This release adds the Voltage LSP as an optional LSP if you pass through the URL: "https://testnet-lsp.voltageapi.com" in the nodemanager config options.
This also adds RapidGossipSync so that lightning gossip data can be retrieved quickly from a server, also a config option but has defaults based on network version.
LDK has been updated to v0.0.114 and now uses no-std.
Few bug fixes as well.
