# 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 [https://miller.readthedocs.io/en/main](https://miller.readthedocs.io/en/main) contains information for the latest contributions to the [Miller repository](https://github.com/johnkerl/miller).

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.
