Blender News

Blender Foundation and the online developer community proudly present Blender 4.4!

Featuring artwork from Flow, the Oscar-winning film entirely made in Blender. Read the user story with director Gints Zilbalodis.



Blender 4.4 focuses on stability, with over 700 issues tackled through the “Winter of Quality”. Read more on the Code blog.

Major improvements include a new way to pack multiple data-block animations into one Action using Slots, a full CPU rewrite for the Compositor, Grease Pencil stabilization and feature parity, Video Sequencer text editing improvements, and, as always, better performance and a more refined user interface to enhance the user experience.

Watch the video summary on Blender’s YouTube channel.

This work is made possible thanks to the outstanding contributions of the Blender community, and the support of the over 7300 individuals and 35 organizations contributing to the Blender Development Fund.

Happy Blending!
