 ## Version history
+#### v0.7.534
+- added control via uart (see [list of commands](https://github.com/e2002/yoradio/wiki/List-of-available-commands-(UART-telnet-GET-POST))). The uart and telnet commands are the same.
+- added additional commands
+- added control via GET/POST (see [list of commands](https://github.com/e2002/yoradio/wiki/List-of-available-commands-(UART-telnet-GET-POST)))
+- fixed clock operation when configured with DSP_DUMMY
+- fixed RSSI display in web interface when configured with DSP_DUMMY
+- added brightness control/on/off nextion displays from the web interface
+- new parameter WAKE_PIN (to wake up esp after sleep command earlier than given time (see exsamples/myoptions.h and list of commands)
+- minor memory optimization
+
 #### v0.7.490
 **!!! a [full update](#update-over-web-interface) with Sketch data upload is required. After updating please press CTRL+F5 in browser !!!** \
 **Please backup playlist.csv and wifi.csv before updating.**
