The point was brought up that some recommendations that the working group
forms will be jarring for APIs to implement when going from vN.* to vN+1.0
for both developers and consumers. Client libraries often provide
compatibility (or upgrade-path) versions to help bridge the gap between
going from vN.* to vN+1.0. As a group, we’re looking for feedback from the
developers on the following topics:
- Does this seem preferable?
i think it's a really nice idea to have some sort of guidelines to
assist with the development of compatibility version. i know i would use
- Does it sound reasonable and maintainable?
good question, my fear would be that we would start strong but fade once
more than a few versions were published. having a clear procedure for
updating and maintaining the guidelines might help.
- Does it seem reasonable as a way of improving user experience and
for me, yes.
If you have a positive feeling for this idea, there are a couple
- Should the API WG recommend a strategy for this versioning path?
- If so, should the versioning path work like:
- vN.M -> vN.99 -> vN+1.0
We would use .99 to indicate that you it’s compatible with vN.* but
also provides information/endpoints in vN+1)
- or vN.M -> vN+1.0 -> vN+2.0
In this case we would make N+1 be the compatibility version (perhaps
do not allow increments of the minor version) and N+2 would be the version
of the API that is fully in-compliance with the Working Group’s final
this is an interesting idea. i think it would be nice if we could
develop something that would be a clear indication to developers exactly
which version and capabilities an api is presenting.
of those two options, i'm leaning more towards the vN.99 approach.
thanks for bringing it up Ian!
