 ### 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.
@@ -23,6 +29,7 @@
 - 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.
