Now Available: Meltano v1.49.0

Today, we are excited to release Meltano version 1.49.0, which (among other things) standardizes on <PLUGIN_NAME>_<SETTING_NAME> for configuration environment variable names (e.g. TARGET_POSTGRES_HOST for target-postgres‘s host setting instead of PG_ADDRESS), makes environment variable expansion in setting values more flexible, and uses this to let you easily override your extractor’s load_schema.

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.
