Simon Ser: Status update, May 2023
Hi all!
This status update comes in a bit late because I was on leave last week. The highlight this month is the HDR hackfest, I’ve written a dedicated blog post about it. After the publication of that blog post, I’ve sent out an RFC to dri-devel.
We’ve made some good progress on wlroots’ Vulkan renderer. Manuel Stoeckl has added support for an intermediate buffer for blending, which is required for non-8-bit output formats and for color management features. The renderer now has an optional extra rendering pass to run a shader after blending. This is currently used to encode color values to sRGB, and will be used in the future to apply ICC profiles and to perform color space conversions. I’ve added support for the NV12 DMA-BUF format, support for more YCbCr formats is in a merge request.

Python 3.12.0 beta 1 released
Python 3.12 is still in development. This release, 3.12.0b1, is the first of four planned beta release previews of 3.12.
Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release.
We strongly encourage maintainers of third-party Python projects to test with 3.12 during the beta phase and report issues found to [the Python bug tracker (Issues · python/cpython · GitHub) as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Monday, 2023-07-31). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.12.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.12 as possible during the beta phase.
