CVE-2021-29478: Integer overflow in COPY command for large intsets (bsc#1185730)
Cluster: Skip unnecessary check which may prevent failure detection
Fix performance regression in BRPOP on Redis 6.0
Fix edge-case when a module client is unblocked
redis 6.0.12 :
Fix compilation error on non-glibc systems if jemalloc is not used
redis 6.0.11 :
CVE-2021-21309: Avoid 32-bit overflows when proto-max-bulk-len is set high (bsc#1182657)
Fix handling of threaded IO and CLIENT PAUSE (failover), could lead to data loss or a crash
Fix the selection of a random element from large hash tables
Fix broken protocol in client tracking tracking-redir-broken message
XINFO able to access expired keys on a replica
Fix broken protocol in redis-benchmark when used with -a or
–dbnum
Avoid assertions (on older kernels) when testing arm64 CoW bug
CONFIG REWRITE should honor umask settings
Fix firstkey,lastkey,step in COMMAND command for some commands
RM_ZsetRem: Delete key if empty, the bug could leave empty zset keys
Switch systemd type of the sentinel service from notify to simple.
