      redownload).

+   -  :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 :term:`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).
+
+   -  Add support 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 the
+      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 the LZO
+      library, that was brought back after a (now reverted) removal.
+
+   -  `python3-jsonschema-specifications <https://pypi.org/project/jsonschema-specifications/>`__:
+      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 the Meson build-system for Python packages.
+
+   -  `python3-pyproject-metadata <https://pypi.org/project/pyproject-metadata/>`__:
+      a class to handle PEP 621 metadata, and a dependency for
+      ``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
+      to the Rust rpds crate, and a runtime dependency for ``python3-referencing``.
+
+   -  `python3-sphinxcontrib-jquery <https://pypi.org/project/sphinxcontrib-jquery/>`__:
+      a Sphinx extension to include jQuery on newer Sphinx releases. Recent
+      versions of ``python3-sphinx-rtd-theme`` depend on it.
+
+   -  `python3-yamllint <https://github.com/adrienverge/yamllint>`__: a linter
+      for YAML files. In U-Boot, the ``binman`` tool uses this linter to verify the
+      configurations at compile time.
+
+   -  ``systemd-boot-native``: a UEFI boot manager, this time built as native to
+      provide the ``ukify`` tool.
+
+   -  `utfcpp <https://github.com/nemtrif/utfcpp>`__: a C++ library to handle
+      UTF-8 encoded strings. It was added as a dependency for ``taglib`` after
+      its upgrade to v2.0.

 -  BitBake improvements:

+   -  Add support for :term:`BB_LOADFACTOR_MAX`, so Bitbake can stop running
