\[UUM-78767\] <https://issuetracker.unity3d.com/issues/unity-editor-restart-required-when-switching-to-web-platorm-in-build-profiles-window> - Graphics Optimization Systems: Shader errors in DXC when building an empty URP project for Windows platform on a MacOS machine ([UUM-78665](https://issuetracker.unity3d.com/issues/shader-errors-in-dxc-when-building-for-windows-platform-on-a-macos-machine)) - Lighting: Block compression leads to lightbaking artifacts in HDRP ([UUM-74735](https://issuetracker.unity3d.com/issues/lightmap-has-artifacts-when-generating-lighting)) - Physics 2D: A potential crash can happen when a 2D Physics contact is created and destroyed in the same simulation step. - SRP Core: \[URP 3D Sample\] Light rendering artifacts visible in Universal 3D Sample Template. It seems to be that Shader Graphs/Screen_Graph is causing the issue. Disabling objects with this material will no longer reproduce light artifacts.

(UUM-77329) - Android: Fixed an issue with native plugin being skipped for ARMv7 architecture if target CPU is not set.

(UUM-77692) - Asset Pipeline: Increased the integrity of the asset database to minimize the risk of corruping a library folder. It changes the way we flush in-memory data to the database internally.
Unfortunately this change might introduce a performance regression for users with spinning disk hard-drives. To accommodate this user group, we are introducing the command-line flag `sacrificeDBIntegrityForPerformance`, which you can use to opt out of this new behaviour and fall back to the way it has worked before.

(UUM-62419) - Editor: Restored the tooltip to the View Tool button in the Tools overlay within the Scene view. ([UUM-78214](https://issuetracker.unity3d.com/issues/tooltip-is-not-shown-when-hovering-cursor-over-view-tool-in-scene-view-tools-overlay)) - GI: Fixed an issue where shader variants with LIGHTMAP_ON that didn't declare DIRLIGHTMAP_COMBINED were stripped during player builds when using directional lightmapping.
