• date: 2026-01-30 release: 2.95.0 cls: [2311] message: Introduced as warning.

The short-hand notation for floating point numbers .123 instead of 0.123 is deprecated. Floating point literals are seldomly used, and saving one character adds little benefit. This deprecation will free the syntax for possible future new language feature (See NixOS RFC 181).

To fix this, add a zero before the dot.
