I just realized that the Confluence 7.11 → Confluence 7.12 upgrade is an AUI 8.3.5 → AUI 9 upgrade. Not some higher starting version like AUI 8.5 → AUI 9, as I had been assuming.
Therefore, I will be looking at ALL of the AUI upgrade guides for 8.x, not just the AUI 8.x to AUI 9.x upgrade guide that is referenced in Preparing for Confluence 7.12
There was a signficant change related to focus on checkboxes between AUI 8.3.5 and AUI 8.5 (AUI 9 Checkboxes in Confluence 7 Break Functional Testing Frameworks - #4 by daz). This is seen when going from Confluence 7.11 to Confluence 7.12.
That is what made me realize there is a piece of the puzzle missing in the Preparing for Confluence 7.12 document. That document only mentions AUI 8.x → AUI 9.x and skips mention of the 8.3.5 → 8.6 upgrade changes.
That checkbox change is not in the 8.x upgrade guides yet, but it will be when a AUI-5341 document bug is addressed. Anyways, there are plenty of other issues that ARE documented in the AUI 8.x upgrade guides and that should probably be mentioned in Preparing for Confluence 7.12
The “Preparing…” document should probably be more specific in the area of the AUI upgrade change.
AUI 8 upgrade guides
AUI 9 upgrade guides
btw, is there a reason that there is no mention of AUI in Confluence 7.12 beta release notes ?
I’m finding that the AUI upgrade in Confluence 7.12 is the most significant breaking Confluence upgrade I’ve seen (w.r.t. 3rd party plugins) since I started w/ a 3rd party app provider a few years ago. I think it is super important to get detailed AUI upgrade information out to everyone who is figuring out what Confluence 7.11 → Confluence 7.12 is going to mean to their apps because it’s a biggie.
