KasmVNC 1.5.0

Features​

  • Disabled STUN IP discovery by default.
  • Added a video streaming mode with hardware- and software-accelerated H.264, H.265, and AV1 encoders. Hardware acceleration uses VAAPI (Intel/AMD) and NVENC (NVIDIA).
  • Added a relative mouse input mode for improved UX and application compatibility, including games and applications that rely on raw mouse deltas.
  • Configuration settings can now be overridden via environment variables.
  • Added optional systemd auto-start integration for deb and rpm packages, including support for starting multiple KasmVNC instances per user and improved upgrade and uninstall handling. (All supported distros include systemd except Alpine.)
  • Added openSUSE Leap 16 support.
  • Added Fedora 42 and 43 support. Retired support for Fedora 40 and 41.
  • Added Alpine 3.22 and 3.23 support. Retired support for Alpine 3.18, 3.19, and 3.20.
  • FFmpeg 8 compatibility — removed use of the deprecated avcodec_close API.
