It's September 14th, 2026, and here's what moved in Redis today.
The clearest theme is performance work on the hot paths that touch every write. Two pull requests from ww8191201-coder, numbers 15785 and 15786, bring hardware-accelerated CRC64 to RISC-V systems. The first adds a carry-less-multiply implementation using the Z-B-C extension for the checksum work behind RDB and AOF…
In the same performance vein, PR 15787 from mpozniak95 fixes a subtle inefficiency in floating-point formatting. A lookup table inside the Grisu digit generator was declared mutable when it's actually constant, which forced the compiler to emit a real division instruction every time Redis formats a double into a…
Second theme: routine dependency maintenance. Four separate pull requests from AvivDavid23, numbers 15788 through 15792, each bump the bundled RedisTimeSeries module to a newer patch release. They're independent, low-risk version pins with no logic changes, but five of them landing together is worth noting if you're…
On the reliability side, PR 15714, merged by vitahlin, fixes a flaky test around hash field expiration. The original test used a 500 millisecond TTL that slow CI storage could exhaust…
