I don’t have an answer about the beta URL at this time. I’ll ask the Connect team.
My assumption is that it was created for 1.2 to get vendors building for the new Act as User functionality and is still available. It looks as though the “beta” URL has the same content as “latest”.
1.2 seems to be a bit down the road at this point as I am seeing 1.2.35 in my developer instance.
I got caught out when I used AP.flag and AP.dropdownList in my add-on. It worked fine on the development instance of JIRA Cloud that I was using; but when I ran up a new testing instance of JIRA Cloud, I discovered that AP.flag and AP.dropdownList are not present.
That said, I’ve just checked the system add-ons. Both dev and test are using version 1.2.35 of the Atlassian Connect Plugin. It’s a mystery.
Thanks for the clarification, Dave. What I understood to be a delay in the rollout of Atlassian Connect 1.2 was really a delay in the rollout of ACJS version 5.
