Building Meltano in Public: Six-weekly Recap

Last week, it was once again my turn to host a GitLab Group Conversation (a publicly live streamed Q&A on the GitLab Unfiltered YouTube channel) on Meltano!

I used the opportunity to share a recap of:

Group Conversation Presentation

5 releases since the last GC (2020-10-07)

  1. V1.54.0 ensures arbitrary environment variables defined in .env are passed to invoked plugins, recreates plugin virtual environments when running meltano install to make sure the latest versions of dependencies are installed, and bumps the Airflow version to 1.10.12.
  2. V1.55.0 adds out-of-the-box support for the datamill-co and transferwise (aka PipelineWise) variants of target-snowflake. The datamill-co variant is recommended for new users and is now the default, but the original meltano variant is still supported. 
  3. V1.56.0 adds out-of-the-box support for the BigQuery destination using the target-bigquery loader, as well as official support for Python 3.8 alongside 3.6 and 3.7! 
  4. V1.57.0 adds out-of-the-box support for the PostgreSQL and MySQL/MariaDB data sources using the transferwise (aka PipelineWise) variants of tap-postgres and tap-mysql.
  5. V1.58.0 lets you disable autoscrolling in the pipeline log UI, fixes incorrectly disabled Test and Save buttons in the plugin configuration UI, and fixes logging in using Google Chrome when the UI is not served over HTTPS.

(Yesterday, we also released V1.59.0!)
