensitive information.
  • New: Updated the EOS_Ecom_QueryOwnership limit from 32 to 50 to bring the SDK in line with the EOS service request limit of 50.
  • Improvements: Updated the SDK build version string returned by EOS_GetVersion to contain the platform it relates to.

Friends

  • New: Enabled EOS_Friends_SendInvite, EOS_Friends_AcceptInvite, and EOS_Friends_RejectInvite. Games can call these APIs to let players make new friend connections in-game. These APIs were not enabled in previous SDK versions.

Lobbies

  • New: Added new notification functions EOS_Lobby_AddNotifyLobbyInviteRejected and EOS_Lobby_RemoveNotifyLobbyInviteRejected.
  • New: Added EOS_CustomInvites_AddNotifyRejected and EOS_CustomInvites_RemoveNotifyRejected functions to bring custom invites in line with the Lobbies Interface and Sessions Interface.
  • Bug Fix: Added additional error messages related to players who are interacting with the voice features of the SDK. The error messages now report when players are not found.
  • Bug Fix: Invites to a lobby are now identifiable by the player who sent the invite. If a player has invites to a lobby from various friends, when the player accepts one of the invites, the Social Overlay now removes all the player’s unused invites.

P2P

  • Bug Fix: Fixed an issue that caused EOS_P2P_QueryNATType to always fail and use the wrong NAT servers if called too soon after EOS_Platform_Create.
  • Bug Fix: Greatly reduced the CPU performance cost of EOS_P2P_SendPacket.

Player Data Storage

  • Bug Fix: Improved the performance of file reads during the hashing of cached files in player data and title storage file reading and writing flows.

Samples

  • Bug Fix: Fixed EOS_UserInfo_CopyUserInfoOptions to use the correct API version type EOS_USERINFO_COPYUSERINFO_API_LATEST.
  • Improvements: Changed the Visual Studio Debug and Release project configuration build defaults to Debug_SDL and Release_SDL.
  • AuthAndFriends Sample:
    • Improved the UI on the custom invites dialog box.
  • Voice Sample:
    • Added support for setting an individual player’s audio volume.

Social Overlay

  • New: Added EOS_UI_PauseSocialOverlaywhich pauses the Social Overlay and EOS_UI_IsSocialOverlayPaused which checks if the Social Overlay is paused.
    • While paused, the Social Overlay is not displayed.
    • Pause the Social Overlay during cut-scenes to prevent toasts and temporarily keep the player immersed in your experience.
  • New: Added EOS_UI_ShowBlockPlayer and EOS_UI_ShowReportPlayer. These send a state update to the Social Overlay requesting that a player is blocked or reported.
  • New: Added EOS_UI_GetFriendsExclusiveInput so your game can immediately check whether the Social Overlay is in exclusive input mode. Previously games had to keep track of this state using the EOS_UI_OnDisplaySettingsUpdatedCallback callback.
  • New: The Social Overlay now shows a player ALL their Epic friends. This includes Epic friends who have never played the game a player is playing.
  • New: Added functionality so players can:
    • Search Epic friends
    • Manage Epic friends: add and remove friends, accept and deny incoming friend invites, and cancel outgoing friend invites
    • Block Epic friends
    • Report Epic friends
  • New: The Social Overlay can now show cross-platform friends alongside Epic friends: Players who launch your game from the Epic Games Store can see friends who launch your game from Steam.
  • Bug Fix: The Invite button no longer displays when a lobby is full.
  • Improvements: The Social Overlay is hidden when a game’s status changes or the network is disconnected.

User Info

  • New: Added DisplayNameSanitized to EOS_UserInfo and EOS_UserInfo_ExternalUserInfo. This contains the sanitized display name when your game is running on platforms that have sanitization support.

Voice

  • New: Added bParticipantInBlocklist field to EOS_RTC_ParticipantStatusChangedCallbackInfo which reports when a player is added or removed from a block list. Use this to know when a player can’t be heard in a lobby because they are on a block list.
    • Note: This is an automatic enforced internal block which you can’t override.
  • New: Added EOS_RTCAudio_UpdateParticipantVolume for audio volume control that extends (and replaces) the existing volume control.
  • Bug Fix: Allowed setting NoAffinityMask on RTC threads.
  • Bug Fix: Fixed an issue on macOS where the audio input device did not recognize any devices.
  • Deprecation: Deprecated LocalUserId and LobbyId in the EOS_Lobby_AddNotifyRTCRoomConnectionChangedOptions struct.

C# SDK

  • New (Breaking Change):

    • Changed most reference types (classes) to value types (structs), giving significant performance gains.
    • You must use the ref keyword when you pass options structs in API calls.
    • You must use the ref keyword when you pass info structs in callbacks.
    • Because reference types (classes) are now value types (structs), there might be new bugs in your code, depending on how you assign options and pass them in API calls. We recommend testing for regressions in this area.

  • New: The SDK now uses byte[] instead of ArraySegments to prevent unnecessary copies of data.

  • New: Added a new Utf8String class to reduce the UTF-16 to UTF-8 conversions.

  • New: Added fixes, optimizations, and improvements to the wrapper code.

  • Bug Fix: Added dynamic binding symbol mappings for Win32 and macOS.

Tools

Developer Auth Tool

  • New: The tool persists the port chosen by the player. On successive launches, this port is automatically selected in the UI.
  • New: The tool remembers player credentials between uses, without requiring player logins to refresh it.
  • Bug Fix: The tool refreshes player credentials when it runs for long durations.

LIBRARIES

  • New: Updated openssl-1.1.1n.

UPGRADE NOTES

Anti-cheat

  • See the documentation for details on how to use peer-to-peer mode in cross-platform play.
    • Note: To ensure authentication works correctly with this feature, you must update the SDK for PC and console platforms simultaneously when you use this feature.

PROGRAMMING UPGRADE NOTES

Authentication Breaking Change

  • On Windows, the EOS_LCT_AccountPortal and EOS_LCT_ExternalAuth login types now require the EOS redistributable installed, and your game must launch with the EOS bootstrapper.

EOS Core Breaking Change

  • All games must now call the following two APIs for the SDK to work correctly:
    • EOS_Platform_SetApplicationStatus
    • EOS_Platform_SetNetworkStatus
  • Added these APIs to the Platform Interface. They inform the SDK when the game gets suspended and resumed, and when the network connectivity state of the local system changes. You can use two new related APIs optionally, to check the status:
    • EOS_Platform_GetApplicationStatus
    • EOS_Platform_GetNetworkStatus

Known Issue: iOS and Android samples are currently not updated with examples of the new suspend / resume and network connect / disconnect APIs.

C# SDK Breaking Change

  • Changed most reference types (classes) to value types (structs), giving significant performance gains.
  • You must now use the ref keyword when you pass options structs in API calls.
  • You must now use the ref keyword when you use info structs in callbacks.

Voice

  • When a player joins an RTC room, they are initially blocked until their real block status is resolved. This means that there is more than one notification of their block status: ParticipantStatus is set to EOS_RTCPS_Joined and their bParticipantInBlocklist is initially set to true before updating to their real block status.
  • The LocalUserId and LobbyId fields of EOS_Lobby_AddNotifyRTCRoomConnectionChangedOptions are now deprecated.
    • The registered callback is now called for all local users and lobbies.
    • If the game needs to perform any filtering, use the LocalUserId and LobbyId in the EOS_Lobby_RTCRoomConnectionChangedCallbackInfo callback parameter.

Platform-specific

Console General

  • Bug Fix: Fixed an issue where EOS_RTC_XXX functions could have attempted to use the network before it was valid to. EOS_RTC_XXX functionality now respects the current EOS_HPlatform network status value.

Steam

  • New: When running on a platform that supports native sanitization, the DisplayName field in EOS_UserInfo and EOS_UserInfo_ExternalUserInfo now has a DisplayNameSanitized counterpart representing the version of that name that the platform’s sanitization or filtering functionality has processed.
  • Bug Fix: Updated the Steam friends interface to use additional friend flags for blocked users.

Sony PlayStation

  • Updated to PS4 SDK 9.508.001 and PS5 SDK 5.00.00.33.

Nintendo Switch

  • Updated to Nintendo Switch SDK 13.3.2.
  • Deprecation: The OnNetworkRequested callback in EOS_Switch_InitializeOptions is now deprecated and replaced by the new EOS_Platform_OnNetworkStatusChanged API.
  • Lobbies
    • New: The EOS SDK now respects and automatically enforces the Nintendo Switch Online membership permission requirement, when it’s applicable for online matchmaking.

Microsoft Xbox

  • Updated to Xbox GDK to version 211001.
  • Added support for the EOS developer auth tool on Xbox GDK platforms.
    • Treat the target IP address of the developer auth tool as a local IP, such as 192.168.x.x, 10.x.x.x, 127.x.x.x, 172.16.x.x through 172.31.x.x, or the equivalent IPv6 addresses.
    • Hostnames are not supported at this time.
    • Only use this feature for development and testing: use the GDK's own authentication to log in users in real-world scenarios. This feature does not work on retail devices.
  • Bug Fix: Fixed a bug in GDK Sanitizer that could result in unlimited re-sanitization calls to Microsoft services.

1.14.2-hf-2 - 2022-jul-07

Note - If you ship your game on Steam:

  • If you have already downloaded and are using the Epic Online Services SDK for C or C# versions 1.14.2 or 1.14.2-hf-1, you need to download the 1.14.2-hf-2 hotfix version of the SDK for C or C# and use it instead.

2021

1.14.1 - 2021-nov-08

RELEASE NOTES

New Features:

  • Custom Invites

    The Custom Invites feature is designed for developers who want to use their own grouping technology while still taking advantage of the Social Overlay and Epic Games Launcher invite buttons and prompts.

    Developers provide an arbitrary string payload for transmission to other players, and this payload is sent either through direct API call or via the Social Overlay Invite button. Players on the receiving side will see the same Social Overlay Invite Received prompts as with EOS Sessions and Lobbies, and received invites can also trigger new EOSSDK API callbacks if desired.

  • Added CustomInvites UI elements and functionality to AuthAndFriends sample.

  • A Send Invite button opens a send invite dialog which allows the user to set a payload and choose a target user, and ultimately "send" an invite. Instead of using the Send button, the Overlay can also be opened where a Send button will appear next to any users currently eligible to receive the invitation.

  • When an invite is received, a dialog appears with detail about the invite and offers Accept and Decline buttons which ultimately call FinalizeInvite with Success/Canceled results.

AntiCheat

  • New: Added verbose logging support for the bootstrapper, this is enabled by passing either of the following as command line arguments: -v or --verbose.
  • New: The bootstrapper now supports custom runtime icons on Windows, to use a custom icon place a BootstrapperIcon.ico under the <working_dir>/_EasyAntiCheat/_ directory.
  • Bug Fix: Fixed AntiCheatServer backend timeout errors when running with a very high number of players in a single game server.
  • Bug Fix: Fixed a potential crash with a very high number of players in a single game server or with a poor backend connection.
  • Bug Fix: Fixed AntiCheatClient PollStatus function having an out parameter incorrectly named ViolationType instead of OutViolationType.
  • Bug Fix: Fixed AntiCheatClient PollStatus function lacking correct out parameter marshaling in the C# SDK.
  • Bug Fix: The bootstrapper is now code signed on Windows.
  • Bug Fix: The bootstrapper now displays an error if the executable field defined through Settings.json targets a directory.
  • Security improvements.

Authentication

  • Bug Fix: Fixed EOS_Auth_CopyIdToken not providing an ID Token for logins using the EOS_ELoginCredentialType::EOS_LCT_AccountPortal and EOS_ELoginCredentialType::EOS_LCT_DeviceCode credential types.

Connect

  • Added user authentication support using Epic Account ID Tokens with a new EOS_EExternalCredentialType::EOS_ECT_EPIC_ID_TOKEN credentials type.
  • Added Amazon as a supported user authentication provider.
  • Extended EOS_Connect_VerifyIdToken to return information about the external account associated with the verified Product User ID.
  • Updated header commenting for EOS_Connect_QueryProductUserIdMappingsOptions struct to callout usage with dedicated servers.

Core

  • Bug Fix: Fixed an issue where builds launched via EGS Launcher would crash on Mac
  • Minimum supported macOS version has been changed from 10.14 to 10.12.

Lobbies

  • Bug Fix: Fixed a bug where create/join lobby would fail and destroy any existing lobbies by closing the active connection.

Social Overlay

  • New: Added the CustomInvites Interface to provide developers the ability to transmit/receive arbitrary payloads with the same high-level functionality provided by EOS Lobbies and Sessions.
  • New: Added CustomInvites UI elements and functionality to AuthAndFriends sample.
    • A Send Invite button opens a send invite dialog which allows the user to set a payload and choose a target user, and ultimately "send" an invite.
    • When an invite is received, a dialog appears with detail about the invite and offers Accept and Decline buttons which ultimately call FinalizeInvite with Success/Canceled results.
    • Custom Invites Interface: Added Payload as a parameter in the OnCustomInviteReceived and OnCustomInviteAccepted callback infos
  • Custom Invites - Added EOS_CustomInvites_NotifyCustomInviteAccepted, EOS_CustomInvites_RemoveNotifyCustomInviteAccepted and EOS_CustomInvites_NotifyCustomInviteProcessed

CONSOLE SPECIFIC

1.14 - 2021-sep-23

RELEASE NOTES

New Features:

  • Progression Snapshot, (Account Merge Service Preview)
    • Added a new feature in preparation for the introduction of account merge.
    • Progression snapshots are a way for developers to store key/value pairs about user progress in the application. This information will be used by account merge to help users make choices when combining account progress. See documentation for details.

AntiCheat

  • New: Added anti-cheat client support for Linux, including Wine/Proton
  • New: Added anti-cheat client support for Mac (Intel-based)
  • Bug Fix: Fixed bug causing anti-cheat gameplay data UnregisterClient event to not be sent.
  • Bug Fix: EOS_AntiCheatServer_RegisterEvent no longer accepts '.' as part of an event name. This previously caused rejection by the backend but without a clear error.
  • Bug Fix: Fixed internal bug causing anti-cheat gameplay data UnregisterClient event to not be sent.
  • Bug Fix: Fixed possible anti-cheat issues if the system clock is updated at just the wrong moment.
  • Bug Fix: Fixed anti-cheat client module testing workflow not working correctly and leading to a "connection failed" error.
  • Updated Anti-Cheat ProtectMessage and UnprotectMessage APIs so that the final parameter OutBytesWritten only needs to be a valid pointer to an integer. Previously the integer needed to be initially set to the length of the output buffer.
  • Renamed anti-cheat ProtectMessage and UnprotectMessage API positional parameters for better clarity and consistency.
  • Added DamagePosition to EOS_AntiCheatCommon_LogPlayerTakeDamageOptions and deprecated HitBoneId This provides more accurate information about hit locations.
  • Anti-Cheat client modules are now managed at the Deployment level rather than the Sandbox level. This is more consistent with other EOS services. You must be sure to update the EOS_AntiCheatTools files when updating your game to this version of the SDK.
  • The EOS Connect DeviceID auth method is not supported for anti-cheat. A new result code EOS_AntiCheat_DeviceIdAuthIsNotSupported is now returned for this case.

Authentication

  • New: Added new APIs EOS_Auth_CopyIdToken, EOS_Auth_QueryIdToken, and EOS_Auth_VerifyIdToken to allow game servers, online backends and other clients to securely verify identities of other Epic account users. Games using the existing EOS_Auth_CopyAuthToken and EOS_Auth_VerifyAuthToken APIs should consider switching to use ID tokens instead.
  • New: Added API support to detect a merged Epic account state for local users. This is relevant for an upcoming Epic Account Services functionality that will allow users to merge their separate Epic accounts into a single Epic account.

Connect

  • New: Added new APIs EOS_Connect_CopyIdToken and EOS_Connect_VerifyIdToken to allow game servers, online backends and other clients to securely verify another EOS user's identity.
  • New: Added EOS_Connect_CopyIdToken, EOS_Connect_IdToken_Release, and EOS_Connect_VerifyIdToken APIs for the management of Connect ID Tokens. For more information, see the Connect Interface documentation.

ECommerce

  • New: Exposed DecimalPoint for the provided price in EOS_Ecom_CatalogOffer structure. For example, DecimalPoint '2' and CurrentPrice64 '12345' would be '123.45'.

Overlay Tech Platform

  • Bug Fix: Notification callbacks added by EOS_UI_AddNotifyDisplaySettingsUpdated and then removed by EOS_UI_RemoveNotifyDisplaySettingsUpdated before ticking are never invoked. Previously they would have been invoked once and if the game had freed some dependent state, a crash was possible.

P2P

  • It is now possible to get notifications when a connection is established with EOS_P2P_AddNotifyPeerConnectionEstablished and EOS_P2P_RemoveNotifyPeerConnectionEstablished.
  • It is now possible to clear queued incoming and outgoing packets for/from a given remote user and specific socket with EOS_P2P_ClearPacketQueue.

Player Data Storage

  • Bug Fix: Fixed an issue where reading files from the local cache of Player Data Storage could be very slow.
  • Improved PlayerDataStorage logging for many error cases.

Presence

  • Bug Fix: Fixed an issue when Presence service would keep trying to auto-update status when connection is lost.

Samples

  • Bug Fix: Fixed building Leaderboard sample on Mac / Linux by adding missing AssetUtils.cpp to Makefile.

Sanctions

  • Added TimeExpires and ReferenceId fields to EOS_Sanctions_PlayerSanction. This information was already visible in the EOS Developer Portal but previously not available through the SDK API.

Voice

  • Exposed EOS_RTC_SetSetting and EOS_RTC_SetRoomSetting APIs
    • DisableEchoCancelation Disables the use of echo cancellation for the audio channel. Default False
    • DisableNoiseSupression Disables the use of noise suppression for the audio channel. Default False
    • DisableAutoGainControl Disables the use of auto gain control for the audio channel. Default False
    • DisableDtx Global\Per room Allows to disable the use of DTX. Default False

Mobile

iOS

  • Bug Fix: Fixed an issue where an exception could occur on iOS 14 due to invalid characters in the URL scheme.

UPGRADE NOTES

AntiCheat

  • When upgrading to SDK 1.14, you must update the files start_protected_game.exe, EasyAntiCheat_EOS_Setup.exe, and anticheat_integritytool.exe to the latest versions from the bundled EOS_AntiCheatTools zip file.
  • Changes in the start_protected_game.exe:
    • The following settings are no longer supported, these were previously defined in the associated Settings.json:
      • parameters: The bootstrapper now forwards all parameters to the game process that were provided to it upon process start, therefore the associated Settings file doesn't offer this functionality.
      • use_cmdline_parameters: Removed as redundant due to the parameters field being removed.
      • working_directory: Removed as we're now expecting that the bootstrapper is stored in the game's root directory, this applies to all supported platforms.
      • logo_position: Removed due to the bootstrapper's new design that limits the positioning.
      • hide_splash_screen: Removed due to changes in the bootstrapper's internal design.
      • hide_ui_controls: Removed due to changes in the bootstrapper's internal design.
  • If you want to activate Wine/Proton support for your Windows game, you must activate a Linux module in the EOS Developer Portal. See the EOS developer documentation for further details.

PROGRAMMING UPGRADE NOTES

AntiCheat

  • Usages of EOS_AntiCheatCommon_LogPlayerTakeDamageOptions should be updated to set the DamagePosition field instead of HitBoneId. This provides more accurate information about hit locations.

1.13.1 - 2021-july-27

RELEASE NOTES

C# SDK

  • Bug Fix: Fixed compatibility issues with C# versions <7.
  • Bug Fix: Fixed iOS Config targets.

Lobbies

  • Renamed the EOS_Lobby_LocalRTCOptions parameter bAudioOutputStartsMuted to bLocalAudioDeviceInputStartsMuted to better describe what is muted.
  • Bug Fix: Removed an erroneous warning during lobby update. The client can possibly be aware of more attributes than the backend while updates are in flight. This was generating false "out of sync" errors.
  • Bug Fix: Fixed a crash when the RTC initialization options were not specified on EOS Platform Creation, but Lobbies had the RTC Room feature enabled. In this case, lobby creation will now fail with an EOS_InvalidRequest result.
  • Bug Fix: Fixed an incorrect warning that would always occur when using the Lobbies RTC Room feature.

Player Data Storage

  • Added additional logging in some error cases for EOS_PlayerDataStorage_QueryFile, EOS_PlayerDataStorage_QueryFileList, and EOS_PlayerDataStorage_ReadFile.

PROGRAMMING UPGRADE NOTES

Lobbies

  • Usages of the EOS_Lobby_LocalRTCOptions parameter bAudioOutputStartsMuted must be renamed bLocalAudioDeviceInputStartsMuted.

Console Specific

PlayStation

  • New: Set PS5 SDK version to 3.00.00.27
  • New: Set the PS4 SDK version to 8.508.001

Nintendo Switch

  • Bug Fix: Fixed an issue where P2P could get stuck thinking the network was not available if the network was not available the first time P2P was used. P2P now always correctly resumes when the network becomes available again.
  • Bug Fix: Fixed an issue where asynchronous Lobby API calls could take a very long time to timeout when the network is unavailable.

Xbox Series X|S

  • Bug Fix: Fixed an RTC audio capture issue on Xbox Series X|S.

1.13 - 2021-jun-21

RELEASE NOTES

New Features:

  • Voice (Preview Service): The initial release of our EOS Voice tool as part of Epic Online Services allows your players to talk to their friends or teammates in your game without using a third party solution. See documentation for details.

Lobbies

  • New: Added automatic Real Time Communication (RTC) Room support to Lobbies.
    • This feature handles automatically creating, joining, and maintaining connections to a dedicated RTC Room for the lobby when enabled. This feature requires enabling the createLobbyConference Voice permission in the EOS developer portal.
  • New: Lobby creation now allows for the specification of a "lobby id override".
    • The values need to be universally unique within the context of the application.
  • Bug Fix: Fixed log message for EOS_Lobby_RejectInvite when InviteId is null or empty.
