Absolutely thrilled to finally put it out: Cashu Nutshell 0.15.0 is released with many changes. Most importantly, this update implements the new Cashu v1 protocol (while remaining backwards compatible with old wallets and mints). This update also paves the way for Ecash in multiple denominations (sats, msats, usd, ...) and for supporting multiple payment methods (Lightning, on-chain, ...).

Wit this release, we're also about to get serious: We're preparing for distributing the mint in a cluster to run it in a high-availability and hardcore-throughput setting and allow for thousands of transactions per second.
