PR checklist

• For each library you've modified here, decide whether it requires a major, minor, or no version bump. (Click here for guidance)

If you're doing a major or minor version bump to any libraries:

• Bump the version in project/Settings.scala createVersion()
• Update CHANGELOG.md for those libraries
• I promise I used @deprecated instead of deleting code where possible

In all cases:

• Replace the appropriate version hashes in README.md and the CHANGELOG.md for any libs you changed with TRAVIS-REPLACE-ME to auto-update the version string
• Get two thumbsworth of PR review
• Verify all tests go green (CI and coverage tests)
• Squash commits and merge to develop
• Delete branch after merge
