4.6.12 (2026-04-23)
~~~~~~~~~~~~~~~~~~~

Fixed
^^^^^

* Fixed CI failures in Theia-based observation tests where ``from transformers import AutoModel``
raised ``ValueError: Unable to compare versions for packaging>=20.0: need=20.0 found=None`` when
Isaac Sim's bundled ``packaging`` install was missing ``dist-info`` metadata. Pinned
``packaging>=20.0`` in ``source/isaaclab/setup.py`` so pip reinstalls the package with proper
metadata during setup.
