BTCPay Server v1.9.0 Released

BTCPay Server is a free and open-source Bitcoin payment processor which allows you to accept bitcoin without fees or intermediaries.

"We've added some quality-of-life improvements aimed explicitly toward the retail experience of the software, better management features for your stores, and some touch-ups toward checkout V2. Most prominently, we’ve released a wallet integration with exchanges!"

Highlights

Exchange integration via plugins
Point of Sale devices, improved NFC experience and better digital receipts
Checkout v2 gets further improvements
New recovery seed phrase view
Wallet labels export - BIP-329 and better label management
Restructuring how metadata is viewed
Deprecating MySQL and SQLite
Bug fixes

Breaking change

As part of our effort to withdraw support for MySQL and SQLite, if you start BTCPay Server with --sqlitefile or --mysql without being in the context of a migration, your server will fail to start.

We introduce another flag, --deprecated, which allows you to start with SQLite or MySQL even if it is deprecated. We will remove this flag in version 1.10.
