Hello Gatherlings and other folks who may or may not be interested,

Today Gather's 1.26wmf3 deployment branch was updated to master and deployed to wikis running 1.26wmf3.   Tomorrow en.wiki is riding the deployment train and all wikis will be updated to wmf3 [1]  So our latest changes will be reflected then.

The reason we cannot deploy master to wmf2 today is because of the API change [2].  This change is not backwards compatible, therefore cherry-picking it to wmf2 would in no doubt have had unforeseen complications with other extensions / core components on wmf2 deployment branch.

Core changes like this with massive deprecations / non-backwards compatibility while rare, is a battle we face when doing weekly updates.
