About Blender LTS
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 latest stable version, will be regularly ported over to active Blender LTS releases.
