Redash v8.0.0-beta Release Notes

Release Date: 2019-08-18 // almost 3 years ago
  • ๐Ÿš€ After months of being heads down with hard work, it's finally time to wrap up the V8 release ๐Ÿคฉ This release includes many long awaited improvements to parameters, UX improvements, further React migration and other changes, fixes and improvements.

    While this version is already running on the hosted platform to make sure it's stable, we're excited to put this in the hands of our Open Source users.

    ๐Ÿš€ Starting from this release we will no longer build a tarball distribution of the codebase and recommend everyone to switch over to using our Docker images. We're planning on dropping Python 2 support towards its EOL this year and switching over to the Docker image will make this transition much simpler.
