 ### Bug Fixes

 * Fix clients being left on the wrong database after module keyspace notifications from commands like `MOVE` and `COPY` by @enjoy-binbin (#4024)
 * Fix an I/O thread job queue memory-ordering race that could trigger an assertion crash on ARM/aarch64 by @jjuleslasarte (#3878)
 * Reject zipmap `RESTORE` payloads with overflowing length fields that could cause out-of-bounds access on 32-bit builds by @madolson (#3920)
 * Reject NAN scores when loading listpack/ziplist-encoded sorted sets, preventing a crash from crafted `RESTORE` payloads by @madolson (#3921)
 * Fix a startup crash when generating `INFO` output on 32-bit systems where `time_t` is 64-bit (e.g.
 Alpine time64) by @chenshi5012 (#3787)
 * Fix `COMMAND INFO` in RESP3 to reply with an empty Array instead of a Set for commands without subcommands by @rickrams (#3939)
 * Reject invalid characters in cluster AUX fields and `cluster-announce-ip` to prevent `nodes.conf` corruption and injection by @eifrah-aws (#3848)
 * Fix `lua-enable-insecure-api` having no effect when enabled at startup via config file or command line by @enjoy-binbin (#3548)
 * Increase the maximum process title length from 255 to 1024 characters to avoid truncation with long installation paths by @pkhartsk (#3843)
