v5.0.10

• Platforms, build and packaging:
  • syntax compatibility fix, and another one
  • openssl.cnf location in MS Windows builds
  • force rebuild of dummy driver RPMs
  • Fedora can build html documentation again
  • always build the latest dummy DEB
  • MS Windows multi-page printing
  • run CI builds with Python 3.6 and 3.12, this requires Ubuntu 20.04
  • remove outdated numpy workaround
  • libyuv 0.1878
  • nasm 2.16.03
  • cython 3.0.11
  • aioquic 1.2.0
  • pynvml 12.555.43
  • pycuda 2024.1.2
  • pycuda RPMs to link against the system boost library, but not on RHEL 8
  • build fix for ffmpeg v7 decoder and csc module
  • build CUDA kernels with clang++ instead of gcc >= 14
  • don't ship any Qt components in this branch
  • skip xauth setup on MS Windows servers
• Major:
  • system tray docking causing server crashes + fixup
  • MS Windows PDF printing crash, library mismatch
  • honour ssh option when re-connecting
  • missing http headers caused html5 client caching
  • mDNS browser handling for binary text records from zeroconf
  • sync-xvfb: always free images with an error context
  • better compatibility with all builds of python cryptography
  • uninitialized pixels when resizing windows
  • window border offset with non-opengl renderer
  • client errors out with window forwarding disabled, remove more assumptions
  • xshape client errors with desktop scaling
  • xshape windows should still honour the window border
  • expose all clipboard targets
  • clipboard INCR transfers get stuck
  • scroll paint corruption
  • connection drops when downscaling
  • authentication aborted due to encryption not detected
  • always set a default initial resolution
  • honour the initial resolution, even if resizing is disabled
  • failure to add new virtual monitors
  • http directory listing + handler errors
  • avoid Directory listing forbidden error
• Encodings:
  • mmap race condition
  • validate openh264 colorspace
  • test used potentially invalid colorspace
  • avoid slow modules and slow encoders
  • reduce how often quality swings cause scaling changes
  • stick to the same video scaling value longer
  • sub-optimal non-scroll areas
  • prettier sampling filter when downscaling
  • nvenc causing decoding errors
  • workaround nvenc padded frames: openh264 decoder and ffmpeg decoder
• Keyboard:
  • keyboard-sync switch not honoured and not sent
  • ignore MS Windows keyboard layouts without a valid X11 layout name
  • try harder to identify the key event string
  • don't show duplicate keyboard layout names
  • try harder to find a matching key by name try lowercase if needed, use default modifiers if that's all we've got
• Minor:
  • remove enum prefix with older Python versions
  • ssl path checks
  • RFB connections cannot be upgraded to http or ws
  • make it possible to skip NM api
  • expose QUIC sockets via mDNS
  • only enable gtk error context with x11 Gdk backend
  • handle empty ibus daemon command
  • handle invalid dbus-launch command
  • system tray setup failures with non-composited screens, ie: 8-bit displays
  • map missing modifiers using defaults
  • don't setup ssh agent dispatch when ssh is disabled
  • request mode failures
  • proxy servers should respond to id requests
  • system tray menu encoding options don't stick
• Cosmetic:
  • errors when connections are closed as we process them
  • try to prevent ATK warnings
  • validate application's opaque-region
  • slow CI test times out, ignore it
  • only import modules actually needed: notifications, windows, mmap
  • desktop-scaling=no parsing warnings
  • log ssl error just once per socket
  • OpenSSH documentation misplaced
  • we do have tests
  • incorrect exception debug message and format
  • paramiko looks unmaintained
  • AES modes and keydata safety documentation
  • missing line continuation backslash in example
  • missing quote
  • log opengl probe command
  • clarify display name message
  • support the same resolution aliases as newer versions
  • log randr error code
  • X11 client messages warnings
  • avoid 'none' values warnings with video options
