- #15513 Prevented a division-by-zero error when active defragmentation thresholds are configured with equal or reversed value
- #15453 Clients blocked on `BLPOP`, `BLMOVE`, or `BLMOVEM` could remain blocked after `SORT` with `STORE` replaced the target key with a list

- #15539 Loading an AOF file with an RDB preamble could fail when active defragmentation was enabled
- RediSearch/RediSearch#10528 Crash in the numeric range tree when background garbage collection encounters an empty leaf during active indexing on a numeric field. (MOD-16877)
- RediSearch/RediSearch#10605 FT.CREATE and FT.ALTER now reject an empty string as a field name, preventing a crash loop in the fork-GC on indexes with an empty TAG field. (MOD-17034)
- RediSearch/RediSearch#10488 FT.INFO reports a negative num_records after garbage collection on indexes that include an INDEXMISSING field. (MOD-16940)

- RediSearch/RediSearch#10605 FT.CREATE and FT.ALTER now return an error when a field name is an empty string; previously such schemas were accepted silently. (MOD-17034)
- RediSearch/RediSearch#10522 coord_total_query_warnings_timeout double-counts timeout warnings for FT.SEARCH queries that use a hybrid (vector + filter) execution path. (MOD-15973)
