Uhh, 12-18 months maybe? There was the wild west of v25(?), 26, 27, and 29 that were much more frequent because they were adding new hardware support rather than new features. I think they considered v24, v28 and v30 major releases that were probably on the 12-18 month schedule, the in between versions were sprinkled in there.

It was explained to me in a class I took a couple years ago, by Rockwell people, that every 4th version is what they call a "PIN" version and that is what you should use unless you need feature/hardware support from one of the intermediary versions. PIN versions are V24, V28 and V32.
My usage of "major" vs "minor" releases was only point out that there were some major versions that were released at an unusually rapid paste (< paste? [facepalm]). When Rockwell would talk about them, they would often talk about v24, v28, v30, v31 and v32 as part of their normal release cycle, while suggesting not to waste your time with the other versions unless you needed to use the hardware those releases were targeting. The v26, v27 and v29 releases still followed their rule "install each major revision of software for each major revision of firmware you want to support"
