Good morning. This is your Redis weekly recap for April 20th through 27th, 2026.
Six pull requests merged and five additional commits this week, with a clear focus on performance optimization and data integrity.
Starting with performance improvements: Filipe Oliveira merged a significant optimization to the fast_float_strtod implementation, widening the fast path to handle 17-19 digit mantissas. This addresses a regression identified through bisection testing where roughly 50% of random double scores in ZADD listpack…
Moving to critical fixes: Three memory safety issues were resolved this week. Darsheel Rathore fixed a use-after-free vulnerability in the cluster message receiver registration function, where removing the head node from a linked list left a dangling pointer. Vitah Lin addressed a signed integer overflow in the scan…
For data integrity, sggeorgiev contributed two important stream-related fixes. The first prevents RDB corruption by detecting when the same NACK entry is incorrectly referenced by multiple consumers, now failing fast with a clear diagnostic message rather than allowing silent data corruption. The second fix resolves…
Finally, Shun Lee reduced log noise in…
