The llama.cpp library released version b11366 on Oct 3 2026. It fixes a bug where the quantization scale search could produce infinite or NaN values, causing an assertion failure in Debug builds. The fix clamps the quantization level to a safe range before rounding. Regression tests were added for several quant types. The change applies across all supported platforms, from macOS to Windows and Linux.

## The facts

- Release date: Oct 03 2026 – "Sat Oct 03 2026 03:55:51 GMT+0200"
- Fix prevents invalid rounding in qkx3 scale search (issue #29804)

## Why it matters

Developers using llama.cpp will see fewer crashes when debugging quantized models, improving stability during development.
