- Final version updated to 2019.3.10
What's New in version 2019.1:
Editor workflow & performance improvements. 2019.1 marks the start of the newest tech cycle, with lots of new features and functionalities. It increases your potential iteration speeds when developing for Android, improves your workflow and gives you more control over the editor.
Incremental Garbage Collection (Experimental)
In Unity 2019.1 we’re introducing the Incremental Garbage Collector as an experimental alternative to the existing garbage collector for projects targeting the Universal Windows Platform. The Incremental Garbage Collector is able to split its work into multiple slices. Instead of having a single long interruption of your program’s execution to allow the GC to do its work, you can have multiple, much shorter interruptions. While this will not make the GC faster overall, it can significantly reduce the problem of GC spikes breaking the smoothness of animations in your project by distributing the workload over multiple frames.
What to expect from a beta
As with any beta program, you’ll have early access to new features and will be able to assist in the final steps of their development. That means you’re likely to experience Unity as less stable than a final version.
The beta phase begins once all scheduled major features have been included and a quality baseline has been established. Several beta versions will be made available during this phase and quality will improve with each iteration.
NOTE: Remember to backup your project before running it in a Unity beta.

New 2019.1.0b2 Entries since 2019.1.0b1
- XR: Updated Google VR to version 1.18.0.
- Terrain: Added new callback APIs to monitor the terrain texture changes:
- TerrainAPI.TerrainCallbacks.textureChanged These callbacks tell both the rect region being changed and if the change is CPU synchronized or not (i.e. GPU only).
- Terrain: Added new TerrainData APIs for easier modifying the terrain textures:
- TerrainData.CopyActiveRenderTextureToTexture These two may be used for copying the content of the active RT into the terrain textures, optionally delaying the CPU synchronization, for instance at the event of mouse move in the middle of painting.
- TerrainData.DirtyTextureRegion These two may be used alternatively to the two functions above if the user directly changes the GPU resources by other means.
