There are probably almost as many conventions as there
are software packages. However, it is important
to use or should use one conventional release numbering
scheme for all the EPICS software packages.
One of advantages of this is that we can easily know what
level of differences between current release and new
release, like major architechtural changes or
existing feature enhancemenets or bug fixes before
we attempt to upgrad one software package.
Here is the outline of the scheme which follows the
Berkeley CSRG version numbering scheme:
X.Y.Z
where X is the major release number.
We increment this number whenever we make major / architectural
changes. It usually means the new release may not backward
compatible.
where Y is minor release number.
We increment this number whenever we make new features or
existing feature enhancements. It usually means the new release
should be still backward compatible.
where Z is sub-minor release number.
We increment this number whenever we generate a release of bug fixs.
It also is known as a "patch" release.
GNU-isms also use alpha, beta releases for pre-production releases.
It often presents in two forms: X.Y.Z.nn or X.Y.Zalpha.n, X.Y.Zbeta.n
Any comments ?
