Now Available: Meltano v1.42.0

Today, we are excited to release Meltano version 1.42.0, which (among other things) makes meltano elt and its state management more resilient to failure and interruption:

• #2147 Continuously persist state messages output by loader (forwarded from extractor) so that subsequent runs can pick up where a failed run left off
• #2180 Mark pipeline job as failed when process is interrupted (SIGINT) or terminated (SIGTERM).
• #2166 Don’t fail on large extractor state messages by increasing loader output buffer size from 64 to 128KB

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.
