Frigate v1.2.0 has been released. Frigate is an experimental Electrum server testing efficient Silent Payments scanning with ephemeral keys. The major feature in this release is GPU acceleration of the cryptographic computation required for Silent Payments scanning. This provides a dramatic (over 10x) performance improvement over CPU computation, and makes a public Silent Payments Electrum server a practical reality for the first time.
