“So last week was pretty quiet, there was a slow network update with fixes for loading some (mainly iwl wireless) network drivers and netfilter modules, but David did not guarantee another -rc. Apart from that, it was really very quiet, with updates to the Panfrost driver, but delaying the final release by another week didn’t make much sense.

… “
