Hi all,
I'm pleased to share that the libcamera v0.3.1 'Alpe Gsohl' release has
been tagged and pushed.
Archives are available from:
- https://gitlab.freedesktop.org/camera/libcamera/-/releases/v0.3.1
## ABI Compliance
There are no ABI breaking changes in this release so no update has been
made to the SONAME. Existing applications are expected to continue to
work against this release without updates.
Binary compatibility: 100%
Source compatibility: 100%
Total binary compatibility problems: 0, warnings: 0
Total source compatibility problems: 0, warnings: 0
## Integration overview
Noteably to packagers, QCam has now been updated to use QT6 and we have
dropped the requirement for QT5 which is end of life.
This release brings quite a substantial amount of ongoing development to
the image processing on RKISP1 and developments to the libtuning
components.
The IPU6 is now supported by the SoftISP and Simple Pipeline handler and
the Onsemi AR0144 is now supported by libipa. A new control has been
added to support setting and reading of Gamma, and gamma control has
been added to the RKISP1 IPA.
The following commits in this release relate to either a bug fix or
improvement to existing commit.
