Possibly breaking changes
-------------------------

(none known)

New features
------------

* commit f80d96b15978 "libdt: add support for barebox,storage-by-uuid" added
  support for specifying barebox-state backend nodes in the device tree using
  the 'barebox,storage-by-uuid' compatible. The similarly-named Barebox driver
  looks for a storage device matching the given UUID, and when found registers a
  new device for it. This makes it possible to use GPT and MBR partitions as
  state backends without re-stating their respective partition tables in the
  device tree.

* commit bfa8e8eab135 "state: automatically find state.dtb in the ESP"
  implemented auto-detection of device trees on the EFI System Partition in
  /boot or /efi (the usual ESP mount points on most Linux distributions).

* barebox-state can now auto-detect state partitions on GPT if they have the
  Partition Type GUID 4778ed65-bf42-45fa-9c5b-287a1dc4aab1, which corresponds to
  a feature merged in Barebox v2023.07.0 (see commits leading up to
  <https://git.pengutronix.de/cgit/barebox/commit/?id=776714d9570253c46635>).
  - commit 2bab30b7d653 "libdt: add of_property_write_strings support"
  - commit c4ea02e5fb6e "libdt: generalize of_find_device_by_uuid for scoped lookup of all UUIDs"
  - commit 7de908382bed "libdt: fix of_get_devicepath looking up sibling if device unavailable"
  - commit 03a6d0146f5a "state: backend: direct: open block device in read-only mode if possible"
  - commit 86233cfe9ba5 "libdt: factor out u64 sysattr parsing into helper"
  - commit c458361777ab "libdt: drop broken if-branch"
  - commit cff3f1c19d78 "libdt: factor out __of_cdev_find helper"
  - commit 7a71beff497e "libdt: use block device partition instead of parent if found"
  - commit 72970a627990 "state: align with barebox use of of_cdev_find"
  - commit 5059165acd2b "libdt: use of_find_device_by_uuid for partuuid lookup"
  - commit b32cb1c15c42 "state: allow lookup of barebox state partition by Type GUID"

* commit 0976c48731ef "state: add option to lock device node" implemented
  locking the device node directly via flock() in the barebox-state tool instead
  of writing a lock file to the /run directory. This helps on systems that don't
  have a world-writeable /run. Currently the behaviour is disabled by default
  and can be enabled by the ./configure --enable-lock-device option and the
  'lock-device' option in meson.

* Meson was added as a build system. The support is currently experimental, but
  the plan is to phase out autotools in the future, but for now the old way of
  building the project will stay in place. See the updated instruction in the
  README for how to build dt-utils and run the new unit tests.
  - commit bc6e5d24916f "Add meson as build system"
  - commit 4e7ad815b856 "meson: options: use defaults of type boolean for boolean options"
  - commit 6dc8b1a948cf "meson: set optimization level to -O2 by default"
  - commit fc97420e830c "Makefile: include meson files in the dist tarball"

* There is now an initial set of unit tests, see the README on how to run them.
  - commit e5c524875a91 "meson: add simple integration test"
  - commit be44af10aa91 "libdt: add CONFIG_TEST_LOOPBACK"
  - commit 69a223619e28 "test: add barebox-state loop block device tests"
  - commit 885bb2feac99 "test: add test case with non-existent /dev/file"

* All files now have machine-readable license and copyright information, and the
  project conforms to the REUSE specification (see <https://reuse.software/>).
  You can build a Software Bill of Materials in SPDX format by running the
  'reuse spdx' command.
