Known Issues in 2020.3.45f1
Asset Importers: The Editor hangs while opening a project when importing fbx assets (UUM-26676)

2020.3.45f1 Release Notes
- Multiplayer: Added Netcode for GameObjects 1.2.0.
Apple TV: Added: identifier for 3rd generation Apple TV 4K.
Editor: Added: Component.GetComponentInParent(Type t, bool includeInactive) method to match GameObject. (UUM-2199)
iOS: Added: identifiers for iPad models released in 2022.
Scripting: Added: New Object.FindFirstObjectByType() and Object.FindAnyObjectByType() functions added as potentially faster alternatives to Object.FindObjectOfType(). These new functions let you decide whether you must have the first (lowest InstanceID) object found or if any instance is adequate. In the latter case the function can be many times faster as no internal sorting is required. See the scripting documentation for both functions for more details.
Scripting: Added: New Object.FindObjectsByType() function added as a potentially faster alternative to Object.FindObjectsOfType(). This new function gives users the choice whether or not to perform the expensive sorting by InstanceID on the returned collection of objects rather than having it always performed wasting time when unnecessary. See the scripting documentation for Object.FindObjectsByType() and Object.FindObjectsOfType() for more details.
Version Control: Removed: Collab and its dependency from the package.
2D: Added proper manual URL for GridSelection. (UUM-20223)
2D: Fixed a crash when there is an invalid Sprite on a Tilemap and a TilemapRenderer tries to bind the invalid Sprite to a Sprite Atlas. (UUM-19275)
2D: Fixed rendering of GameObjects in a Tile Palette window when a Scriptable Render Pipeline is used. (UUM-22035)
AI: Fixed an issue that passage was blocked through seemingly valid polygons after an obstacle carved the NavMesh nearby. (UUM-8240)
Android: Fixed build failing when app bundle option is enabled and output file has no extension. (UUM-10941)
Android: PermissionCallbacks.DeniedAndDontAskAgain is no longer invoked on Android 11 and later. Use Denied instead on all versions. (UUM-20936)
Asset Bundles: Fixed issue where "Failed to decompress data" error occurs when loading bundle. (UUM-6639)
Asset Pipeline: Elided asset import paths using ellipsis on the import dialogue if the path length exceeds maximum text width. (UUM-3657)
Audio: Updated FMOD's FLAC from version 1.2.1 to 1.3.4. This fixes an issue identified by our application security team. (UUM-400)
Build Pipeline: Fixed crash when building ScriptableObject asset in Resources folder, where source filename did not match the class name. (UUM-21886)
Build Pipeline: Fixed static batching sorting to ensure deterministic build results. (UUM-11427)
DX12: Fixed a crash observed in e.g. HDRP sample project. (UUM-20176)
Editor: Camera relative culling options have been added to the Graphics section in Project Settings. This will potentially alleviate light popping issues due to lack of precision when the objects or lights are far from the origin. Enabling the camera relative culling setting for lights will potentially introduces issues for objects or lights that are far from the camera origin. (UUM-7551)
Editor: Fixed a memory leak which would manifest when loading then unloading scenes additively. (UUM-18684)
Editor: Fixed an Editor crash when calling API's to show modal dialogs while -drawRect is in progress. (UUM-2293)

Editor: Fixed an issue that undo skips a value when used on values with [CustomEditor]. (UUM-16740)
Editor: Fixed an issue that VideoPlayer.width and height return 0 instead of expected values. (UUM-1899)
Editor: Fixed an issue to ensure scene view outline render uses the attributed main texture property name rather than the default name. (UUM-20416)
Editor: Fixed case where SetParent allowed setting transforms as parents when they are persistent. (UUM-12399)
Editor: Fixed determinism issue with ModelImporter where the current scene root count affects import results. (UUM-1846)
Editor: Fixed layout serialization logic: we now discard views that are not properly initialized. (UUM-21599)
Editor: Fixed use-after-free in macos menu handling. (UUM-22680)
Editor: Improved error message when an incompatible mesh is used with skinning code. (UUM-13268)
Editor: OpenSSL updated to 1.1.1s. (UUM-18983)
GI: Cached the result of GetLightmapDecodeValues() to make it faster. (UUM-1943)
GI: Fixed an issue where Enlighten RTGI schedules material updates indefinitely when animating the emission color of an emissive mesh renderer. (UUM-10037)
GI: Fixed baked lighting on terrain holes and better performance. (UUM-1797)
