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). From https://github.com/apache/incubator-superset/blob/master/UPDATING.md it seems though that the dev team already reached 0.32, but everything is blocked by the aforementioned licensing issue. I'd expect 0.29/0.31/0.32 to be released all together when proper licensing is applied.
UPDATE: it seems that proper licensing has been applied, in theory we should start seeing more regular releases very soon. We are still trying to work with upstream to fix the issues listed below but they are a bit slow to acknowledge/answer/accept-pull-requests/etc..
**What is the Analytics team working on**:
* creating a staging/testing environment (T212243) and possibly test 0.29rc7/0.31.0rc18 on it.
