4.1.2
The only changes in 4.1.2 are related to renaming the repository in a way such that "jaxb2" is replaced by "jaxb" everywhere to make sure people understand that JAXB 2 isn't supported anymore. Documentation has been updated accordingly.
If you are using binary artifacts from maven central, please be aware that their names have changed, too: jaxb2-richt-contract-plugin has been renamed to jaxb-rich-contract-plugin.
