Bugfix and papercut release

  • Improved shadow server:
    • faster encoding by avoiding unchanged areas
    • back pressure from client: if it can not keep up with in flight frames reduce quality and do not send new frames
    • windows backend improvements
    • mac os backend improvements
  • hashless certificate support (Ed25519, Ed448, ML-DSA, SLH-DSA)
  • apple videotoolbox h264 encoder/decoder support
  • various RAILS fixes (x11 and sdl)
