+#### Build 2309050
+-   Effect blending (#3311) (finally efect transitions!)
+    *WARNING*: May not work well with ESP8266, with plenty of segments or usermods (low RAM condition)!!!
+-   Added receive and send sync groups to JSON API (#3317) (you can change sync groups using preset)
+-   Internal temperature usermod (#3246)
+-   MQTT server and topic length overrides (#3354) (new build flags)

+-   various fixes and improvements (ESP variants platform 5.3.0, effect optimizations, /json/cfg pin allocation)
+
+#### Build 2307130
+-   larger `oappend()` stack buffer (3.5k) for ESP32
+-   Preset cycle bugfix (#3262)
+-   Rotary encoder ALT fix for large LED count (#3276)
+-   effect updates (2D Plasmaball), `blur()` speedup

+
+#### Build 2306210
+-   0.14.0-b3 release
+-   respect global I2C in all usermods (no local initilaisation of I2C bus)
+-   Multi relay usermod compile-time enabled option (-D MULTI_RELAY_ENABLED=true|false)
+
+#### Build 2306180
+-   Added client-side option for applying effect defaults from metadata
+-   Improved ESP8266 stability by reducing WebSocket response resends
+-   Updated ESP8266 core to 3.1.2

+
+#### Build 2306130
+-   Bumped version to 0.14-b3 (beta 3)
+-   added pin dropdowns in LED preferences (not for LED pins) and usermods
+-   introduced (unused ATM) NeoGammaWLEDMethod class
+-   Reverse proxy support
+-   PCF8754 support for Rotary encoder (requires wiring INT pin to ESP GPIO)
+-   Rely on global I2C pins for usermods (breaking change)
+-   various fixes and enhancements
+
+#### Build 2306020
 -   Support for segment sets (PR #3171)

+# Internal Temperature Usermod
+This usermod adds the temperature readout to the Info tab and also publishes that over the topic `mcutemp` topic.
+
+## Important
+A shown temp of 53,33°C might indicate that the internal temp is not supported.
+
+ESP8266 does not have a internal temp sensor
+
+ESP32S2 seems to crash on reading the sensor -> disabled
+
+## Installation
+Add a build flag `-D USERMOD_INTERNAL_TEMPERATURE` to your `platformio.ini` (or `platformio_override.ini`).
