The **nightly** private image is now called **alpha** , its DockerHub tag is `simplicite/platform:alpha` (it replaces the former `simplicite/platform:nightly` tag), it corresponds to the latest changes done on the platform, it will be built and pushed up to several times a day (but more likely once a day as used to be the nightly built). Be careful that this built may be rather unstable, so use it only for preview purposes. A new **beta** private image is now also made available each time a reasonably stable state is reached, its DockerHub tag is `simplicite/platform:beta` it will be built and pushed once a week or so (in prerelease phase). It should be suitable for testing and development keeping in mind that it should not be used to production (for which you must use release images instead). ![image](https://community.simplicite.io/uploads/default/original/1X/6eae015e4b61a03c99e829a754b3ecb39178eb97.png) Both alpha and beta images are based on the public server image `simplicite/server:centos` No changes on the **release** private images. The correspondance between Git branches and Docker images is as follows: | Git branch | Docker image | | --- | --- | | `master` | `simplicite/platform:alpha ` | | `prerelease` | `simplicite/platform:beta` | | `release` | `simplicite/platform:latest` | --- _[View the full topic](https://community.simplicite.io/t/branches-and-docker-images/981)._
