2.1.6

Version 2.1.6 is a hotfix release addressing crashes on Blender exit due to keymap conflicts and a recurring error in the depsgraph update handler. It also includes minor UI improvements to the Rename section.

Fixes

• #236: Fixed an error in the PostChange depsgraph update handler when bpy.context.selected_objects is unavailable — occurring when enabling or disabling another addon while Simple Renaming is active.
• #235: Fixed a crash on Blender exit when another addon's keyboard shortcut conflicts with Simple Renaming's keymap in Blender 5.1.

Improvements

• #237: Improved descriptions and tooltips in the Rename section of the panel.

2.1.5

Version 2.1.5 brings full Blender 5.1 compatibility, major performance improvements for large scenes, and new renaming targets including Node Groups and Point Clouds. The release also includes a range of quality-of-life additions such as case transformation operators and extended variable support, alongside numerous bug fixes and stability improvements.
Features

    #218: Major performance overhaul for large scenes. Collection lookups, owner-object resolution, variable replacement, numeration uniqueness checks, and regex compilation have all been rewritten from linear or quadratic algorithms to O(1) lookups. Scenes with 500+ objects, many bones, modifiers, or collections will rename significantly faster.
    #224: Added Node Groups as a new renaming target.
    #214: Added support for renaming Point Cloud objects (Blender 4.5+).
    #210: Added case transformation operators (UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase) under a new Case section in the panel.
    #206: Added support for \U, \L, and \E regex modifiers in Search and Replace for case transformations.
    #212: Extended the @o variable to additional renaming targets: materials, UV maps, bones, modifiers, and shape keys.
    #228: Added an "Also Rename Data" option in preferences that automatically renames linked data-blocks (e.g. mesh, curve, light data) to match the object's new name.
    #197: Extended UV map renaming with support for renaming by index, renaming the active UV set, and batch renaming across multiple objects.

Fixes

    #195: Fixed renaming bones in Edit/Pose mode breaking drivers that reference those bones.
    #204: Fixed a preset appearing twice in the suffix/prefix by type popup.
    #205: Fixed crash on exit on macOS.
    #207: Fixed batch renaming of bones not working when triggered from the Outliner.
    #209: Fixed an AttributeError occurring in Blender 5.0.
    #211: Fixed a Python error caused by a backslash character in object names.
    #215: Fixed an error in "Search and Select" for bones when a matching name is found.
    #217: Fixed crash on exit in Blender 5.1.
    #219: Fixed crash when attempting to rename read-only attributes (e.g. mesh position).
    #222: Fixed numeration incorrectly restarting per object when renaming shape keys, vertex groups, UV maps, color attributes, and attributes.
    #225: Fixed crash when renaming objects in contexts without an active selection.
    #226: Fixed error when batch-renaming shape keys on a selection where some objects have no shape keys.
    #227: Improved keymap reliability by switching to active-context key binding.
