  • support newer GdkPixbuf versions
• MS Windows:
  • client errors on control-c
  • packaging fix for python-pillow
  • warnings when named-pipes are the only local sockets available
  • directsound device queries
• Major:
  • virtual monitor geometry synchronization + fixup + another

  • handle notify2 backend failures gracefully
  • initial "fast" socket read could spin until the connection failed + fixup
  • DND errors under Wayland
  • X11 calls missing trap context
  • missing CUDA context when clients connect early
  • CUDA context leak
  • missing encodings
  • override-redirect windows using outdated dimensions
  • sub-image use after free
  • video downscaling becomes sticky
  • audio source could buffer to much
  • saved ssh key fingerprint never matched
  • explicit ssl handshake
  • generating image menu items is excruciatingly slow
  • header bar transparency issues
  • handle failure to add screen size more gracefully
• Printing:
  • incorrect cups backend exit codes could cause DoS, ie: FILE_TOO_BIG
  • use more widely compatible socket syntax
  • SELinux warnings + fixup
• Keyboard:
  • don't send empty modifier strings
  • default keyboard configuration should have default modifier mappings
  • help clients figure out modifier mappings
  • client keyboard 'options' attribute was not forwarded

  • keyboard repeat rate lost after client sets new keymap + fixup
• Minor:
  • try harder to locate the notification icons but not SVGs
  • honour the XPRA_MONITOR_CHANGE_REINIT environment variable
  • spurious UI thread events on client startup
  • expose desktop flag for desktop windows

  • XPRA_MIN_DPI would actually clamp the DPI to that value
  • bail out early when connection is already closed
  • clipboard tray menu entry is not pre-selected
  • netdev_query module is optional
  • bump version of the notification spec we claim to support
  • slots interfere with pygobject and should not be used

  • NVENC's hevc does support lossless mode
  • about dialog cannot be shown again
  • honour move-resize in read-only mode
  • revert: do honour USPosition / PPosition and USSize / PSize
  • always interact with Gtk from the main thread
  • file transfer data not freed on error
  • exclude nvjpeg from video fallback
  • cairo missing hint
  • better forwards compatibility
  • splash toggle not honoured with server start and attach
• Cosmetic:
  • make socket eof detection less spammy
  • invalid syntax used in man page
  • more useful message
  • log exception if that's all we have
  • XPRA_MIN_COMPRESS_SIZE environment variable did not match its intent
  • avoid warning when the server doesn't support av-sync
  • substitutions missing from log messages
  • EDID data scrambled the message
  • remove duplicate version data
  • avoid KeyError parsing some broken icon files
  • more meaningful labels on session info dialog
  • log line wrapping
  • correct type for XI2 cython bindings
  • file descriptor leak warning
  • paramiko ssh errors on close
  • unnecessary timer
  • potential race condition
  • only free valid timers
