+ - :term:`RPMBUILD_EXTRA_PARAMS`: support extra user-defined fields without
+ crashing the RPM package creation.
+
+ - :term:`OPKG_MAKE_INDEX_EXTRA_PARAMS`: support extra parameters for
+ ``opkg-make-index``.
+
+ - :term:`EFI_UKI_PATH`, :term:`EFI_UKI_DIR`: define the location of UKI
+ image in the EFI System partition.
+
- Architecture-specific enhancements:
+ - ``genericarm64``: a new ``MACHINE`` to represent a 64-bit General Arm
+ SystemReady platform.
+
+ - Add Power8 tune to PowerPC architecture.
+
+ - ``arch-armv9``: remove CRC and SVE tunes, since FEAT_CRC32 is now mandatory
+ and SVE/SVE2 are enabled by default in GCC's ``-march=armv9-a``.
+
- Kernel-related enhancements:
+ - The default kernel is the current LTS (6.6).
+
+ - Added suport for ``genericarm64``.
+
- New core recipes:
+ - `bmaptool <https://github.com/yoctoproject/bmaptool>`__: a tool for
+ creating block maps for files and flashing images, being now under Yocto
+ Project umbrella.
+
+ - ``core-image-initramfs-boot``: a minimal initramfs image, containing just
+ udev and init, designed to find the main root filesystem and pivot to it.
+
+ - `lzlib <https://www.nongnu.org/lzip/lzlib.html>`__: a data compression
+ library that provides LZMA compression and decompression functions.
+
+ - `lzop <https://www.lzop.org/>`__: a compression utility based on LZO
+ library, that was brought back after a (now reverted) removal.
+
+ - `python3-jsonschema-specifications <https://pypi.org/project/jsonschema-specifications/>`__:
+ the support files for JSON Schema Specifications (meta-schemas and
+ vocabularies), added as a new dependency of ``python3-jsonschema``.
+
+ - `python3-maturin <https://github.com/pyo3/maturin>`__: a project that
+ allows building and publishing Rust crates as Python packages.
+
+ - `python3-meson-python <https://github.com/mesonbuild/meson-python>`__: a
+ Python build backend that enables Meson build-system for Python packages.
+
+ - `python3-pyproject-metadata <https://pypi.org/project/pyproject-metadata/>`__:

+ ``python3-meson-python``.
+
+ - `python3-referencing <https://github.com/python-jsonschema/referencing>`__:
+ another dependency of ``python3-jsonschema``, it provides an
+ implementation of JSON reference resolution.
+
+ - `python3-rpds-py <https://pypi.org/project/rpds-py/>`__: Python bindings

+
+ - `python3-sphinxcontrib-jquery <https://pypi.org/project/sphinxcontrib-jquery/>`__:

+ versions of ``python3-sphinx-rtd-theme`` hardly depend on it.
