I renamed 2.147 into 2.010.1. We were going back and forth in version numbers (according to version-satisfies) between 2.1xx and 2.0xx, and at least that's stopped. We now have quite a few unstable 2.1xx releases in git with the "wrong" order, but presumably the few people who use asdf from git will know to upgrade from git and won't have trouble with it. Maybe I should have been more daring and have used 2.0.10.1, but that would have meant out-of-order versioning amongst stable releases, too, and that would have been more problematic.
News: as compared to 2.010, 2.010.1 mostly works fine on GCL 2.7, except that GCL 2.7 has problems with condition handling (at least in the version I have from debian).
