• the 5 releases we’ve had since the last update 2 months ago,
• 17 recent contributions made by 9 community members,
• other exciting recent and ongoing developments,
• recent and projected weekly Slack activity,
• that week’s priorities, and
• a list of upcoming priorities.

If you’re curious, check out the presentation on Google Slides and the Q&A on YouTube. The presentation content is also reproduced below, as is an embedded video of the Q&A!

With Douwe Maan, that makes 3 full-time Meltano team members!

5 releases since the last GC (2021-01-14)

1. V1.66.0 prevents pipelines from getting stuck in the “running” state forever when their meltano elt process is killed unceremoniously by the operating system or some other mechanism.

2. V1.67.0 fixes two bugs with meltano schedule run <name>: if the schedule’s meltano elt command fails with a nonzero exit code, it now does as well, and it no longer requires the meltano executable to be in the PATH.

3. V1.68.0 adds support for entity/attribute selection to tap-gitlab and bumps Airflow to version 1.10.14.

4. V1.69.0 adds out-of-the-box support for the Quickbooks source and adds support for Airflow 2.

5. V1.70.0 prevents two pipelines with the same Job ID from running at the same time, adds out-of-the-box support for the Chargebee and Sage Intacct sources, and fixes a bug that prevented Meltano Analyze from working with custom plugins.
