Recordings

We record/transcribe the main section of the meeting for publishing, but only the speaker is visible in the recording - and you can disable your video if you wish.
We shut this off after the agenda is exhausted and there’s time for more casual discussion after.

Notes

• Review of action items from last time
• Saviq: Working on cleaning up the slate to the latest distro releases, including Ubuntu, Fedora, Alpine, and more. This means that we’ll be working with C++26. We’ll be deprecating a bunch of APIs, meaning that a bunch of ABIs will also be deprecated. This is a great opportunity to have a clean slate. miral breakages include:
  • Removing our own mir::optional in favor of std::optional
  • Removing classes that were marked as “deprecated”
  • Add a new logging API that will break mircore
• Saviq: We are working on having more frequent releases. We are aiming for the next one in mid-August so that we have time to remove all of the things at once and take some nice vacations.
• Matt: mir-rs is in the works and is beginning to be implemented
• Saviq: ext-toplevel-image-copy-capture is now in main, which makes it so that the latest xdg-desktop-portal-wlr feature will work by default.
• Matt: miracle-wm has a new release. Working on geometry shader support.
• Alan: miriway will had a new release and will have another new release soon

Action Items

• Saviq: publish the Mir roadmap in the docs

• Alan: improve how-to-contribute stories

• Matt: explore implementation of experimental APIs in miral to accommodate the fancier things that Miracle is doing
