This has been pending for way too long.

>From the ChangeLog:

8.4.11-1 (api:genl1/proto:86-101)
 * New efficient ZEROES command on the wire,
   to clearly distinguish zero-out from trim/discard/unmap.
 * compatibility with Linux kernels up to 4.17 (and RHEL up to 7.5)
 * runtime sanity check for silent RHEL 7.5 kABI breakage 
 * Fix bug in compat code: Without this fix large bios are not split.
   The user visible behavior is then a hanging DRBD.

[ NOTE: ^^ that was a regression in 8.4.11 rc1, so 8.4.10 was NOT affected ]

 * skip spurious timeout (ping-timeo) when failing promote
 * don't retry connection if peers do not agree on "authentication" settings
 * avoid spurious self-outdating with concurrent disconnect / down
 * do not block when adjusting "disk-options" while IO is frozen
 * fix various corner cases when recovering from multiple failure cases
