Assigning to hashar since he's running the train (tomorrow).

Tentatively closable, then?

never say this again :P

I have sent the dummy change https://gerrit.wikimedia.org/r/#/c/268096/ against MediaWiki core 1.27.0-wmf.12 and the tests are all fine (except phpcs but that is due to the dummy .php file being empty).

We had Wikidata cut of either the old 1.27.0-wmf.10 or master branch. https://gerrit.wikimedia.org/r/#/c/268100/ tweak the submodule to point to Wikidata 1.27.0-wmf.10.

hashar set Security to None.
