To address performance problems, this release improves observability by adding OpenTelemetry tracing, more Prometheus metrics and introduces the sidecar which is run as child process of the Node.js application.
Other notable changes are:
- Webhooks for swap status updates
- custom description hashes for invoices of Reverse Swaps (used for LNURL LUD-06 compatibility)
- custom Bitcoin Core and Elements wallet names
- labels for transactions on EVM chains
