Parent task to keep track of issues and schedule of superset upgrades.
**Current version deployed**: `0.26.3`
Outstanding issues:
* From version 0.28.1 onward Superset requires Python 3.6, ~~a version not present in Debian Stretch (max 3.5)~~. The SRE team introduced a special apt component to have Python 3.{6,7,8} on stretch with https://gerrit.wikimedia.org/r/#/c/operations/puppet/+/480041.
* Version 0.28.1 introduced several bugs that affect the UI experience, that hopefully should be fixed with 0.29.X. We tried to deploy 0.28.1 but we rolled back after a few hours, so **we are going to skip the update to this version**.
* The Analytics team needs a "staging" version of superset (with a proper database) to test upgrades and possibly allow people to test their dashboards etc.. before the upgrade becomes the current version of superset.wikimedia.org. This is currently tracked in T212243
Superset releases: https://github.com/apache/incubator-superset/releases
**Current upstream status**: 0.29 is still on hold due to Apache license issues (https://github.com/apache/incubator-superset/issues/6785)
**What is the Analytics team working on**:
* creating a staging/testing environment (T212243) and possibly test 0.29rc7 on it.
