 ## Versions
 
 This `main` branch of this repository will always point to the latest numbered release of the devcontainer image. This image will contain specific, numbered releases of the various tools as documented above. If the devcontainer is updated with non-breaking changes, the minor version number will be incremented. This gives reassurance that, say, a v1.7 devcontainer will contain tools which can compile programs made with a v1.2 devcontainer without issue.
