These were all unresolved at the time the 5.7 window opened, and needed some additional time to ensure they were correctly addressed. They are ready now. At the moment I know of one more urgent issue regarding the NFS server. A fix has been tested and is under review. I expect to send one more "5.7-rc fixes" PR, containing this fix (which now consists of 3 patches).
