## 1.1.0 *September 11, 2025* | Type | Changes | |------|----------| | **Added** | • Add implementation of Entities: `Channel`, `ChannelGroup`, `ChannelMetadata`, `UserMetadata` with all related PubNub functions. • Add implementation of `Subscription` and `SubscriptionSet` objects. Add all necessary operations to add, remove, get subscriptions. • Add implementation of Event Listeners - user can now bind a delegate to subscription for every event type separately or all of them at once. | | **Fixed** | • Clean up properly all C-Core subscriptions after `UnsubscribeFromAll`. | ## v1.0.0 *August 19, 2025* | Type | Changes | |------|----------| | **Added** | • Add code samples for all UE SDK functions - they can be found in `PubnubLibraryTests` module in `Samples` directory. • Add encryption support for AES and Legacy Cryptors - compatible with other PubNub SDKs encryption. • Introduce a unified result field `FPubnubOperationResult` in delegates across all SDK functions. • Add a delegate that can be used to listen for Subscribe and Unsubscribe functions completion result. | | **Fixed** | • Fix bug that in some functions using UTF8 characters would break the function. • Fix bug that using AppContext functions with `Limit` over 100 would crash the engine. Now `Limit` will be clamped to accepted values. • Fix bug that in some cases `SetAuthToken` would not work correctly. Add correct lifetime management for the provided token. | | **Modified** | • Rework `ParseToken` to return permissions in a more user-friendly format. • Remove `CipherKey` from `FPubnubPublishSettings`. • Rework `SetMemberships` and `SetChannelMembers` to have inputs as `FPubnubMembershipInputData` and `FPubnubChannelMemberInputData` instead of raw strings. • Remove deprecated '_JSON' functions. • Add functionality to skip some false warnings logged from C-Core. • Refactor the code to be much cleaner and commented properly. • Add `supported-unreal-engine-versions` field to .pubnub.yml file, so it can be used in documentation. Revisit and fix all other entries in .pubnub.yml. | ## v0.3.3 *June 16, 2025* | Type | Changes | |------|----------| | **Fixed** | • Fix compilation errors that were present in UE 5.1 and UE 5.2 versions. | ## v0.3.2 *June 10, 2025* | Type | Changes | |------|----------| | **Added** | • Add function DeleteMessages which can be used to delete messages from the history. • Add function InitPubnubWithConfig which can be used to initialize PubnubSubsystem with custom config, separate from Project Settings. | | **Modified** | • Add PubSub samples • Fix compilation warnings | ## v0.3.1 *May 27, 2025* | Type | Changes | |------|----------| | **Added** | • Add new overloads, for all function that return data, with native (not dynamic) delegates that can be used with Lambdas. • Add publish/signal message serialization and deserialization - now any string can be send by those methods. • Add unit and integration tests for all end points. | | **Fixed** | • Fix bug that UserID was not set immediately. • Fix bug that only published messages were received from subscription, but not signals and other types. • Fix bugs that group operations were sometimes returning previous responses. • Fix bug that MessageCounts function was not always returning correct count. • Fix incorrect sort and include parameters related to users. | ## v0.3.0 *April 29, 2025* | Type | Changes | |------|----------| | **Added** | • Rework GetMemberships, GetChannelMembers, GetAllUsersMetadataand GetAllChannelsMetadata to have dedicated structures for Include and Sort fields.
