Singularity 3.0.0 Beta 1

Greetings Singularity Folks!

It is our great pleasure to announce the v3.0.0-beta.1 Singularity after many months of work. This release again contains major bug-fixes, improvements, and enhancements when compared to v3.0.0-alpha.2. Further, we feel that this release achieves feature parity (with some minor differences here and there) with the 2.x versions of Singularity. We anticipate that all major features have already been committed at this point, and thus all development for the rest of the pre-release of v3.0.0 will be geared towards catching and fixing bugs.

It would be greatly appreciated if everybody in the community could spend as much time as possible trying to break this release. If you do happen to notice anything that doesn't seem right, something that works in 2.x but isn't working now, or any other minor bugs/problems, please let us know on our slack channel or on the Issues Tab of the Singularity repository.

A full changelog and release notes for everything being introduced and changed in v3.0.0 will be available when we officially tag the v3.0.0 release. For the time being, you can refer to this blog post by @ArangoGutierrez about what we expect the release to look like.

Known Issues:

• Zypper bootstrap does not work correctly in some scenarios
• %files section is not supported when building remotely via the Sylabs Remote Build Service
• The command singularity help ... always returns 0, even when attempting to get help on a non-existent subcommand. This behavior is different from 2.x
• Similarly, the command singularity instance list now returns 0 even when no instances are running on the system.
• The command singularity inspect does not yet provide inspection for individual apps, only the base image

Over the coming weeks, we will be tirelessly squashing bugs to ensure the most stable release of v3.0.0 possible. Stay tuned, and as always, we welcome your feedback and contributions!
