Now Available: Meltano v1.35.0

Today, we are excited to release Meltano version 1.35.0, which (among other things) makes it easier to manage and version control a Meltano project’s configuration by having meltano config store values in meltano.yml by default, instead of the system database.

Sensitive and environment-specific values can still be stored in the system database via the UI or meltano config <plugin> set --store=db <key> <value>.

Excited to try it out?

To upgrade your local installation of Meltano, activate the appropriate Python virtual environment and run meltano upgrade from inside a Meltano project, or pip3 install --upgrade meltano from anywhere else. If you’re running Meltano inside Docker, run docker pull meltano/meltano.
