## [1.11.0] - 2024-08-20

### Added

- Added `NetworkVariable.CheckDirtyState` that is to be used in tandem with collections in order to detect whether the collection or an item within the collection has changed. (#3005)

### Fixed

- Fixed issue by adding null checks in `NetworkVariableBase.CanClientRead` and `NetworkVariableBase.CanClientWrite` methods to ensure safe access to `NetworkBehaviour`. (#3011)
- Fixed issue using collections within `NetworkVariable` where the collection would not detect changes to items or nested items. (#3005)
- Fixed issue where `List`, `Dictionary`, and `HashSet` collections would not uniquely duplicate nested collections. (#3005)
- Fixed Issue where a state with dual triggers, inbound and outbound, could cause a false layer to layer state transition message to be sent to non-authority `NetworkAnimator` instances and cause a warning message to be logged. (#2999)
- Fixed issue where `FixedStringSerializer<T>` was using `NetworkVariableSerialization<byte>.AreEqual` to determine if two bytes were equal causes an exception to be thrown due to no byte serializer having been defined. (#2992)

### Changed

- Changed permissions exception thrown in `NetworkList` to exiting early with a logged error that is now a unified permissions message within `NetworkVariableBase`. (#3005)
- Changed permissions exception thrown in `NetworkVariable.Value` to exiting early with a logged error that is now a unified permissions message within `NetworkVariableBase`. (#3005)
