Merge #375

375: Prepare v0.7.4 r=thejpster a=adamgreig

I've created a new branch, `v0.7.x`, which is currently at the latest non-breaking commit (so includes #346 #349 #347 #351 #339 #352 #348 #363 #362 #361 but does not include #342), to track the 0.7 series since master now contains breaking changes for v0.8.

This PR (which targets the new branch) cherry-picks #372 #369 #374 and bumps the version to v0.7.4 (and updates CHANGELOG) ready for a new v0.7.4 release. Once complete I'll also backport the changelog entries and bump the version in master to 0.7.4.

I think this is everything that should be in 0.7 -- the only excluded PRs from master are #342 and #367 I believe, and I don't think we have any open PRs targeting 0.7 either.

Any other thoughts on items for inclusion in 0.7.4 (or other changelog entries I missed)?
