- Datalad version 0.13.0 or later is now required.
- In the upcoming 0.14.0 release of DataLad, the datalad special remote will have built-in support for "shub://" URLs. If `containers-add` detects support for this feature, it will now add the "shub://" URL as is rather than resolving the URL itself. This avoids registering short-lived URLs, allowing the image to be retrieved later with `datalad get`.
- `containers-run` learned to install necessary subdatasets when asked to execute a container from underneath an uninstalled subdataset.
