Fixes a critical issue related to streams. From the release notes:
================================================================================
Redis 5.0.9 Released Thu Apr 17 12:41:00 CET 2020
================================================================================
Upgrade urgency:CRITICAL if you use Streams with AOF ore replicas.
Otherwise the upgrade urgency is LOW.
This release has a speed improvement and a critical fix:
* FIX: XREADGROUP when fetching data in a blocking way, would not
emit the XCLAIM in the AOF file and to replicas. This means
that the last ID is not updated, and that restarting the server
will have the effect of reprocessing some entries.
* NEW: Clients blocked on the same key are now unblocked on
O(1) time. Backported from Redis 6.
