Release notes from libcamera

libcamera v0.6.0

2025-11-27T11:55:39Z

The abi-compliance checker reports there are both ABI and API changes in this
release:

Binary compatibility: 99.3%
Source compatibility: 98.6%
Total binary compatibility problems: 4, warnings: 1
Total source compatibility problems: 18, warnings: 5

These have been planned to batch together a lot of recent development to
improve the public facing API, which has extended the previous merge window on
this occasion.

A full and detailed ABI report for those interested can always be generated
between any two versions with the internal tooling:

"./utils/abi-compat.sh v0.5.2 v0.6.0"

Integration Overview:

With 211 commits and a longer merge window, this is quite a substantial
release.

Key highlights include a new global configuration file system which will
replace or extend the current use of environment variables to configure runtime
behaviours.

The core V4L2 classes can now support the V4L2 Request API - which in turn has
brought in huge developments for the i.MX8MP Dewarper support allowing full
resize, scale, rotate and crop capabilities on top of also performing lens
dewarping.

The SoftISP continues to develop, and specifically the IPU7 has been added as a
supported configuration to the pipeline.

New tuning files have been added for Raspberry Pi platforms, improving support
for the Sony IMX335, IMX415, IMX462, and ST VD55G1 image sensors, and Decompand
support has been added for the Raspberry Pi 5.

At the core, we now require Meson 1.0.1, and various improvements have been
made for thrad handling, improving synchronisation and event dispatch, as well
as fixing the serialisation operations for isolated IPA modules.

In the applications components, there are fixes to cam adding more output
formats and qcam now behaves more consistently when no camera is selected. The
python bindings have received fixes for paths from meson, and the
FrameBuffer::planes wrapper.

On the Documentation side, there's a new theme refresh and clearer separation
between the internal and public API, and fixes to the contributing guidelines.

libcamera v0.5.2

2025-08-07T13:48:55Z

The abi-compliance checker reports 100% compatibility in this release.
As such the SONAME is maintained at 0.5.

Binary compatibility: 100%
Source compatibility: 100%
Total binary compatibility problems: 0, warnings: 0
Total source compatibility problems: 0, warnings: 0

This release brings 129 commits with some substantial development on gstreamer
for this release which is nice to see.

In core we can see development that cleans up ProcessManager in a drive to
reduce singleton patterns throughout libcamera. There's a new ClockRecovery
class from Raspberry Pi which supports the new Wallclock timestamps
metadata and provides the capablity for synchronising cameras across
devices which will very exciting to see in the future.

Pipelines are now able to limit the number of requests queued into the pipeline
handler which helps prevent issues when applications desire to use a larger
request queue. This is particularly beneficial to pipewire based applications
it seems with longer processing queues.

It's now possible to check if controls exist with new macros defined for
every control to help codebases compile against multiple versions:

LIBCAMERA_HAS_$VENDOR_VENDOR_$MODE_$NAME

And for developers we now have a b4-config file to support easily using the
tool to send patche to the mailinglist!

On the apps side, there's lots of development on Gstreamer, including fixing
bayer formats for 10/12/14/16 bit depths. Both cam and gstreamer now report the
camera properties in full with text representations of all the enum/properties.

With the IPA components, Raspberry Pi includes development and updates to
Autofocus and makes the maximum digital gain limits configurable. RKISP1 now
has ExposureValue control implemented using exposure compensation in the
agc_mean_luminance implementation. The ST vd56g3 camera sensor support is added
for both RPi and libipa platforms.

For Pipeline Handlers notable updates include the imx8-isi being fixed for
newer generation chips from NXP adding multi-camera support, and Wallclock
timestamp support added to Rapsberry Pi.

Finally, on the documentation side - a notable change is the update to use
spinhx-doxylink. This should prevent stale links being used in the
documentation pages but adds an extra tool to the dependencies for building the
documentation.

libcamera v0.5.1

2025-06-01T22:58:03Z

The abi-compliance checker reports 100% compatibility in this release.
As such the SONAME is maintained at 0.5.

Binary compatibility: 100%
Source compatibility: 100%
Total binary compatibility problems: 0, warnings: 0
Total source compatibility problems: 0, warnings: 0

This release brings 93 commits with a large proportion of fixes and
cleanup againt earlier releases. Improvements have been made to the
Raspberry Pi Camera Tuning Tools, and the geometry, matrix and vector
class helpers have been expanded for greater reuse throughout the
project.

Notably for packagers - IPA modules now have their own subdirectory
which should prevent undesirable surrupticious error messages that would
occur if packagers choose to install the V4L2 adaptation layer in the
same folder as the IPA modules.

The RKISP1 can now adapt to more complex input pipelines, including
FPGAs and multiplexors, which has been beneficial for users on the
i.MX8MP, and the IPA algorithms for i.MX8MP and RKISP1 continue to get
improvements.

The software ISP has a new Saturation control (available when the CCM is
enabled).

The Documentation and pipeline handler writers guide has been
re-reviewed and cleaned up.

On the application and test side, lc-compliance now includes
multi-stream tests, and cam has extended support for display formats and
now prevents issues on non-display GPUs when rendering direct to DRM.

libcamera v0.5.0

2025-04-03T13:38:41Z

The abi-compliance-checker reports there are both ABI and API changes in this
release:

Binary compatibility: 99%
Source compatibility: 99.5%
Total binary compatibility problems: 5, warnings: 1
Total source compatibility problems: 6, warnings: 1

Substantially less than the previous release, and ultimately quite minor but
unfortunately there nonetheless and so the SONAME is updated to 0.5
accordingly. I do not anticipate anything there that cannot be solved for
applications without just a recompile. I had hoped to get a longer run for 0.4
series...

A full and detailed ABI report for those interested can always be generated
between any two versions with the internal tooling:

"./utils/abi-compat.sh v0.4.0 v0.5.0"

Integration overview:

This release brings in 201 commits with a huge list of fixes and code clean up
which I'm very happy to see, including interesting fixes to the AGC and AWB
handling in libipa.

In regards to new features, libcamera-0.5 has aptly now got the core Raspberry
Pi 5 support merged!. There are still patches that are currently maintained by
Raspberry Pi for additional features, and while the transition to upstream
API's continue, but I think we're all happy to see this support getting in
directly, and Raspberry Pi continue to lead the way in upstream camera
development. I look forward to the kernel API's for streams being fully
utilised by the PiSP platform for upstream camera metadata handling. This
upcoming work is also supported by the CameraSensor factory and CameraSensorRaw
support that is now also merged in this release.

Further more in the platform support, the software_isp continues to be
developed and is now able to measure colour temperature, which will bring in
improvements for AWB, and a CCM can be applied while peforming debayering (at a
CPU cost) which will allow us to finally apply color tuning for sensors on
devices that need to fall back to the software ISP.

New sensor support seems fairly short in this release, with the IMX415 being
the prominent addition.

In libipa, and algorithm developments, along with many fixes and improvements
there is a substantial new feature that the Baysian AWB algorithm from
Raspberry Pi can now also be used on all libipa supported IPA modules, and has
shown good impovements for the RkISP1 supported devices.

There is minimal changes to the application support side, but it is notable
that now the Y444 format has been mapped to be usable by the gstreamer src
element. lc-compliance has seen some progress which I hope will bring this to
being a more central part of the test infrastructure.

The following commits in this release relate to either a bug fix or an

This is not too surprising as this was the reason for the extra delay holding
up this release, and as such this release bumps the SONAME to 0.4 accordingly.

The majority of the ABI breakages are around the public API for Control
handling and definitions, which have caused underlying identifiers to be
changed, and the reuqired storage for controls has increased.

I hope that grouping the expected ABI and API breakages and delaying this
release will allow a longer stability on the 0.4 series but as we are
developing rapidly this can not be guaranteed, though we aim to minimise
disruption to distributions and applications whereever possible.

This release brings in 253 commits, with substantial development on image
control and tuning features for IPA and Pipeline handlers supporting libipa, as
well as integrating libipa support for IPA handling on the ARM Mali-C55 ISP.

A new 'Virtual Pipeline Handler' has been introduced to support more testing in
CI and virtual environments.

Gstreamer has had some interesting development to rework expressing the full
control set from libcamera using auto generation from the full control
descriptors.

A key and notable change in this release too is that the softISP is now moving
towards utilising the libipa implementaitons which will enable future tuning
and image control capabilities, and should also support future development on a
GPU-ISP implementation for GPU-accelerated handling. I do believe this work may
have introduced an oscillation regression in the AEGC which will need to be
investigated and fixed in the near future, but I don't want to hold up
progressing the ABI updates at this stage.

The i.MX8MP can now make full use of the DW100 Dewarp Engine for full rotation
and digital zoom capabilities.

Raspberry Pi systems now have improved support for the OV7251, IMX462, and
IMX327 Sensors, and libipa platforms can now make use of the GalaxyCore gc05a2
and gc08a3 Image sensors.

libcamera v0.1.0

2023-07-16T11:46:40Z

ABI Compliance:

abi-compliance-checker reports 99% binary compatibility and 81.4% source
compatibilty between version 0.0.5 and 0.1.

Binary compatibility: 99%
Source compatibility: 81.4%
Total binary compatibility problems: 4, warnings: 2
Total source compatibility problems: 165, warnings: 7

Now that we have funtional ABI validation, the soname has been updated from
libcamera.so.0.0.5 to libcamera.so.0.1.

Future releases will now maintain the same soname until an ABI breakage is
detected to reduce the repackaging and rebuilding of other components that may
use libcamera. The abi-compatibility report can now be generated with the new
utility './utils/abi-compat.sh'.

Key differences here are due to preventing the installation of internal and
private headers in the packaging process, and most of this API compatibility
should not be visible to applications with the exception of:

Camera::generateConfiguration ( StreamRoles const& roles )

The StreamRoles type definition has been removed. This is now handled as a
Span to prevent unnecessary allocations and copies.
CameraManager::addCamera ( std::shared_ptr camera, std::vectorconst& devnums )
CameraManager::get ( dev_t devnum )
CameraManager::removeCamera ( std::shared_ptr camera )

These functions of the CameraManager were for use exclusively by the V4L2
adaptation layer, and not intended for use by applications. This has now been
reworked to use the new SystemDevices and the redundant functions removed.

The ABI/API breakages have been introduced by:

5ca0c92 ("libcamera: CameraManager: Remove ::get(dev_t)")
26a4b83 ("libcamera: Remove StreamRoles alias")
63966ae ("libcamera: base: Do not install private headers")
