2.3.8
Release 2.3.8 is ready to use with Unreal Engine 5.7.
UE5.7 Upgrade Fixes:
- Removed the unused
SEARCH_PRESENCEkey from the lobby search key mapping and related query filter logic, simplifying lobby search parameter handling. - Removed dead code related to session search on Win64, as the new join logic no longer relies on this path.
Bug fixes:
- Added a new
CleanupFailedJoinSessionmethod toFOnlineSessionPlayFabto ensure proper cleanup of PlayFab and Party sessions, removal of local session references, and delegate notification when a native session join fails. This method is now called in all relevant failure paths.
