# Changelog

## `0.3.1`

Added **ML-DSA44 post-quantum signing** as a new API authentication option alongside HMAC SHA256.

You can now secure requests using either:

* HMAC
* ML-DSA44 ([post-quantum safe](https://openquantumsafe.org/liboqs/algorithms/sig/ml-dsa.html))

This brings NIST-standard quantum-resistant signatures to the developer API.

## `0.3.0`

LLM Sessions no longer rely on parsing plain-text responses such as `LONG`, `SHORT`, or `EXIT`. Signal generation has been upgraded to native tool calling, allowing AI strategies to open and close positions directly through built-in trading tools.

Introduced the new `set_storage` [tool](/startegies/llm-session/signal-generation.md#llm-tooling-reference). LLM strategies can now maintain their own persistent JSON storage, which is automatically provided on every execution. This enables AI strategies to track state, remember previous decisions, manage workflows, and build more advanced long-term reasoning processes.
