@jrasell could you please help with it?

It looks like updating to 0.9.6 was not sufficient. I'm receiving the same error:

[ERROR] levant/command: error parsing 'job': 1 error occurred:

* group: update -> invalid key: auto_promote

@andyghiuta I will need to release 0.2.9 in order for the vendor change to take affect. You can build master locally if needed in the meantime. I hope to find time to perform the release this week, hopefully tomorrow.

Ah, right... I was looking at the 0.2.8 release date (14th) and thought "that was 11 days ago, when this was closed.". I forgot to check the month too. Monday... 😬

@jrasell I tested a build from master and it works as expected. An official release would be much appreciated. Thanks!
