As of ~last year they changed the support and release cycles for Vault/Consul/Nomad so that security and bug fixes are only released for the latest minor versions outside of Enterprise. Every community release is deprecated the moment a new one is released and there are no backports or LTS.

This means that since then you are frequently faced with the choices of 1) keep up with the latest version, facing frequent regressions and occasional breakeage depending on what functionality you depend on 2) stay behind on versions with known bugs for a while after each minor release 3) build your own fork allowing you to pull in patches as necessary
