Srini Kadamati

Apache Superset 1.4 is now released! This release contains:

  • a very large volume of bug fixes (the largest in recent Superset history),
  • enhancements in supported databases,
  • upgrades to the core user experience,
  • and many upgrades to the developer experience

In this post, I will focus on the first three. You can always browse the full changelog on Github. Let's dive in!

New Features

Certifiying Charts and Dashboards

Understanding which charts and dashboards are reliable, useful, and up to date is a universal challenge in BI tools. To help address this, you can now certify charts and dashboards and attach your name to it.

Certify Charts

This lets other users quickly glean which charts and dashboards can be expected to be maintained and reliable, and even filter down lists to just the certified ones.

Improved Dashboard Layout Capabilities

Tabs in Superset enable dashboards to be more dynamic and help dashboard consumers focus. To expand the capability of tabs, Superset 1.4 adds the ability to add tabs within Columns. Rows and columns are powerful containers in Superset for organizing charts.

Jinja templating lets you add more dynamic-ness to your dashboards. Superset 1.4 added support for referencing time_grain and time_column variables in your Jinja code.
