Create a release

[jecisc]

It would be great to have a release of Garage to be able to point to a stable version instead of a branch that might break in the future.

Is a release planned?

@estebanlm ? I'm not working on this actively, but if somebody asks me, I'd say that we make tests run on Pharo7 first. They are probably broken because of the changes on the test runner killing processes.
