There are a lot of b2g (aka Firefox OS) jobs that still run on Buildbot . Interestingly enough we had not tried before to trigger one with mozci. This release adds support for it. This should have been a minor release (0.8.0) rather than a security release (0.7.2). My apologies! All jobs that start with "b2g_" in all_builders.txt are b2g jobs that still run on Buildbot instead of TaskCluster (docs - TC jobs on treeherder).
