 - [@nickray] released `littlefs2` ([API][littlefs2-api], [code][littlefs2-code]), an idiomatic Rust API for the [`littlefs`][littlefs-upstream] filesystem for microcontrollers, modeled after `std::fs`. The upstream library claims to be resilient against power-loss, and supports features like dynamic wear-leveling with bad block detection, inline files for efficient use of storage, and custom user attributes on files and directories.
 
+- [@nickray] released `nisty` ([API][nisty-api], [code][nisty-code]), a companion library to `salty` with similar API, but for NIST P-256 signatures on Cortex-M4 and Cortex-M33 microcontrollers. It offers deterministic signatures, idiomatic conversions, and uses [`micro-ecc`][micro-ecc] as backend implementation, which also has `UMAAL` DSP instruction optimizations.
