Thank you. It looks like the latest firmware version is 309, and Debian 
sid/unstable still ships version 288 in *firmware-atheros* 20230625-2 [1].

Unfortunately, there does not seem to be a change-log for version 309 
(or any version for that matter). I am going to manually copy it anyway, 
but it’d be nice, if I knew what to expect. ;-)


Kind regards,

Paul
