why do you need to change this list at all?

[Navid Zolghadr, 2016/05/24 02:21:25]

I wasn't sure to be honest with you. The target seemed related and the fact that
other sources used in new tab page also listed here I thought I need to add that
here too. Didn't I need to? Should I just change this file to what it was?

[Dan Beam, 2016/05/24 17:20:46]

this is just annotating dependencies for closure compilation.  you're not adding
new types or anything, so I would revert this file

[Navid Zolghadr, 2016/05/24 17:51:14]

Done.
