[Bayonne-devel] About version numbering in Bayonne 2

[David Sugar]

Since our version numbers are a bit high in Bayonne2, I thought I would 
comment about how things are versioned.

First, as I use C++, its rather easy to modify a class such a way that 
it breaks binary compatibility with previous releases, either because 
the object size has changed, or a new virtual has been inserted. 
Generally, "abi" changes that break binary link compatibility with 
previous versions are given a new major.  Hence, this can be expected to 
happen rather frequently, especially in early development.

Sometimes I will bump a version around a major functional 
reorganization.  Hence, what is different between 0.6 and 0.7 was in 
part the seperated libexec.  This I think is the sort of thing people 
most often expect version changes for.

Given this, it would be mistaken to believe that versions represent 
feature completeness, or can be used to estimate how many versions there 
are until a 1.0 release of Bayonne 2.  I would estimate that its current 
completeness might be closer to where Bayonne was at 0.3-0.4, although 
it is quite possible to have a very solid release of Bayonne2 by the end 
of the year based on current progress.
