Blender 5.2.4 LTS is a maintenance release, and its focus is squashing crashes and freezes. The Blender team says it carries important bug fixes for the v5.2 Stable LTS branch.

On Steam, you can switch to that branch by right-clicking Blender in your library and choosing Properties. Then open the Betas tab and select v5.2 - Stable - Stable.

Crashes and freezes

  • Cycles Metal: a data race that could crash kernel compile threads is fixed.
  • A crash with the Delaunay Grease Pencil fill tool on an empty frame is gone.
  • Symmetrizing bones that have Action constraint animation no longer crashes.
  • A fatal crash or infinite freeze with a specific Curve to Tube node setup is fixed.
  • A Map Range node plugged into Blur no longer crashes Blender.
  • Geometry Nodes: a crash with a Bundle List in a simulation zone is fixed.
  • Cycles: a crash with bump from displacement combined with emission is fixed.
  • VSE: a freeze with text strips is fixed, along with a crash when reading or writing retiming keys on the wrong strip.
  • Copying a newly created scene with an unsynchronised view layer via libraries.write no longer crashes.

Editors and tools

  • UV Editor: the Fixed Subdivision grid offset and the partly drawn Pixel Grid overlay are fixed.
  • Graph Editor: Vector/Aligned handle pairs are possible again after regressing since 4.5/5.0.
  • NLA strip influence and strip time keyframe types can be changed from the interface again.
  • Auto masking cavity works again.
  • Text-box trackpad scrolling is fixed.
  • The new Flatten operator now copes with vertices and edges that have no faces attached.
  • Holes in the skin modifier’s result are fixed.
  • The “Generic Tool: Annotate” category shows up again in the key map editor.
  • Compositor: a wrong Matrix to Rotation conversion on the GPU is corrected.
  • Node Wrangler’s Reset Nodes no longer errors when the active node is None.
  • OpenEXR DWA compression no longer applies to non-colour data passes.

Grease Pencil and curves

  • Missing pressure curves for 5.2 are back.
  • The ‘duration’ and ‘end frame’ features are disabled, and ‘Duration’ is hidden from the Insert Blank Frame operator.
  • Several fixes make loading files with invalid Grease Pencil and Curves values safer.

Under the hood

  • Python’s certifi and pip are updated, and Brotli moves to 1.0.10.
  • A node group name is now escaped properly in a Python expression when swapping nodes.
