We are now on MediaWiki 1.25 deployment branches of core.  For Wikibase / Wikidata branches, we are using a new naming scheme:

Instead of "mw1.25-wmf1" as in the past, we now have "wmf/1.25wmf1" which is the same naming scheme as used by core and other extensions.

This allows Jenkins to test our branches against the corresponding version of core, if available, instead of testing against master. Thanks to hashar for making this possible. :)

Cheers,

Katie
