**Added**

* Added support for generating and logging in to coherence Cloud using a one-time code. This can be used for recovering lost accounts, and for logging in to the same account with a new device.
* Added the ability to log in to coherence Cloud using a Steam, Epic Games, PlayStation, Xbox, Nintendo account, or a JSON Web Token (JWT).
* Added ability to change coherence Cloud username, password, email, display name and display image.
* Added ability to get all coherence Cloud account information.
* Added ability to link multiple authentication methods to the same coherence Cloud account.
* Support for launching RS with host authority options for restricting entity creation to host or Simulator.
* Support for creating Replication Server (RS) rooms with host authority options for restricting entity creation to host or Simulator.
* Support for connecting to an RS as a host in Worlds or Rooms.
* BakeConditional attribute for controlling type networking via scripting define symbols.
* CoherenceGlobalQuery component to create queries on Simulators for other Clients.
* Toggle to set a CoherenceSync object as global so it can be visible to global queries.
* Max Overshoot Allowed setting in interpolation settings.
* New simplified coherence Cloud user management API accessible via the User class.

**Changed**

* **Multi-Room Simulators are deprecated**, and will be completely removed in the future.
* Renamed 'CoherenceSync Objects' to 'Networked Prefabs'.
* Hub: Renamed 'Overview' to 'Learn' (renders 'Welcome').
* Hub: Renamed 'coherence Cloud' to 'Cloud'.
* Hub: Renamed 'Scene' to 'Quick Start'.
* Hub: Removed 'Links', 'Baking' and 'GameObject'.
* Hub: most tabs have been revisited, with simplicity and usability in mind.
* Hub: tabs can offer 'Online Resources' section.
* Installs and updates open Hub on the 'Learn' tab instead of 'Welcome' window.
* MenuItem: 'Welcome' removed.
* MenuItem: 'coherence Hub' renamed to 'Hub'.
* Removed the dialog box that pops up the first time you assign a non-transferable Prefab to the CoherenceBridge's Client or Simulator connection Prefab slot. A warning is now shown underneath with a 'Fix' button.
* Prefab Variants no longer automatically pruned for missing or leaked references (use Prune button on Configure window if needed).
* Re-ordered Simulator build warnings and errors logically.
* Removed information panel on local Simulator builds because the `COHERENCE_SIMULATOR` symbol is automatically included when a local Simulator is built.
* Removed Reflection Mode. **Baking is now a requirement**.
* Reworked Settings window.
* Reworked the Play Mode panel (that tracks authority and persistence) on the CoherenceSync inspector.
* Room, Lobby, World and Matchmaking Connection Dialog samples now work regardless of whether or not CoherenceBridge has been configured to login to coherence Cloud automatically.
* CoherenceBridge disconnects on OnDestroy.

**Fixed**

* Nested Prefabs parented to a Prefab variant logged an error when fixing the instance after a sync group was added.
* Fixed an issue with the Interpolate On dropdown where "Nothing" was selectable.
* An error message was not displayed when an uninstalled Simulator build target option was selected.
* Addressable Prefabs automatically update their "Load Via" configuration when added/removed from the addressables registry.
* Fixed wrong error message shown when a PrefabSyncGroup component was applied to a non-root object.
* Prefab was not getting updated when "Fix Authority Type" button clicked in the CoherenceBridge's Client Connections section.
* Path to local sim build contained an extension if full-stops were used in the name on a non-Windows platform.
* Fixed an issue where the org dropdown list was really small if only one four-lettered organization was available.
* Made ToolkitArchetype duplicate Component detection rely on reference comparisons, so that it can't be broken by unusual IEquatable implementations.
* Space to display helper text for sharing a build's path was too small. Added an additional warning space to allow more room for the text.
* Removed usages of Task.Delay and fixed usages of ContinueWith for WebGL support.
* Improved readability of some warnings and errors that can occur when baking.
* Snapping after interpolation overshooting.
* Time desync after a frame freeze.
* Optimized the Networked Prefab windows to make it more performant for large amounts of Prefabs in the game.
* Removed layout warnings when opening the Editor with the Hub window visible.
* Issues when multiple Newtonsoft.Json installations are found in the project.
* Removed warning that was logged if AuthClient was disposed and there were no Prefs to be saved.
* Fixed an issue where a re-login to the cloud in the same session wouldn't work on MacOS.
* Fixed issue where NetworkPool could throw a NullReferenceException when exiting Play Mode in the Editor.
* Fixed an issue where warnings appeared after logging in to coherence cloud on a Mac.
