Firmware v1.12.1-rc1

What device, do you mean? I don‘t know any 1.12.1 RC1

Yes but it is Beta Channel so wait till release

A changelog would be nice to be able to check with specific devices wether the new/fixed functionality is given. Without any comment I won't update any device, even if it's usage is not "critical" (I'm ok with using some shelly devices of my setup as beta-tester).
