 Changelog
 =========
-### 2.1
+### 3.0-dev1
 - Complete re-write of the web frontend. Requires a WebSockets capable browser.
+- Migrated to ESPAsyncUDP for E131 parsing (E131 library updated).
+- Increased WS2811 reset time from 50us to 300us to support newer WS2811 chips.
+- Added hostname configuration.
 - Added GBR and BGR color order for pixels.
-- Changed WS2811 reset time from 50us to 80us to better support WS2811 clones.
 
 ### 2.0
 - Added web based OTA update capability.
