Release 1.12 (development)
--------------------------
.. rubric:: Enhancements
* Add a ``min-bundle-version`` using SemVer format in ``system.conf``.
This causes RAUC to reject bundles with an older version. (by Johannes
Schneider)
* Avoid modifying the input directory during ``rauc bundle`` by using a
hard-linked copy.
For simplicity, we abort on anything in the input directory which is not a
regular file.
If someone relies on the old (undocumented) behavior of including directories
and symlinks in the bundle, please contact us.
* Allow configuration of additional mkfs options per slot using
``extra-mkfs-opts=<options>`` in ``system.conf``. (by David Robertson)
* Improve messages printed when aborting ``rauc install`` with Ctrl+C.
* Add the manifest build value to the hook execution environment. (by Heiko
Thiery)
* Add the bundle format to the ``rauc info`` shell and JSON formatters. (by
Peter Korsgaard)
* Add a systemd `journald message catalog
<https://www.freedesktop.org/wiki/Software/systemd/catalog/>`_.
* Allow plain bundles on ntfs3 mounts.
* Add contrib script to demonstrate how to get the CMS data from a bundle.
.. rubric:: Bug fixes
* Fix handling of slot installation skipping with global slot status and add a
test case.
* Fix PKCS11 URI handling in ``system.conf``. (by David Hollister)
* Fix block-hash-index cache by not cleaning the slot's data directory during
installation.
This avoids redundant slot scans to find reusable blocks during installation.
* Fix out-of-bounds reads in bootchooser backends.
* Fix some memory leaks in the NBD helper, D-Bus service, CLI and tests.
* Fix logging of the BUNDLE_HASH and SLOT_BOOTNAME values in the booted event.
* Fix double close of output file descriptor when using UBI volumes with
casync. (by Tim van der Staaij)
* Add missing "PRIORITY" field in event log messages.
* Improve NBD helper shutdown error handling.
.. rubric:: Testing
* Replace sharness with pytest.
This will make it easier to write and maintain complex test cases.
* Execute tests for ARMv5/7/8 and i386 using QEMU and multi-arch containers.
* Enable address sanitizer for all remaining tests.
* Enable undefined behavior sanitizer in CI.
* Run faketime tests only if it works. (by Uwe Kleine-König)
* Fix faketime when running under qemu-test.
* Update GitHub Actions to current versions.
* Fix coverage collection from the NBD helper in qemu-test.
* Update the kernel used in qemu-test to 6.6.36.
.. rubric:: Code
* Refactor manifest checks.
This makes it easier to reject invalid configurations during bundle creation.
* Add logging of build configuration at debug level.
This should help when analyzing bug reports.
* Ignore SIGPIPE to handle broken pipes explicitly.
* Add a helper to simplify GBytes access from OpenSSL.
* Refactor shell formatting for ``rauc status`` and ``rauc info`` to prepare
for consolidation with hook/handler environment setup.
* Allow declarations after statements.
.. rubric:: Documentation
* Improve reference sections for ``system.conf`` and the manifest by indicating
default values and fixing inconsistencies.
* Add missing reference documentation for image variants.
* Fix some typos. (by Gaël PORTAY and Michael B. Sumulong)

PORTAY, Heiko Thiery, Jan Lübbe, Johannes Schneider, Michael B. Sumulong, Peter
Korsgaard, Tim van der Staaij, Uwe Kleine-König
Release 1.11.3 (released Mar 15, 2024)
--------------------------------------
.. rubric:: Bug fixes
* Fix service startup when using symlinks in ``system.conf`` and ``root=`` in
the kernel commandline.
Systems using ``rauc.slot=<bootname>`` or ``bootchooser.active=<bootname>``
are not affected.
Contributions from: Enrico Jörns
Release 1.11.2 (released Feb 28, 2024)
--------------------------------------
.. rubric:: Bug fixes
* Fix 'rauc info' when used with streaming.
* Fix streaming helper shutdown when used with 'rauc info'.
This avoids a 'nbd server failed' message.
* Fix handling of streaming request retries.
* Remove a redundant event log message when trying to install an encrypted
bundle with an unencrypted manifest.
Contributions from: Enrico Jörns
Release 1.11.1 (released Jan 15, 2024)
--------------------------------------
.. rubric:: Bug fixes
* Ensure that only bootable slots can be marked with ``rauc staus mark-*``.
* Fix boot detection when using the ``rauc.external`` kernel command-line flag.
* Fix compatibility with OpenSSL 3.2 when using the ``codesign`` certificate
purpose.
* Fix a double free when trying to install two bundles using casync without a
service restart. (by Arseniy Lartsev)
.. rubric:: Testing
* Run service tests only when running as root.
.. rubric:: Documentation
* Improve description of current pre-install hook implementation.
Contributions from: Arseniy Lartsev, Enrico Jörns, Jan Lübbe
Release 1.11 (released Dec 20, 2023)
------------------------------------
.. rubric:: Enhancements
* Send :ref:`additional information as HTTP headers
<sec-additional-http-headers>` to the server on the first streaming request
(if enabled in the config).
* Add persistent system status information to detect reboots using the kernel's
``boot_id``.
* Add an ``--ignore-image=<slotclass>`` option to keep images as they are when
using ``rauc convert``.
This can be used to exclude some images (such as bootloaders) from the casync
conversion.
* Create :ref:`links for active slot devices <sec-run-links>` in
``/run/rauc/slots/active``.
This should avoid the need for parsing 'rauc status' output in some cases.
* Expose transaction ID to hooks during installation. (by Zygmunt Krynicki)
* Add support for ``get-current`` to the custom bootloader backend. (by Angelo
Compagnucci)
* Implement ``resign`` and ``replace-signature`` for encrypted bundles.
* Explicit ``rauc status`` output when no slot is activated (instead of
printing ``null``).
* Detect runtime config file change and warn in the service log.
* Improve various warning and error messages to better guide users. (by
Angelo Compagnucci and others)
* Remove autotools build system.
Support for meson was added in 1.9 and supported in parallel to autotools
until 1.10.1.
* Add log events for slot update, start/end of an installation, good/bad/active
marking and boot/service restart.
For an overview over the event logging framework in RAUC and its purpose, have
a look at :ref:`sec-advanced-event-log`.
.. note::
We don't consider the details of the new log events fixed yet, so please use
them as a preview and for testing.
In a future release, they will be documented in a `journald message catalog
<https://www.freedesktop.org/wiki/Software/systemd/catalog/>`_.
.. rubric:: Bug fixes
* Fix invalidation of slot status information during installation.
* Fix ``--no-verify`` for ``rauc resign``, to allow omitting the keyring.
* Fix installation of manual page when using meson.
.. rubric:: Testing
* Improve coverage for sanitizer builds.
* Add support for fuzzing. (initial setup by René Fischer)
* Integrate RAUC into OSS-Fuzz.
* Add `asan` option to the ``qemu-test`` script to allow running with address
sanitizer.
* Optimize ``qemu-test`` startup.
.. rubric:: Code
* Introduce structured event logging.
* Introduce an internal API for using the existing status file for global
information (system status).
* Fix minor memory leaks.
.. rubric:: Documentation
* Improve introductory and image type sections.
* Document ``CONFIG_DM_CRYPT`` as a required kernel config option for encrypted
bundles. (by Angelo Compagnucci)
* Allow installing HTML user documentation (``-Dhtmldocs=true``) (by Emil
Velikov)
* Explicitly mention LGPL as the license for the project in the README.rst. (by
Roland Hieber)
* Update sphinx and dependencies.

Release 1.10.1 (released Aug 3, 2023)
-------------------------------------
.. rubric:: Bug fixes

Release 1.10 (released Jun 23, 2023)
------------------------------------
.. rubric:: Enhancements
* Print sizes in ``rauc info`` also in human-readable form.
* Add FTPS support for bundle download (only for use with casync, not for
streaming). (by Christian Meusel)
* Improve progress granularity to provide more realistic weighting of substeps.
* Add fine-grained progress updates during image copying and archive
extraction. (based on work by Lars Poeschel)
* Return manifest meta data in ``rauc info`` and via the InspectBundle D-Bus
method.
* Add new 'json-2' output format for ``rauc info`` that matches the
InspectBundle D-Bus method structure.
* Improve error message for failed boot slot detection.
* Allow exFAT as a local filesystem for plain bundles. (by Stefan Wahren)
* Add optional pre-check for verity bundles.
This is useful if the same bundle needs to be transferred and installed to
multiple systems in sync. (by Christian Hitz)
* Add support for custom variables in the system-info handler and pass them to
other handlers.
* Show a warning during bundle creation if no format is specified in the
manifest.
This should hopefully encourage migration to the verity format.
* Introduce an installation transaction UUID, which is stored in the slot
status.
This can be used to infer which slots have been updated by the same
transaction.
In a future release, this will be useful to correlate log messages.
* Use a shorter connect timeout for streaming to avoid waiting for 25 minutes.
.. rubric:: Bug fixes
* Fix some issues in the meson build support:
* missing man page installation
* missing dependency for tests on D-Bus header generation
* missing executable bit for D-Bus wrapper ``rauc-service.sh``
* Fix external mount point detection which could have caused a number of mounts
to be not detected properly.
* Fix double-initialization of context.
* Fix memory leaks (mainly in the test suite).
* Fix a confusing error message when using ``rauc extract`` with an existing
output directory.
* Fix building with musl by not using ``off64_t`` with
``_FILE_OFFSET_BITS=64``. (by Christian Hohnstaedt)
* Fix unintentional forwarding of full custom handler args (defined in
the manifest) to the ``system.conf``-defined handlers.
* Re-add missing ``--key`` argument (used to set the decryption key) to help
and man page.
.. rubric:: Testing
* Add Debian 'buster', 'bullseye' and 'testing' to test stable test matrix.
* Add test run with address sanitizer.
This currently uses a large part of the existing test suite.
.. rubric:: Code
* Refactor installation handling with the introduction of installation plans.
This also allows testing for invalid image/slot combinations earlier.
* Add a helper for atomic symlink updates.
* Refactor slot state determination and split from mount point updates.
Let slot state determination happen earlier and only once.
* Require at least glib 2.56.0 for ``g_ptr_array_find`` and ``g_autolist``.
Debian buster, Ubuntu bionic and Yocto dunfell have newer versions already.
* Refactor boot slot marking.
* Consistently initialize variables to avoid static checker warning. (by
b4yuan)
.. rubric:: Documentation
* Document some Linux distributions which provide RAUC packages.
* Document deprecation of the ``statusfile`` option. (by Ulrich Ölmann)
* Extend and fix documentation for the full custom handler.

Ölmann, b4yuan
Release 1.9 (released Mar 3, 2023)
----------------------------------
.. rubric:: Enhancements
* Add new InspectBundle D-Bus method, which takes the same bundle access options
as the existing InstallBundle method.
This makes it possible to inspect bundles stored on HTTP servers which need
authentication.
It returns information from the manifest as a nested dictionary (for now,
this is only ``compatible``, ``version``, ``description`` and ``build``), but
can be extended as needed.
(by Stefan Ursella)
* Add support for loading and storing metadata entries in the manifest.
They are not yet exposed to the user.
* Add a manifest hash value and expose it via ``rauc info`` and ``rauc status``.
This can be used to identify a specific bundle.
* Support configurable boot attempt counters for barebox (using
``boot-attempts`` in the ``system.conf``).
* Add meson as an alternative build system.
We intend to drop autotools in 1.10, unless there are good reasons to keep it
for longer.
As the tar archive generated by meson does not contain a configure script,
you may need to run autogen.sh to generate it.
To simplify the migration, we also provide a ``-autotools`` archive variant
which is generated using autotool's ``make dist`` (and does not contain the
meson build support).
* Abort earlier if the image is too large for the target slot.
* Add warnings for some configuration issues when using adaptive updates.
.. rubric:: Bug fixes
* Fix a NULL dereference error caused by images larger than the target slot. (by
Kevin Hsieh)
* Fix compatibility with libcurl when built without proxy support. (by Christian
Meusel)
* Do not invoke any target-related context setup steps if no config is required.
This avoids unnecessary checks and removes the misleading messages about
unresolved paths.
* Fix number format for bootchooser when using U-Boot. (by Christian Meusel)
* Fix handling of partitioned loop devices, which caused incorrect aborts
during installation.
* Fix error handling when attempting to encrypt plain bundles.
.. rubric:: Testing
* Improve robustness of dm-verity/-crypt test setup.
* Enable scan-build for tests in GitHub Actions.
* Handle floating point comparisons in tests better.
* Add a GitHub Actions workflow for CodeQL scanning as a replacement for LGTM.
* Run the cross architecture tests on Debian bullseye instead of buster.
.. rubric:: Code
* Move the ``-intermediate`` option to the subcommand level and update the
manual page.
* Improve error handling for invalid ``boot-attempts`` configuration.
* Fix some minor memory leaks.
.. rubric:: Documentation
* Document our :ref:`approach to bundle compatibility <sec-compatibility>`.
* Add links to public example integrations of RAUC into different build systems
and boards.
* Add an issue template and a SUPPORT.rst file.
* Improve the documentation on slot skipping with regard to streaming.
* Update README.rst with new features.

Stefan Ursella, Ulrich Ölmann, Uwe Kleine-König
Release 1.8 (released Sep 30, 2022)
-----------------------------------
.. rubric:: Enhancements
* Implement adaptive image updates based on block hash indices.
This works by adding an index file containing the hashes of each 4kiB image
block in the image to the bundle and then using this to check whether a block
is available locally during installation.
If that's the case, RAUC doesn't need to download this block.
Together with streaming, this means that only a small part of the bundle needs
to be downloaded as long as the changes are localized.
See the :ref:`documentation for details <sec-adaptive-updates>`.
* Add a slot type which provides atomic bootloader updates for SoCs (like the
Rockchip RK3568) which search for a valid image at multiple fixed offsets. (by
Matthias Fend)
See the :ref:`documentation for details <sec-raw-partition-fallback>`.
* Add a configuration option for additional arguments to pass to ``casync
extract``. (by Ludovico de Nittis)
* Add initial support for desync (an alternative casync implementation). (by
Ludovico de Nittis)
* Add support for a RAUC data-directory on a shared partition.
Unless otherwise configured, this is also used to store the central slot
status data.
See the :ref:`documentation for details <data-directory>`.
* Allow setting a passphrase for encrypted PEM files via the environment
(``RAUC_KEY_PASSPHRASE``). (by Marc Kleine-Budde)
* Ignore ``meta.<label>`` sections in the manifest.
The ``meta.<label>`` sections are intended to provide a forwards-compatible
way to add data to the manifest which is not interpreted by RAUC in any way.
Currently, they are just ignored when reading a manifest. In future releases,
they will be accessible via ``rauc info``, the D-Bus API and in
hooks/handlers.
.. rubric:: Bug fixes
* Avoid retrying on HTTP 404 errors during streaming.
* Improve error handling during loop device block size configuration. (by Ahmad
Fatoum)
* Fix handling of empty partitions for ``boot-mbr-switch`` slots.
* Do not attempt to take ownership of plain bundles if running as non-root.
* Unmount seed slots if casync fails during installation. (by Jonas Licht)
* Add missing test files to the dist .tar.xz. (by Uwe Kleine-König)
.. rubric:: Testing
* Refactor the statistics code to make it useful for testing as well.
* Replace Ubuntu 21.10 test container with 22.04
* Add more tests for casync conversion and installation.
.. rubric:: Code
* Log error messages from CURL for failed streaming requests.
* Add doctype to D-Bus XML specification. (by Morgan Bengtsson)
* Improve error messages related to bootloader communication.
* Improve error reporting for directory creation failures.
.. rubric:: Documentation
* Document that the required kernel features can be configured as modules as
well.
* Document how to load and store the GRUB environment from a shared partition.
* Document some best practices regarding storage partitioning.
* Explain differences between casync and streaming & adaptive updates.

Bengtsson, Ulrich Ölmann, Uwe Kleine-König
Release 1.7 (released Jun 3, 2022)
----------------------------------
.. rubric:: Enhancements
* Add support for streaming installation from a HTTP(S) server for bundles in
``verity`` and ``crypt`` formats.
This avoids the need for a temporary bundle storage location and prepares for
more efficient *adaptive* (originally *incremental*) updates.
See the :ref:`documentation for details <http-streaming>`.
* Add support for bundle encryption (``crypt`` format).
This is useful when bundles contain confidential data and are not otherwise
protected during transport (for example, via HTTP, unauthenticated HTTPS or
USB storage).
See the :ref:`documentation for details <sec-encryption>`.
* Optionally allow verification with partial chains.
If enabled, RAUC will also treat intermediate certificates in the keyring as
trust-anchors, in addition to self-signed root CA certificates. This makes it
possible to trust only one (or more) sub-tree(s) in a larger PKI.
See the :ref:`documentation for details <allow-partial-chain>`.
* Divert log messages to stderr, which is useful for machine readable output
(``rauc status --output-format=json``).
This is only enabled when built with glib 2.68 or newer.
(by Ludovico de Nittis)
* Only allow the root step to report 100% progress. (by Steven Rau)
* Add the ``--trust-environment`` option to ``rauc extract`` and ``rauc
extract-signature``.
* Improve the error message printed on compatible mismatch.
.. rubric:: Bug fixes
* Don't enforce bundle exclusivity if the environment is trusted. (by Ludovico
de Nittis)
* Clean up error handling for 'rauc status'.
* Fix some memory leaks. (by Zygmunt Krynicki)
* Fix unintentional removal of existing bundles on error.
* Fix build error when PRIu64 is not defined. (by Fabrice Fontaine)
.. rubric:: Testing
* Make some tests conditional on the existence of the openssl binary.
* Access rauc.io instead of example.com.
* Explicitly use Python 3 in coverity checks. (by Thorsten Scherer)
* Add build tests on Ubuntu 21.10.
.. rubric:: Code
* Add some missing files to the dist tar.gz. (by Uwe Kleine-König)
* Change minimum glib version from 2.49.3 to 2.50, allowing use of g_autoptr
with the auto-generated DBus code.
* Use g_autofree/g_autoptr in more places.
* Use more specific error codes for device mapper error reporting.
* Prepare for incremental methods by adding an optional per-image manifest
option.
.. note::
Since the release of 1.7, it turned out that the name 'incremental' for this
functionality is confusing.
Accordingly, we decided to rename it to 'adaptive' for 1.8 and accept the
downside of not being able to benefit from compatibility with 1.7.
.. rubric:: Documentation
* Fix some broken internal links. (by Thorsten Scherer)
* Mention Buildroot support for RAUC. (by Thomas Petazzoni)
* Fix some typos. (by Bastian Krause and Michael Riesch)
* Clean up some inconsistencies between README and main documentation.
* Fix misleading rescue slot example. (by Sean Nyekjaer)
* Fix broken links to external pages. (by Bastian Krause)

useful for scenarios with strict limitations on how HSMs can be used. (by
Jean-Pierre Geslin)
* Implemented a ``rauc mount`` command to allow inspection of bundles without
extraction.
* Allowed omitting the image filename when using the ``install`` slot hook.
* Implemented support for extracting tar archives to jffs2 slots. (by Holger Assmann)
* Added option for the ``resign`` and ``info`` commands to ignore expired
certificates (``--no-check-time``). (by Michael Heimpold)
* Added option for the ``convert`` command to disable the concurrent access
checks for plain bundles (``--trust-environment``).
* Simplified usage of compressed SquashFS images with extensions as created by
OpenEmbedded. (by Omer Akram)

Contributions from: Enrico Jörns, Fabrice Fontaine, Jan Lübbe
Release 1.5 (released Dec 14, 2020)
-----------------------------------
.. note::
This version introduces the new ``verity`` bundle format (the old format is
now called ``plain``).
The ``verity`` format was added to prepare for future use cases (such as
network streaming and encryption), for better parallelization of installation
with hash verification and to detect modification of the bundle during
installation (CVE-2020-25860).
The bundle format is detected when reading a bundle and checked against the set
of allowed formats configured in the system.conf (see :ref:`sec_ref_formats`).
As the old ``plain`` format does not offer protection against modification
during the installation process, RAUC now takes ownership of the bundle file,
removes write permissions and checks for existing open file descriptors.
This is intended as a mitigation to protect against a compromised update
service running as a non-root user, which would otherwise be able to modify
the bundle between signature check and actual bundle installation.
See :ref:`sec_int_migration` for more details on how to switch to the
``verity`` format.
.. rubric:: Enhancements
* Add support for the ``verity`` bundle format. See the :ref:`reference for
details <sec_ref_format_verity>`.
* Support resolving the `root=PARTLABEL=xxx` kernel command line option. (by
Gaël PORTAY)
* Disable the unnecessary SMIMECapabilities information in the bundle
signature, saving ~100 bytes.
* Remove redundant checksum verification for source images during installation.
The RAUC bundle is already verified at this point, so there is no need to
verify the checksum of each file individually. (by Bastian Krause)
.. rubric:: Security
* Take ownership of bundle files if they are not owned by root and remove write
permissions. Then check that no writable file descriptors are open for the
bundle file (using the ``F_SETLEASE`` fcntl). This fixes CVE-2020-25860. See
the advisory for more details:
https://github.com/rauc/rauc/security/advisories/GHSA-cgf3-h62j-w9vv
.. note::
The https://github.com/rauc/rauc-1.5-integration repository contains examples
to simplify integrating the RAUC update into existing projects.
You can subscribe to https://github.com/rauc/rauc-1.5-integration/issues/1 to
receive notifications of important updates to this repository and of
integration into the upstream build systems.
.. rubric:: Bug fixes
* Fix install handler selection for *.img files for boot-* slots when used with
casync. (by Martin Schwan)
* Fix checking for unknown keys in the slot configuration.
* Fix some corner cases related to stopping the D-Bus daemon.
* Propagate error if unable to save manifest. (by Stefan Wahren)
* Apply `--handler-args` only during installation (and not during bundle
creation).
.. rubric:: Testing
* Ship `test/minimal-test.conf` to fix testing when running as root. (by Uwe
Kleine-König)
* Increase usage of g_autofree/g_autoptr in the test suite.
.. rubric:: Code
* Remove unused code for signed manifests (outside of a bundle).
* Add G_GNUC_WARN_UNUSED_RESULT to many functions.
.. rubric:: Documentation
* Fix multiple smaller errors. (by Christoph Steiger, Christopher Obbard and
Michael Heimpold)
* Improve documentation related to u-boot scripting and environment storage.

Release 1.4 (released Jul 20, 2020)
-----------------------------------
.. note::
Slots with both a ``parent=`` and a ``bootname=`` entry are now rejected when
parsing the system configuration.
While the intention was to have either a bootname or a parent link, this was
not enforced in previous versions.
Move the bootname to the parent slot when updating to RAUC 1.4.
It is now recommended to explicitly select either per-slot or global
configuration file in the system config using ``statusfile=<path>/per-slot``.
If a central storage location is available, global status file should be
preferred.
.. rubric:: Enhancements
* Added support for custom boot selection scripts/binaries.
This allows handling special cases where none of the standard bootloaders
is available for switching the redundant slots. (by Christian Bräuner
Sørensen, :ref:`docs <sec-custom-bootloader-backend>` by Andreas Schmidt)
* Changed ext4 filesystem creation options to always use 256 byte inodes.
Without it, mkfs.ext4 will default to 128 byte inodes on filesystems smaller
than 512MiB.
This avoids the "ext4 filesystem being mounted at /foo supports timestamps
until 2038" message on newer kernels.
* Added new slot type ``boot-gpt-switch`` to support atomic updating of boot
partitions in the GPT.
This is useful if the firmware does not support atomic bootloader updates by
itself.
See :ref:`here <sec-gpt-partition>` for details.
.. rubric:: Bug fixes
* Improve parent and bootname consistency checks when loading the system
config. (by Dan Callaghan)
* Fix and improve installation log output for the --disable-service
configuration.
* Clean up incomplete bundles on creation errors consistently for extract/resign/convert
and doesn't remove pre-existing files anymore.
* Fix minor memory leaks.
.. rubric:: Testing
* Added tests for UBIFS and NAND slot types via nandsim in qemu.
* Added CI testing of the --disable-service configure option.
* Added test cases for some CLI subcommands.
.. rubric:: Code
* Clarified licensing of the D-Bus API file. (by Michael Heimpold)
.. rubric:: Documentation
* Manual pages have been updated with new options. (by Michael Heimpold)
* Improved documentation around central and per-slot status files.
* Improved images and various text sections.

Release 1.3 (released Apr 23, 2020)
-----------------------------------
.. rubric:: Enhancements
* Added a new D-Bus method (InstallBundle) which supports optional parameters
("ignore-compatible" for now).
* Added support for X.509 key usage attributes (code signing and others).
* Added a ``check-crl`` configuration option to require Certificate Revocation
List (CRL) checking during installation.
If the keyring already contains a CRL, but checking is not enabled, a warning
will be printed.
* Support updating of already mounted slots via a custom install hook when
enabled with "allow-mounted=true" in the system configuration.
This can be useful for updating bootloaders in a boot partition (for example
on the Raspberry Pi or BeagleBone). (by Martin Hundebøll and Rasmus Villemoes)
* Added the ``--mksquashfs-args`` option for bundle creation. This can be used to
configure the details of the squashfs compression. (by Louis des Landes)
* Added the ``--casync-args`` option for the ``rauc convert`` command. This can
be used to configure the details of the casync conversion. (by Christopher
Obbard)
* Added support for installing UBIFS images via casync (depends on the casync PR
https://github.com/systemd/casync/pull/227). (by Ulrich Ölmann)
* Enabled usage of ``--no-verify`` with ``rauc resign``.
This can be useful for resigning of bundles signed with expired certificates.
* Exposed the ``RAUC_BUNDLE_MOUNT_POINT`` environment variable to hook scripts.
This also deprecates the old name ``RAUC_UPDATE_SOURCE`` for this value in
handler scripts. (by Rasmus Villemoes)
* Reduced size of the installed ``rauc`` binary. This was done by using
``--gc-sections`` and adding a configure switch to disable the ``bundle``,
``resign`` and ``convert`` commands. (by Rasmus Villemoes)
* Added support for explicitly telling RAUC that all slots are inactive on the
kernel command line (``rauc.external``).
This is useful for using RAUC in a factory installer. (by Marco Felsch)
* Improved layout of the ``rauc status`` output.
.. rubric:: Bug fixes
* Fixed SD/eMMC detection when using /dev/disk/by-path/ symlinks. (by Marco Felsch)
* Fixed handling of HTTP Content-Encoding: gzip. (by Jan Kundrát)
* Fixed reporting of errors during bundle verification. This solves a
``rauc-ERROR **: Not enough substeps: check_bundle`` abort. (by Rouven
Czerwinski)
* Fixed handling of surrounding whitespace in the system variant by removing
it. A warning is printed in this case.
* Fixed the RAUC D-Bus interface introspection file name to be consistent with
the interface name. (by Michael Tretter)
.. rubric:: Testing
* Switched testing environment from user-mode-linux (UML) to QEMU. This allows
us to use our own kernel configuration and avoids the (unusual) dependency.
* Re-enabled support for coverity, as they have added support for GCC 8.
* Added some more tests in several areas.
.. rubric:: Code
* Removed support for OpenSSL versions < 1.1.1.
OpenSSL versions 1.0.2 and 1.1.0 are no longer supported by the OpenSSL
project: https://www.openssl.org/policies/releasestrat.html
* Improved support for large bundles on 32 bit systems, but some work remains
to be done.
* Disabled automatic ``-Werror`` and ``-O0`` when building from a git
repository.
This caused confusion in several cases.
* Updated uncrustify and enabled some additional formatting rules.
* Reduced redundant prefixes in error messages.
* Removed unused verification functions left over from the old network mode.
* Removed minor memory leaks.
.. rubric:: Documentation
* Clarified documentation about hooks and handlers (and the available
environment variables).
* Fixed minor typos and inconsistencies.

Release 1.2 (released Oct 27, 2019)
-----------------------------------
.. rubric:: Enhancements
* Added ``--signing-keyring`` argument to specify a distinct keyring for
post-signing verification. This allows for example to use ``rauc resign``
with certs not verifying against the original keyring.
* Output of 'rauc status' is now grouped by slot groups to make it easier to
identify the redundancy setup.
Previously, the present slots were printed in a random order which was
confusing, especially when having more than three or four slots.
* Use pkg-config to obtain valid D-Bus install directories and clean up D-Bus
directory handling.
This adds libdbus-1-dev as new build dependency. (by Michael Heimpold)
* Moved various checks that could be performed before actually starting the
installation out of the atomic update region.
This allows RAUC to fail earlier without leaving behind a disabled slot group
with incomplete contents.
* Added optional ``--progress`` argument to ``rauc install`` that enables a
basic text progress bar instead of the default line-by-line log.
* Added ``tmppath`` to casync system config options to allow setting TMPDIR for
casync. (by Gaël PORTAY)
* Slot skipping was deactivated by default as it turned out to be unexpected
behaviour for many users.
The corresponding setting was renamed to 'install-same='
('force-install-same' will remain valid, too).
The means skipping writing for slots whose current and intended slot hashes
are equal must now be enabled explicitly.
This optimization is mainly useful for use-cases with a read-only rootfs.
* Added new slot type ``boot-mbr-switch`` to support atomic updating of boot
partitions in the MBR. (by Thomas Hämmerle)
See :ref:`here <sec-mbr-partition>` for details.
.. rubric:: Bug fixes
* Fixed detection of whether the bundle path is located in input directory for a
corner case.
* Fixed off-by-one error in printing the remaining attempts counter in the
uboot.sh contrib script (by Ellie Reeves)
* Fixed detection of mount points disappearing during the service's runtime.
* Added missing entry of 'service' subcommand to RAUC help text (if compiled
with service support).
* Fixed inappropriate resetting of BOOT_ACK flag in eMMC extCSD register
handling which could have prevented proper booting on some SoCs. (by Stephan
Michaelsen)
* Fixed leaking GDataInputStreams in boot selection and install handling that
led to steadily increasing number of open file descriptors in some scenarios
until exceeding system limits and leading to 'Too many open files' errors.
This was only problematic when installing many times without rebooting.
* Fixed 'uninitialized local' bugs in update_handler and config_file module.
(by Gaël PORTAY)
* PKCS#11 handling now does not silently accept missing (empty) PINs anymore,
but allows interactive prompt for entering it.
* Fixed bundle detection on big endian systems.
* Fixed size mismatches in printf formatter and struct packing on ARM32.
.. rubric:: Testing
* Fix checks that depended on implicit assumptions regarding the GHashTable
behaviour that are not valid anymore for newer glib versions.
* Added notes on required tools for unit testing and added check for
grub-editenv being present.
* Travis now also runs cross-compilation tests for platforms armhf, i386,
arm64, armel to allow early detection of cross-compilation issues with
endianness, 32 vs. 64 bit, etc.
.. rubric:: Code
* Reworked subprocess call logging for debugging and added remaining missing
log output to users of r_subprocess_new().
* Refactored slot handling code in new 'slot.c' module to be used for both
install and status information handling.
* Added qdbusxml2cpp annotations to rauc-installer.xml for interface class
generation. (by Tobias Junghans)
* Removed the deprecated 'network mode'.
Note that this does not affect RAUC's bundle network capabilities (casync,
etc.).
* Fixed clang compilation warnings (unused variable, printf formatter,
non-obvious invert statements).
* Various code cleanups, structural simplifications
.. rubric:: Documentation
* Added hints for creating ``/dev/data`` symlink to mount the right data
partition in dual data partition setups. (by Fabian Knapp)
* Extended manpage to cover 'rauc status' subcommands. (by Michael Heimpold)
* Fixed various typos.

Release 1.1 (released Jun 5, 2019)
----------------------------------
.. rubric:: Enhancements
* Check that we do not generate a bundle inside a source directory
* Added full GRUB2 support, including status and primary slot readback (by
Vitaly Ogoltsov and Beralt Meppelink)
* Allow passing a slot's name via commandline instead of it's bootname
* Show each slot's name in ``Booted from`` line of ``rauc status`` to simplify
identification
* Add ``resize`` option for ext4 slots to let RAUC run resize2fs on an ext4
slot after copying the image.
* Allow dumping the signer certificate (``--dump-cert``) without verification
* Allow specifying a keyring directory with multiple files to support
non-conflicting installations of certificates from different packages (by
Evan Edstrom)
* Add a bootloader option ``efi-use-bootnext`` (only valid when bootloader is
'efi') to disable usage of BootNext for marking slots primary.
* Support setting a system variant in the ``system-info`` handler via
``RAUC_SYSTEM_VARIANT``
* D-Bus "mountpoint" property now also exports external mount point
* Made slot state, compatible and variant available as environment variables
for slot hooks
* Made system variant variable available as an environment variable for bundle
hooks
