v3.5.0 (2024-07-23)

• Docker Hub 🐋
• PyPI 🐍

Highlights

• Plugins are now auto-installed when commands require them. This change involves two new features:

  • New CLI options:
    • --install
    • --no-install
    • --only-install
  • A new project-level setting auto_install. The value of this determines whether plugins are auto-installed when none of the above options are passed (the default). Set it to false to require --install to auto-install plugins.

  There are some known gaps that will be addressed in future releases, give them a 👍 to let us know they are affecting your use of this feature:

  • #8660

  Thanks to @ReubenFrankel for contributing this to Meltano!

• A new CLI option --refresh-catalog and plugin-level extra use_cached_catalog. Use this if you need the extractor's catalog to reflect changes that occurred upstream, like often happens with database sources.
