Release Notes

Current - After v5.0.2

Removed the tracked Source/ThirdParty/EIKSDK_1.18_backup SDK copy from the repository.
Added ignore coverage so the backup SDK stays out of source control.
Included the unzipped Windows DevAuthTool executable at Source/ThirdParty/EIKSDK/Tools/EOS_DevAuthTool-win32-x64-1.2.1/EOS_DevAuthTool.exe.
Added Git LFS coverage for ThirdParty .exe files so packaged tooling is stored consistently with the other SDK binaries.

This update collects the important changes since v5.0.1.

Updated the bundled Epic Online Services SDK from 1.18.1.2 to 1.19.0.3 across desktop and Android.
Added SDK 1.19 compatibility fixes, including the EOS_INITIALIZE_API_LATEST static assert update and the replacement for the deprecated ecom transaction ID length constant.
Added full Anti-Cheat Blueprint SDK coverage with client/server subsystems and shared Anti-Cheat types.
Added voice chat support through the EIK Core V1/V2 interfaces and a new Blueprint voice chat library.
Added Blueprint external UI nodes for achievements, report player, and store UI.
Expanded OSSv2 support and unblocked Online Services usage on UE 5.5 and UE 5.6 when the required modules are available.

Improved OSSv1 auto-login behavior, including PIE and DevAuthTool workflows.
Fixed login startup and shutdown edge cases that could leave stale mappings or crash during auth state changes.
Added a login patch for EOS ID conversion and user manager state handling.
Improved Epic Account login callback handling so failures produce consistent Blueprint results.

Fixed Join Lobby behavior in both EIK Core and Online Subsystem paths.
Added support for Device ID sign-ins joining presence lobbies.
Improved session result handling, socket address conversion, user registration, and cached session/user lookups.
Fixed OSSv2 lobby query behavior and lobby result conversion.
Improved presence and session handling in OnlineServicesEIK.

Fixed an OSSv1 user query crash.
Improved Product User ID and Epic Account ID resolution across UserInfo, OnlineServicesEIK, and the OnlineSubsystem user manager.
Added safer handling for empty or invalid account IDs.

Added OnlineErrorEIK wrappers and shared OnlineServices ID helpers.
Improved OnlineServicesEIK error conversion and account ID conversion.
Updated achievements, auth, commerce, external UI, leaderboards, presence, social, stats, title file, user file, and user info paths to use the current EIK naming and error handling.
Added version macros for UE 5.5, 5.6, and 5.7 feature checks.

Sanitized EOS/EIK naming conflicts in shared SDK code.
Renamed internal EIKShared SDK wrapper files and types back to the EIK namespace style to avoid collisions with Epic EOS symbols.
Updated voice, socket, online subsystem, and SDK function code to use the cleaned-up names.

This is still an alpha release.
Projects using internal EIKShared C++ headers may need include/name updates because several internal EOS* wrapper names were changed to EIK*.
OSSv2 support now starts earlier than the original v5.0.1 note: UE 5.5+ can use it when the required OnlineServices modules are present.

This is an alpha release. If you have a game release coming up soon, stay on v4 - it's stable and battle-tested.

v5 Alpha is available exclusively on our website for now. Marketplace release will follow later.

Play in Editor (PIE) Support - Test your EOS integration without leaving the editor. No more standalones.
