1. Plugin things should all be prefixed by `Plugins:` then the name of the plugin altered.
2. New config options should always be named in CHANGELOG.md!
3. Unify groups of changes into a single line, in this case, GRPC.
4. Command, plugin and option names are in backticks.
5. Offers changes are still under EXPERIMENTAL.
