I just wanted to make my geotagging CL work on top of master.
The offending commit is 38f10a7bd0f97475c2b876a7fde08e4ce47bf224 by the way:
all, testhooks: use sha224 by default, add hook for some tests to use sha-1
Apparently, there are no tests for switching to a new hash yet.
Maybe we should just switch back to SHA-1 as the default for the time being, or let the user choose the default hash.
Btw, I haven't found much info on the sha224 shift yet (other than stumbling upon the commit in question).
