1.0.2

April 28, 2026

Fixed

Fix very rare bug that objects could be created during Garbage Collector phase, what would end up in failing construction of the UObject.

1.0.1

April 20, 2026

Fixed

Fix compilation errors when C++ 20 support is not enabled by replace designated initializers. Fix not initialized properly errors printed for some UStruct properties.

1.0.0

April 2, 2026

Added

The subsystem now supports multiple simultaneous chat sessions keyed by UserID. All public methods now have synchronous and asynchronous variants. Async methods use the 'Async' suffix and accept a delegate for handling the result. Entity objects (channels, users, memberships, messages) are now synchronized by ID. All references to the same entity ID share the latest locally known data, so updating one instance updates the others. Added a chat config option to specify which channel types publish read receipt events. Memberships can now be hard-deleted. Added methods for retrieving and checking singular memberships for users and channels. Added a plug-and-play chat UI sample in Content/SampleChat, including the W_PubnubChat_Sample widget. Added a utility AppendText() method to Membership. Added GetMessageElements() to Message. It returns the same data model as MessageDraft.
