October 2.0 was based off of the code base as of a year ago, so everything that was added to the project in the past year was removed in 2.0. As far as breaking changes in the 1.0 & 1.1 branches go the links are mostly talking about the docs changes that indicated the removal of the recent changes; but there are some that actually cause problems for current projects that aren't upgrading, such as the removal of the wikimedia-merge-plugin which is required for plugins to load their dependencies smoothly.

"If we discover what broke it, happy to backport the fix, but it appears broken due to some introduced reason that I'm not aware of

...

Please test in v2.0 and let me know if it still happens. Thanks"
