0.11.0

Apr 25, 2017

New Features

Behavior Changes

  • PIO-25: pio-start-all will no longer start PostgreSQL if it is not being used.
  • PIO-47, PIO-51: pio build no longer requires access to the metadata repository. pio commands will now accept an optional --engine-dir parameter if you want to run pio build, pio train, or pio deploy outside of an engine directory. This is an interim solution before an engine registry feature becomes available in the future.

  • PIO-54: New generated access keys will no longer start with a - character.

Other Changes

  • PIO-28: Code refactoring of the command line interface. It is now possible to develop new interfaces that perform the same functionalities provided by the CLI.
  • PIO-53: Integration tests can now be tied to every single Git commit, without the need to update the official test Docker image.
  • The meta data and model data access object methods are now public and marked as Core Developer API.
