Compatibility with previous versions1 user found helpful
I'm working on making my add-on's (Advanced Forms and Data Display) compatible with 5.5, which is proving to be a little more time-consuming than I had hoped. This is fine and I certainly want to get this taken care of, but my question is, what are you guys doing about previous versions of C5? Are you maintaining compatibility with those too? Or as you update your add-ons (with say, new features) are you only applying those updates to the 5.5+ version of your add-on?
The reason I ask is because I already have enough trouble staying on top of feature and support requests. Having to maintain one version for pre 5.5 and one version for 5.5+ just seems like it would be a HUGE headache. Any thoughts?
All that being said, my addons are not as complicated as yours (except maybe Designer Content, for which I did the forking thing and will no longer be putting any work into the 5.4- compatible version).
For Magic Heading I added 5.4/5.5 conditions that switched default scraping selectors between Plain Yougurt and Greek Yogurt.
For Zone Based Shipping the C5.5/eCom-2.5 shipping edit interface was not a big enough panel, so I moved the whole interface to its own dashboard page and made the eCom shipping interface a trivial 'See other page'.
All now have a single version for both forwards 5.5+ and backwards 5.4.x compatibility.
But then none of my addons have difficult interactions with C5 itself such as using scrapbooks or creating/modifying page types and pages.
