Blender LTS

Introducing a Long-term Support program

Overview

The Blender LTS program is aimed at ensuring that long-lasting projects can be executed using a stable Blender version, which will provide critical fixes throughout a 2-year time span. The LTS version will not have any new features, API changes or improvements. Any critical fix that is applied to the 2.9 series will be regularly ported over to Blender 2.83 LTS. Learn more.

The LTS program is currently being tested. More information is available on code.blender.org.
