A note on calc release numbers

Or, why Fedora may not always have the exact latest version.

The upstream Calc project uses a somewhat unusual scheme for "stable" and "unstable" releases that is independent from the x.y.z.p numbering scheme.

The version number scheme is basically as expected; the more-significant places are incremented on bigger changes. But, at any given time, any version can be declared either stable or unstable, depending on how much testing the authors feel that particular release has gotten. The only way to tell is to look at the #.#.#.#_IS_LATEST_STABLE or #.#.#.#_IS_LATEST_UNSTABLE files in the archive at http://isthe.com/chongo/src/calc/.

In general, I try to skip the unstable releases entirely, but occasionally will update to one of them in Rawhide if the change looks small and the release based on that Rawhide is a long way off.

Modular Future?

In the future, I may make "stable" and "unstable" branches available, following the upstream guidance.
