2. With a purpose to simplify the Docker entrypoint, we’re now not producing a zebrad.toml file or translating legacy Docker atmosphere variables. Node operators counting on any of the above should change to the brand new config.rs equivalents.
3. We’ve got made block template technology a part of the default zebra construct and have cleaned up zebrad/Cargo.toml to take away the getblocktemplate-rpcs characteristic flag. Because of this, the next construct command is now not supported: cargo construct --features getblocktemplate-rpcs
