Linux 5.11 should be released today as stable but we'll see if 5.11-rc8 is decided instead given there has been an uptick in last minute changes for this kernel. This will mean either the Linux 5.12 merge window is kicking off at the end of today or could be pushed back by one week, but in whatever case there are many changes that have been queuing up for this next kernel version window...
