- Android: Improved support for playing video in addressables and AssetBundles. Compressed and in-memory bundles are now supported on Android 9 and newer devices.
- Animation: Verified Animation Rigging package version 1.0.3.
- Asset Pipeline: Added Safe Mode for startup, which gives you the option to avoid asset importing when there are script compilation errors.
- Asset Pipeline: Added two new properties to the Asset Pipeline:
- AssetDatabase.GlobalArtifactDependencyVersion
- AssetDatabase.GlobalArtifactProcessedVersion.
- Asset Pipeline: Enabled consistency checking of assets using -consistencyCheck on the command-line and when force reimporting through the Project window.
- Editor: Added a -version argument to command-line inputs that prints the current version of Unity to the console.

- Editor: Added button Enable debugging to all projects to the dialog box C# Debugger Attached, and made text more descriptive.
- Editor: Added support for a Root Namespace field in Assembly Definition files. New scripts created inside Unity have a namespace in the default template if it is set in the corresponding Assembly Definition file (or for non-Assembly Definition file scripts, the Project Settings > Editor > Project Root namespace).
- Editor: Added support for importing texture arrays (Texture2DArray) and volume textures (Texture3D) from "flipbook" image layouts. To use this, open the Texture Importer and see the Shape setting.
- Editor: Added support for Roslyn reference assemblies. Unity skips compilation of assembly references if the metadata for the modified assembly does not change when compiling scripts for the editor. Reference assemblies are enabled by default; to disable them, open the Player settings and disable Use Reference Assemblies.
- Editor: Added the ability to optionally drag all the edges from one port to another at the same time.
- Editor: Added the ability to toggle GraphView snap lines on or off in Preferences. If enabled, GraphElements in GraphViews align with one another when moved. If disabled, GraphElements move freely.

- Package Manager: Added the Preview Packages in Use dropdown menu.
- Package Manager: Added changelogUrl and licensesUrl as optional properties that can be specified in the package.json of a custom package. If specified, the auto-generated changelog and license links will be replaced with custom URLs.
