V8 Beta is here! 📦

After long months of intensive work and contributions from 46 people :pray: , we are happy to present a beta release of V8.

We actually created the first release a month ago, but then found a few issues we wanted to fix before announcing it, and here we are… This beta version should be stable enough for general usage (this is what powering the hosted service), but use at your discretion. If nothing major if found in a week we will make a final release.

Upgrading

Docker Tag for this release: redash/redash:8.0.0-beta.2.b29352.

See documentation on how to upgrade.

Please note that starting from this release we’re no longer build the tarball version of a release – only Docker images. This of course doesn’t prevent you from deploying Redash anyway you want.

So What’s new in V8?

    • Support for multi-select in dropdown (and query dropdown) parameters.
    • Support for dynamic values in date and date-range parameters.
    • Search dropdown parameter values.

  • User can now regenerate Query API Key.

Other Changes

  • Add options for users to share anonymous usage information with us (see docs for details).

  • Support multi-byte search for query names and descriptions (needs to be enabled in Organization settings screen).
  • CSV query results download: correctly serialize booleans and date values.
  • Dashboard filters now collect values from all widgets with the same filter.
