Release Notes for 517

Added a lint rule suggesting when a global that is never read before it is written can be turned into a local.

The Find/Replace window will no longer keep results in scripts highlighted when it is hidden.

Fixed an issue where the pivot could be dragged and pivot indicators were shown when selecting multiple objects while using the Pivot Editor.

Add public/private toggle for editing audio assets on Asset Configuration.

Added a check to detect whether regular users impersonate admin when launching studio.

Add new APIs for loading font assets from cloud, with support for multiple different weights.

Fixes an issue where the Toolbox/Asset Manager audio preview could get stuck on the loading state.

Added default initial user agent for WebView2.

Fix a soundness bug around adding optional properties to sealed tables.

Fix occasional crashes with table type unification due to iterator invalidation.
