In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start..”

  • Intel Integer Scaling support
  • Intel async page flipping support
  • Initial support for AMD Green Sardine and Van Gogh APUs
  • Intel WiFi 6GHz band support
