Compatibility
Blend Files
- The mesh format changes from previous versions are now included in the Blender file format.
- Blender 3.6 LTS can read files saved with 4.0, but earlier versions cannot.
- Blender 3.6 LTS will save meshes in a format compatible with older versions of Blender, so it can be used as conversion tool if needed.
- See the section in the Python API section for more details.
- The new blendfile compatibility policy (#109151) has been implemented (see PR #110109).
- Unused linked data is not kept anymore when saving and re-opening .blend files. See the core page for details.
Graphics Cards
- The minimum required OpenGL version has been increased to 4.3 for Linux and Windows. (3478093183)
- On macOS only Metal is supported now, and the OpenGL backend has been removed. A GPU with Metal 2.2 support is required. Intel Macs without an AMD GPU require a Skylake processor or higher. (cdb8a8929c)
- Due to driver issues, support for Intel HD4000 series GPUs has been dropped.
