The Simple Streams README says about that:

  * version_name:
    A 'version' of a product represents a release, build or collection of
    that product.  A key in the 'versions' dictionary should be sortable
    by rules of a 'LANG=C sort()'.  That allows the client to trivially
    order versions to find the most recent.  Ubuntu uses "serial" numbers
    for these keys, in the format YYYYMMDD[.0-9].

json files for Ubuntu and CirrOS images uses this format, although
it seems to not be a strict rule.

Hm so you are suggesting to just make the revision internally as string
(but still forcing an integer in native indexes)? That would work too,
I guess.

Thanks,
