The Blender Foundation has released the first update since Blender 4.3 came out at the end of last month, introducing Geometry Nodes upgrades, a rewritten Grease Pencil, Light Linking for Eevee, and several other features.
Blender 4.3.1 includes 95 bug fixes, addressing multiple crashes, problems with Expansions not installing or working correctly, tool fixes, particularly for Grease Pencil, and functionality breaking in files saved in older versions or not importing properly into 4.3, along with many other improvements.
As always, it's highly recommended to update. See the full list of changes here, and if you're not familiar with the features of Blender 4.3, watch the official recap:
