The Project Auditor package is now provided as an Editor module, and is no longer distributed as a package.
Editor
The Editor installer no longer bundles the Unity Services packages by default, which means they will be downloaded from the Unity Registry when you use them, instead of being cached directly inside the Editor installation.
Package Manager
Fixed "The text is cut off and doesn't fit for the "Enable Armv9 Security Features for Arm64" property". Changed "Enable Armv9 Security Features for Arm64 builds" to "Armv9 Security Features for Arm64".
Fixed crash on startup that could occur when the legacy Unity Analytics module is removed from the package manifest and code stripping is enabled for the build.
Fixed a race condition in the licensing client where the Editor would succeed to make the client acquire a floating license faster than it had finished loading licenses at startup, which would make it fail to pick up the new license.
Editor closes and does not reopen after applying changes to GPU Baking Device in Lighting window. Only the hub is opened.
Re-added support for Jetbrains Rider profiling, which had been temporarily removed with a recent security fix.
Fixed an "Unable to find style" warning that occurred when switching color blind mode on or off.
Fixed Highlights module and/or frame range selection resetting on domain reload.
Profiler
Fixed Library folder that was sometimes wrongly added to source control on a new project created from the Hub.

Version Control
This release directly addresses several high-severity security vulnerabilities, identified by Black Duck scans as CVE-2023-6349, CVE-2024-5197, and CVE-2025-5283, when applicable, through targeted code changes, without upgrading the underlying libvpx library. Due to compatibility and integration constraints, an upgrade to a newer libvpx version was not possible; instead, alternative fixes have been implemented within the current version to mitigate these specific issues.
VideoSecurity
Fixed "Autoconnect Profiler" build option. Autoconnecting sometimes raised the error "The message header is corrupted and for security reasons connection will be terminated." in the Editor.

EditorChangeUUM-125389
Changed the artifact dependency to ImportResultOutputID from ImportResultID. This created a more specific dependency that reduces the number of imports when an asset is changed. If the output of an import doesn't change, any asset with an artifact dependency to that asset is no longer reimported. As part of this change, the artifact database version was updated, which triggers a reimport of all assets in a project.
EditorChange
Improved the interaction between the EditorApplication play mode API and the PlayModeScenariosManager API to ensure more predictable behavior. Before a scenario runs, entering Play Mode via the EditorApplication API now resets the active scenario to default. While a scenario is active, attempts to alter the Play Mode state using the EditorApplication API are now prevented to avoid potential errors and undefined behavior.
