Great progress on the electrum endpoint today. Updated all tests with version conditions, for initial availability, additions, behavior changes, and obsolescence. Implemented server.features and server.ping methods. Improved electrum test harness and expanded coverage.
Also verified bs<-bs and bs<-core full chain and multi-channel sync on windows and linux and on manual and inbound channels (most sync we test has been multiple outbound channels over the Internet). Performance looks excellent. Getting close to being able to provide clean benchmarks for blocks out, with the expectation that we should be able to provide the full chain out as fast as we can sync it in.
