+## [1.5.0] 2019-02-
+
+### Added
+
+- Support for RC10 thermostat
+
+### Changed
+
+- removed MQTT and WIFI settings from my_config.h. These have to be set either within the application (using set) or hardcoded in platformio.ini
+- Improved Tx logic. Retries are more efficient and startup is faster
+- # Rx telegrams and # Tx telegrams show number of successful Reads and Writes initiated by the user or automatically
+
+### Removed
+
+- poll and tx commands
+- DEBUG_SUPPORT. Now controlled with the 'set serial' command
+- TxCapable removed

+The ESP8266 will start in Access Point (AP) mode. Connect via WiFi to the SSID **EMS-ESP** and telnet to **192.168.4.1**. Then use the set command to configure your own network settings. Alternatively connect the ESP8266 to your PC and open a Serial monitor to configure the settings. Make sure you disable Serial support before connecting the EMS lines using `set serial off`.
 
 `set erase` will clear all settings. `set` wil show all settings.
 
 ## Troubleshooting
 
-If the WiFi fails to connect you won't be able to debug using the Telnet so re-build the firmware using the `-DDEBUG_SUPPORT` by un-commenting `debug_mode` in `platformio.ini`. Then connect the ESP8266 to a USB in your computer and monitor the Serial output. A lot of detailed logging will be printed to help you pinpoint the cause of the error for the Wifi, MQTT, MDNS and other things.
+When flashing for the first time the Serial port is enabled by default. You can then use a PC with USB to the ESP8266 to set the settings like wifi, mqtt etc and also monitor the boot up procedure. Remember to disable the serial (`set serial off`) when connecting to the EMS lines.

 Some annoying issues that need fixing:
 
-- Very infrequently an EMS write command is not sent, probably due to a collision somewhere in the UART between an incoming Rx and a Poll. The retries in the code fix this for now.
+- On newer EMS+ Boilers the Tx commands for reading and writing may not always work. I believe there is some handshake that needs to happen before the UBA3/Master is able to send a poll request to our service device.
