In September, progress has been made on adding MuSig2 support to coinlib.

A fork of secp256k1 has been created which includes MuSig adaptor support which is required for DLCs: [GitHub - peercoin/secp256k1-coinlib: Fork of secp256k1 with additional features for coinlib including adaptor signatures](https://github.com/peercoin/secp256k1-coinlib)

Key aggregation, and partial signing has been implemented. The next step is to add partial signature verification and aggregation.
