Now Available: Meltano v1.39.0

Today, we are excited to release Meltano version 1.39.0, which (among other things) enables more streamlined and consistent configuration of all Meltano and Meltano UI settings using meltano config and the same highly flexible layered configuration model already used to manage plugin settings.

You can use meltano config meltano list (with meltano as the plugin_name) to list all available settings with their names, environment variables, and current values, or check out the brand-new settings documentation for more context and examples.

Excited to try it out?

To upgrade Meltano and your Meltano project to the latest version, navigate to your project directory, activate the appropriate virtual environment, and run meltano upgrade. This will upgrade the meltano package and apply any necessary changes to your project.

What else is new?

The list below (copied from the changelog) covers all of the changes made to Meltano since the release of v1.38.1 on July 3:


  • #2100 Let settings be stored directly in .env using meltano config set --store=dotenv
  • #2099 Let Meltano settings be configured using meltano config meltano {list,set,unset,reset}


  • #2100 Have meltano ui setup store secrets in .env instead of ui.cfg
