Try **Remove Original** again in your ARP setup; if orig/rep shared a collection, you should get object-only removal of the original instead of nuking both.

+
+Here’s what was added to `CHANGELOG.md` for **0.4.0** (mapped from the last five commits: bump → ARP → MigNLA activation → MigBBody manual meshes → Remove Original / ARP):
+
+| Commit | In changelog as |
+|----------|------------------|
+| `bump 0.4.0` | Release line + date |
+| `begin implementing ARP functionality` | **Added:** CharMig rig-family (ARP vs Rigify) and ARP-related migrator behavior |
+| `MigNLA: … repchar active before … animlayers` | **Changed:** MigNLA activates replacement before Animation Layers |
+| `add manual meshes to migbbody shapekeys` | **Added:** manual meshes for MigBBody shapekeys |
+| `fix rmorig ARP` | **Fixed:** Remove Original never drops a collection that still contains the replacement; Blender 5 parent checks |
+
+If any of the ARP or manual-mesh wording should match your UI labels exactly, say what you use in-panel and we can tweak the lines.

# Changelog
+## [0.4.0] - 2026-03-25
+
+### Added
+- CharMig: ARP (Auto-Rig Pro) support alongside Rigify (rig-family selector and related migrator behavior).
+- MigBBody shapekeys: include manually specified meshes in migration, not only auto-detected base body.
+
+### Changed
+- MigNLA: activate the replacement character before turning on Animation Layers, so AnimLayers apply without manually selecting rep first.
+
+### Fixed
+- Remove Original: when resolving which collection to delete, never remove a collection whose subtree still contains the replacement armature (avoids deleting both orig and rep when they share hierarchy); Blender 5 collection parent checks use collection names.
+
## [0.3.0] - 2026-03-13
