Hello All,
I'm pleased to share that libcamera v0.7.0 "Brussels" has been released,
tagged and pushed.
Archives are available from:
- https://gitlab.freedesktop.org/camera/libcamera/-/releases/v0.7.0
This release brings 158 commits with substantial development on the SoftISP
components. This brings in GPU acceleration, allowing us to get higher
throughput for cameras using this pipeline. Further development to improve the
image quality is ongoing now that we can perform more processing in realtime.
The simple pipeline handler now supports exposing the Raw streams directly
allowing us to enable the SoftISP by default without removing access to the
camera formats.
Kernel headers have been updated to v6.18, supporting the new V4L2 ISP kernel
interface which allows us to continue improvements to hardware ISP pipelines as
we add new features.
Logging has been improved to better detect when to enable or disable color
output and can be controlled through the environment variable
LIBCAMERA_LOG_COLOR.
A new control is added for LensShadingCorrectionEnable to allow runtime control
over the LSC components where supported.
The gstreamer pipeline now has raw support added to the libcamerasrc
stream-role property allowing raw streams to be configured and accessed.
An exciting new AWB algorithm using Neural Networks, has been added to the
Raspberry Pi IPA following extensive development and training performed by the
Raspberry Pi Camera Team.
And finally, the Documentation now includes a support matrix which will help
identify the current support and enablement for platforms and sensors.

Integration overview:
ABI:
The abi-compliance checker reports 100% compatibility in this release. But it's
a complete lie... so we're moving to v0.7.0 and increasing the SONAME for this
release.
$ ./utils/abi-compat.sh
Validating ABI compatibility between v0.6.0 and v0.7.0

Binary compatibility: 100%
Source compatibility: 100%
Total binary compatibility problems: 0, warnings: 3
Total source compatibility problems: 0, warnings: 0
Report: compat_reports/libcamera/v0.6.0_to_v0.7.0/compat_report.html
The warnings reported are diagnosed as low severity but relate to a change of
the structure size of the public API Request object, which will require a
recompile of any users.
