It looks like new Trackmix firmware was released yesterday (v3.0.0.1817_23022700), but the release notes are the same as the previous release (v3.0.0.1584_221201). Can you let us know what the correct release notes should be?
Including the release notes of the new Trackmix firmware that you mentioned. My knowledge cutoff is September 2021, so I cannot provide any information about events or updates that occurred after that date. However, you can try visiting the website or the official support page of the manufacturer or developer of the Trackmix firmware to get the latest and most accurate information about the firmware release notes. They are the best sources to provide you with the correct release notes for the new version of the Trackmix firmware.

thanks for your help !!
