KasmVNC provides remote web-based access to a Desktop or application.
While VNC is in the name, KasmVNC differs from other VNC variants such
as TigerVNC, RealVNC, and TurboVNC. KasmVNC has broken from the RFB
specification which defines VNC, in order to support modern technologies
and increase security. KasmVNC is accessed by users from any modern
browser and does not support legacy VNC viewer applications. KasmVNC
uses a modern YAML based configuration at the server and user level,
allowing for ease of management. KasmVNC is maintained by Kasm
Technologies Corp, www.kasmweb.com.

* Tue Nov 29 2022 KasmTech <info@kasmweb.com> - 1.0.0-1
- WebRTC UDP transit support with support of STUN servers
- Lossless compression using multi-threaded WASM QOI decoder client side
- New yaml based configuration
- Significantly improved FPS through both client-side and server-side improvements.
- Support for the admin to define arbitrary http response headers for the built in web server
- Support for additional mouse buttons
- Refinement of vncserver checks and user prompts
- Added send_full_frame to developer API, forces full frame to be sent to all connected users that have at least read permission.
* Tue Mar 22 2022 KasmTech <info@kasmweb.com> - 0.9.3~beta-1
* Fri Feb 12 2021 KasmTech <info@kasmweb.com> - 0.9.1~beta-1
- Initial release of the rpm package.
