 This app uses WebRTC to stream a desktop inside of a docker container, original author made this because [rabb.it](https://en.wikipedia.org/wiki/Rabb.it) went under and his internet could not handle streaming and discord kept crashing when his friend attempted to. He just wanted to watch anime with his friends ლ(ಠ益ಠლ) so he started digging throughout the internet and found a few *kinda* clones, but none of them had the virtual browser, then he found [Turtus](https://github.com/Khauri/Turtus) and he was able to figure out the rest.

 ## Use-cases and comparison
 
 Neko started as a virtual browser that is streamed using WebRTC to multiple users.
 - It is **not only limited to a browser**; it can run anything that runs on linux (e.g. VLC). Browser only happens to be the most popular and widely used use-case.
-- In fact, it is not limited to a single program either; you can install a full desktop environment (e.g. XFCE).
+- In fact, it is not limited to a single program either; you can install a full desktop environment (e.g. XFCE, KDE).
 - Speaking of limits, it does not need to run in a container; you could install neko on your host, connect to your X server and control your whole VM.
 - Theoretically it is not limited to only X server, anything that can be controlled and scraped periodically for images could be used instead.
   - Like implementing RDP or VNC protocol, where neko would only act as WebRTC relay server. This is currently only future.

 ## master branch
 
+### New Features
+- Added nvidia support for firefox.
+
+## [n.eko v2.8.0](https://github.com/m1k1o/neko/releases/tag/v2.8.0)
+
+### New Features
+- Added AV1 tag, metadata and pipeline. Unfortunately does not work yet, since the encoding is way too slow (by @mbattista).
+- Added `m1k1o/neko:kde` tag as an alternative to `m1k1o/neko:xfce`.
+- New VirtualGL version 3.1 was released, adding support for Chromium browsers to use Nvidia GPU acceleration!
+- Added `?embed=1` parameter to the URL, which will hide the sidebar and the top bar, so that it can be embedded in other websites.
+- Added `?volume=<0-1>` parameter to the URL, which will set the inital volume of the player (by @urbanekpj).
+- Touch events are now supported on mobile devices (by @urbanekpj).
+- Added NVENC support, hardware h264 encoding for Nvidia GPUs!
+- Fixed an issue where `nvh264enc` did not send SPS and PPS NAL units (by @mbattista).
+
 ### Bugs
 - Fixed TCP mux occasional freeze by adding write buffer to it.
 - Fixed stereo problem in chromium-based browsers, where it was only as mono by adding `stereo=1` to opus SDP to clients answer.
 - Fixed keysym mapping for unknown keycodes, which was causing some key combinations to not work on some keyboards.
+- Fixed a bug where `max_fps=0` would lead to an invalid pipeline.
+- Fixed client side webrtc ICE gathering, so that neko can be used without exposed ports, only with STUN and TURN servers.
+- Fixed play state synchronization, when autoplay is disabled.
+
+### Misc
+- Updated to go 1.19 and Node 18, removed go-events as dependency (by @mbattista).
+- Added adaptive framerate which now streams in the framerate you selected from the dropdown.
+- Improved chinese and korean characters support.
+- Disabled autolock for kde, so that it does not lock the screen when you are not using it.
+- Refactored autoplay, so that it will start playing audio, if it's allowed by the browser (by @urbanekpj).
+- Renamed pulseaudio sink from `auto_null` to `audio_output`, because it was ignored by KDE.
+- Pulseaudio is now configured using environment variables, so that users can mount `/home/neko` without losing audio configuration.
