 # ESP32Radio-V2
-New version of the well known ESP32 Radio.  Now optional I2S output!
+New version of the well known ESP32 Radio.  Now optional I2S output and SP/DIF output!
 - Compile time configuration in config.h.
 - Do not forget to upload the data directory to the ESP32.
 - SD cards supported, but still experimental.

+
 Updates:
+- 23-jun-2025: data/search.html correction for not working external page.
+- 29-apr-2025: Some corrections for SD card.  Added configurable toggle for "mute".
+- 19-mar-2025: Correction for new Espressif SDK.
+- 17-oct-2024: Experimental support for ESP32-S3. SP/DIF tested.
+- 05-jul-2024: Correction SPDIF output.
+- 12-mar-2024: Add document with building instructions.  New PCB available! See [here at PCBWay](https://www.pcbway.com/project/shareproject/W652317AS2P1_Gerber_ESP32_Radio_PCB_ESP32_Radio_fab8a6d9.html).
+- 19-feb-2024: SP/DIF (Toslink) output, fixed mono bug.
+- 26-dec-2023: Correct crash with VS1053 and empty preferences.
+- 14-dec-2023: Add "mqttrefresh" command to refresh all mqtt items.
+- 09-oct-2023: Reduced error messages caused by uninitialized GPIO numbers.
+- 16-may-2023: Added sleep command.
+- 05-may-2023: SD card file stored on SD card, mute/unmute, better mutex.
 - 24-mar-2023: Code clean-up
 - 03-nov-2022: Added AI Thinker Audio kit V2.1 suport.
 - 05-oct-2021: Fixed internal DAC output, fixed OTA upload.

+ESP32Radio.zip Contains the project as an Arduino sketch.
+Edit config.h for your configuration....
+Enable core debug level "Info" in the tools menu.
+
+There is no simple way to upload the SPIFFS files in version 2 of the Arduino IDE, so use version 1.
