+ - The ``mesa`` recipe now declares two new :term:`PROVIDES` for Vulkan
+ and OpenCL ICD. These virtual provider are respectively named
+ ``virtual-opencl-icd`` and ``virtual-vulkan-icd``.
+
+ - ``mesa-demos``: split info tools to a separate package ``mesa-demos-info``.
+
+ - ``vte``: skip :ref:`ref-classes-gobject-introspection` with Clang on Arm,
+ as it caused build failures.
+
+ - ``shadow``: Increase the maximum group name length from 24 to 32 (default
+ value provided by upstream recipe, was previously hardcoded to 24).
+
+ - ``udev-extraconf``: Speed up the ``mount.sh`` script by passing the block
+ device of interest to ``blkid`` when getting partition label names.
+
+ - ``piglit``: enable OpenCL support if ``opencl`` is part of the
+ :term:`DISTRO` features.
