  Cleanup: Improve types used for sculpt undo attribute reference - AttrType instead of eCustomDataType - std::string instead of char array - std::nullopt instead of AttrDomain::Auto Pull Request: https://projects.blender.org/blender/blender/pulls/161313

  Fix #159075: UV tool settings reset on operator redo in mesh edit-mode Changes to UV sync-select, sticky & island selection would be reset when performing an operator that used undo/redo the repeat an action. This happened because the settings were tracked by undo but changing them didn't create undo steps. Resolve by adding a `PROP_FORCE_UNDO` flag, to allow individual properties to use undo even when the struct doesn't have `STRUCT_UNDO` flag set. Ref !161238

  Refactor: Texture Paint: Do seam copy serial, multi-threading makes it worse The additional overhead of gathering active groups and parallel foreach seems too much. Pull Request: https://projects.blender.org/blender/blender/pulls/161296

  Refactor: Texture Paint: Only do seam copy for affected image tiles Previously it would do the seam copy for the full image, regardless of how much was painted. Now we split the image into smaller 64x64 "seam tiles", and those are only processed if their source pixels were modified. Pull Request: https://projects.blender.org/blender/blender/pulls/161296

  Refactor: Texture Paint: Split seam copy per pixel data structure This improves performance by moving CopyPixelCommand to a separate array, so the main per pixel data structure is smaller and more cache efficient. The CopyPixelCommand is often only needed for a small subset of pixels near seams. The array with unused parts only exists temporarily during setup.

  Fix #160310: VSE: Strip animations don't play in sequencer-type scene strips This problem was originally resolved in 2019 with a372e5e426, by calling `BKE_animsys_evaluate_all_animation` when recursing into these strips. This worked at the time because it would iterate `main->scenes.first` and evaluate each scene's animdata including strip animation. However, it still did not fix it for prefetching, which uses a separate `bmain_eval`. In 2025 with bd61e69be5a, the scene animdata evaluation was removed inside of `BKE_animsys_evaluate_all_animation` which broke things again for the non-prefetch case. "Sync Scene Time" happens to fix it because it forces playback in the nested sequencer scene, which triggers animation evaluation. Fix for both prefetch and non-prefetch by just evaluating the scene we are about to recurse into. We no longer need to evaluate _all_ animation, e.g. masks do their own `BKE_animsys_evaluate_animdata` in `seq_render_mask` and other datablocks are dealt with similarly. The function was only ever used in this one edge-case, so we can remove it. There is one case that existing code does not cover: animation of compositor node trees inside the nested sequencer-type scene strip. This would require some more work, and can be deferred for a future 5.2 backport patch once there is a better plan for how to tackle evaluation in this case.

  Fix #161263: Handle empty bundle lists in Geometry Nodes Empty bundle lists stored with `SingleData::ForDefaultValue` could still behave as if they had one value during list iteration. This caused viewer logging to call `ensure_owns_direct_data()` on the default null `BundlePtr`, which then asserted in `ensure_mutable_inplace()`. Fix this by making `List<T>::foreach` and `foreach_for_write` return early for zero-sized lists. `SingleData` can store one value shared by all logical list elements, but when the logical list size is zero, that storage is only a placeholder and should not be visited. Null bundle pointers are also treated as trivially owning their data, since they do not reference any nested data. The regression test also exposed an existing memory leak in `SingleImplicitSharingData`. The stored default value was destructed, but its separately allocated storage was not freed. Free that storage during cleanup as well. A regression test was added for `SocketValueVariant::ensure_owns_direct_data()` on an empty bundle list.

  Fix: clarify Grease Pencil layer/material "pass_index" tooltips There is a "pass_index" for Grease Pencil layers, as well as one for Grease Pencil Materials. These are only used in certain modifiers (under the Influence panel) to restrict well their influence. These are **not** used in compositing. Note: there is a third "pass_index" (for Objects) that can be used in Cycles in a renderpass (or in EEVEE to some extend via the `Object Info` node) but that does not do anything for Grease Pencil objects. One could argue that could be removed, but better have that in a separate PR Part of #151561 Pull Request: https://projects.blender.org/blender/blender/pulls/161260

  Fix: Nodes: Various Add/Swap menu entries not in alphabetical order Shader Nodes - Split Bundle and Closure nodes in their own subsections. Geometry Nodes - Reorder certain nodes. - e.g. `Bone Info`, `Is Edge Smooth`, `Gamma`, `Implicit Conversion` - Create subsection for tool-specific `Geometry > Read` nodes. - e.g. `Active Element`, `Selection` - Create subsection for switch nodes. - Split the Bundle menu into multiple subsections. Compositor - Reorder `Mask to SDF` & `Implicit Conversion` - Create subsection for switch nodes. - Make order of `Utilities` submenus consistent with Geometry Nodes.

  Fix #62258: UI: Prevent overlap of Adjust Last Operation panel Redo panel overlaps in clip editor and image editor, this hides the scrubbing region and sample color bar below it. Added new flag `HUD_PADDING `. When it's set, move redo panel upwards by `UI_UNIT_Y`. New function `ED_area_hud_region_set_padding_flag` that basically handles the flag status.

  Fix #161185: USD export of a rigged nurbs surface is empty Followup to 4979e32129e5 The USD export also has a place calling `BKE_object_get_pre_modified_mesh` [which does not return anything for non.mesh objects]. Now use the `MeshCoerceForExport` introduced in 4979e32129e5 to make sure non-mesh objects like nurbs surfaces get a pre-modified mesh of their own on demand.

  Compositor: Add ID_RECALC_COMPOSITOR for scene IDs This patch adds a new scene ID reclac flag for compositor updates. The compositor previously relied on the ID_RECALC_NTREE_OUTPUT flag on the compositor node group ID, but this was not really correct for changes to the scene that happens to affect the compositor, for instance, a change of the compositor device. The upcoming layered compositor project will heavily rely on this new flag for things like compositor effect inputs, changes to the effects themselves and so on. But this patch already updates two places where the update was using ID_RECALC_NTREE_OUTPUT. Pull Request: https://projects.blender.org/blender/blender/pulls/161252

  Fix #137232: KDE+Wayland+Vulkan failure to restore cursor grab position Workaround problem With Vulkan on Wayland under KDE where the cursor restore location was ignored at times (typically under load). Resolve by applying the workaround proposed in KDE's bug tracker (issue 520910), calling set_cursor_position_hint then waiting until the commit is handled before destroying the "confined_pointer" object. The method of polling for the commit to be applied follows SDL-3.4's `Wayland_GLES_SwapWindow`. Ref !161244
