- [@nickray] released `salty` ([API][salty-api], [book][salty-book], [code][salty-code]), a library for fast Ed25519 signatures on Cortex-M4 and Cortex-M33 microcontrollers. It presents the `ed25519-dalek` API, but is self-contained and uses the fastest currently published field operations implementation, due to Bjoern Haase, based on the `UMAAL` DSP instruction `(a: u32, b: u32, c: u32, d: u32) -> (a * b + c + d): u64`. Testing is done on the `musca-b1` Cortex-M33 microcontroller, simulated in QEMU v4. Additionally, a C API is included.
