- Graphics: Fixes incorrect gamma decoding at import of LDR textures that target a HDR graphics format in a gamma colorspace project
- Graphics: Fixes two issues related to counterbuffers in Vulkan - If one only uses the counter the buffer is now correctly bound; Updating the data on the buffer does not invalidate the counter
- Graphics: Metal: Disable Graphics Jobs support for Nvidia GPUs
- IL2CPP: Correct the behavior of the InitMessage icall

- Particles: - Fixed Mesh that contains blend shapes sometimes not being marked as read/write enabled when it is used by a ParticleSystems ShapeModule
- Fixed crash when assigning a Mesh with blend shapes to a ParticleSystems ShapeModule through a script in a Player build. A warning will now be thrown to report that the Mesh must be read/write enabled
- Particles: Fixed Sub Emitter fields having too much vertical separation and the Object Field selector button being too large
- Physics: Rigidbody2D MovePosition/MoveRotation now result in the correct target position/rotation when using manual simulation with time-step that isn't Time.fixedDeltaTime
- Playables: Fixed out of order evaluation of Control Tracks in Timeline when using multiple nested timelines
- Profiler: Profiler: Fixed -profiler-maxusedmemory cmdline parameter for standalone players
- Profiler: Increased maximum memory that can be used by profiler to 128MB
- Scripting: Fixed editor freeze/crash when interacting with Native Audio Plugin SDK's Audio Mixers
- Shaders: Fixed Editor crash when calling ShaderUtil.ClearCachedData() while still async compiling shader variants
- Timeline: Fix issues related to recursive control tracks
- Timeline: Fixed adjacent recording clips highlighting the wrong clip
- Timeline: Fixed avatar mask reassignment not causing immediate re-evaluation
- Timeline: Fixed issue where changes to a Signal Receiver component in a prefab were reverted
- Timeline: Fixed issue where using the HideInMenu attribute in combination with a class inheriting from Marker would not hide the marker from the Timeline context menus
- Timeline: Fixed Performance issue where Control Tracks would resimulate during the tail of a non-looping particle clip
- Timeline: Fixed SignalReceiver.ChangeSignalAtIndex incorrectly throwing exception when multiple entries are set to null
- Timeline: Fixed timescale drawing to only draw visible lines which avoids a hang with very large clips
- UI: IME properly works and is in the correct location
- UI Elements: Fixed bug making docked EditorWindow hard to resize if their content near the borders react to MouseDownEvent
- UnityLinker: Prevent engine code stripping from removing the legacy input system module when any input magic methods are defined on MonoBehaviours
- Video: [Mac] Video-heavy project does not get successfully imported when launching the project in batchmode
