Documents for releases

If your mlr version says something like mlr 6.0.0-dev, with the -dev suffix, you're likely building from source, or you've obtained a recent artifact from GitHub Actions -- the page contains information for the latest contributions to the Miller repository.

If your mlr version says something like Miller v5.10.2 or mlr 6.0.0, without the -dev suffix, you're likely using a Miller executable from a package manager -- please see below for the documentation for Miller as of the release you're using.
