What is the convention if multiple releases have to occur more frequently than the resolution of $AGE. That is, a month.  For instance if release the first update to 18.3 is 18.3.1 what happens if immediately upon release a major regression is found? This could not be 18.3.2 - unless it was artificially held to be released in May. Would it be 18.3.1.1?
