Software Version Numbering

Hi folks,

Does anyone know if there are any standards, ISO, IEEE etc, on the topic of software version numbering or if this topic is included in any other standards?

I'm not aware of any standards, but when I worked in software QA our system went something like this:

1 - new software, initial release (after beta testing)
1.1 - v.1 with some quick bug fixes
1.1.1 or 1.1(a) - v.1.1 with minor enhancements and/or bug fixes
1.2 - reasonably substantial upgrade, but not a major rewrite
etc., etc.

2 - major rewrite/upgrade
2.1 - as above
2.1.1 or 2.1(a) - as above
etc, etc.

Hope this helps.

Are you referring to software versioning?

Yup thats exactly what I'm referring to. We're just finding the current structure of major.minor.patch doesnt meet our requirements so before we come up with our own custom numbering system I thought I would see if any standards on the subject exist. From the results of my google searches it would appear as if there are not any but thought it was worth checking on here to see if anyone was aware of any.
