### Available image tags
Currently we only handle a rolling release of new versions so only _latest_ tag is available, but there is [work in progress](https://github.com/juanluisbaptiste/docker-postfix/pull/29) to start releasing versioned images to be able to pin to specific versions in production deployments.
We use semantic versioning for this image. For all supported architectures there are the following versioned tags:
* Major (1)
* Minor (1.0)
* Patch (1.0.0)
Additionally the amd64 architecture has the following tags:
* _latest_
* _alpine_
*_NOTES_*:
* The _alpine_ tag has been switched to use the master branch, but it's irrelevant as it is the same as _latest_.
