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 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.
