This has modified quite a lot of surroundings variables which is able to have to be up to date in any scripts or configuration information which are utilizing the outdated names.
2. With a view to simplify the Docker entrypoint, we’re not producing a zebrad.toml file or translating legacy Docker surroundings 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 era a part of the default zebra construct and have cleaned up zebrad/Cargo.toml to take away the getblocktemplate-rpcs function flag. Because of this, the next construct command is not supported: cargo construct --features getblocktemplate-rpcs
