+* For developers: added function for getting standardized UART pin descriptions.
+
+Drivers:
+
+* ESP32, iMXRT1062, RP2040: added optional data to `$PORTS` command.
+
+* STM32F1xx: fixed board map causing compilation errors.
+
+* STM32F4xx: changed code that older compiler used by platformio flagged as invalid.
+
+Plugins:
+
+* WebUI: fix for bad refactor of optional authentication code.
