Blender 4.5 LTS: Core

Big Endian Support Deprecation

Blendfiles saved by Blender from a Big Endian platform will trigger a warning when opened. See that annoucement for details.

Linking & Library Overrides

• Linked IDs can now also be relocated, if they are not a dependency of any other linked data (PR#135936, 0eba8caaf9, 3fa35aa4ee).

Path Templates

Some file paths in Blender can now contain "template expressions" like {blend_name} and {resolution_x}, which get replaced by the values they reference when the path is used. (e0beb7afe6, documentation)

Currently this is only enabled on the Scene's render output path and the output paths of the compositor's File Output node.

Other

• Blender on Windows now shows a crash popup with recovery options (3ab65cff04).
• Dependency graph building is slightly faster (up to 18%) when there are many data-blocks (d1df97bd48).
