Noticed that in Blender 4.1 when you rename object, e.g. to "Cube" and this name is already used, object's name is set to "Cube.001".

In Blender <4.1 it was setting object's name to "Cube" either way and was changing name for other object to "Cube.001". See example below that you can run in default Blender scene.

It's not really a big deal, just haven't found anything related in release notes and wanted to put it out there as it might affect something else.

import bpy

cube = bpy.data.objects["Cube"]
light = bpy.data.objects["Light"]
light.name = "Cube"

# Blender <4.1 Cube, Cube.001
# Blender 4.1+: Cube.001, Cube
print(light.name, cube.name)

Hi, this was an intentional change, see: #119139 / 195bb4f8f5
Now renaming ID is consistent with other areas (eg: renaming vgroups, shapekeys, etc.)

t was setting object's name to "Cube" either way and was changing name for other object to "Cube.001"

It was a bit "hit and miss" case in earlier versions, see: #115192
