Hey Erik,
There’s a known issue and workaround with the AWS upgrade. See this post and let us know if that solves your problem. Upgrading from 1.5.9 to 1.6.10 on AWS Bitnami. Sorry about that, the upgrade issue on AWS will be fixed in the next release.
Also, stored procedures support did not make it into 1.6.10. It’s being implemented and tested now by the team. It’ll be live in a couple weeks when we push out the next release.
