Preparing for Indigo Sync 2019-03-19

Indigo Maintainers,

We’re due for another sync. We currently have 33 packages ready for sync and one regression that I have just rolled back since it looks like it might just be a backport that needed newer dependencies.

I will plan to hold new releases and do the sync at the end of this week. If there’s anything that should be considered relating to this plan please reply here.

The sync is out:
