 ## `Cargo` feature unification for `vergen` versions 8.3.0 and beyond
-`vergen` will accept `gitcl`,`git2`, and `gitoxide` as features.  If more than one of them is included, `vergen` will select `gitcl` before `git2` and `git2` before `gitoxide`.   If none are selected (for example, if you enable `git`, but don't select a backend feature), `gitoxide` will be selected.

 ## Notes about the optional `git2` dependency
 `git2` picked up some [security related features](https://github.blog/2022-04-12-git-security-vulnerability-announced/).  In docker environments especially, this requires a `safe.directory` configuration.   There are a couple methods for achieving this.
