If you're running version 5.1.0 or later, feel free to use the Auto-Upgrade Procedure for a quick and automated upgrade.

In any case, all the upgrade options are outlined here: Upgrading an existing installation.


  • If you have been using previous v6 beta versions, you should delete the boostrap_* skin folders before installing this version. Otherwise you will have old files interfering with the new ones.
  • Many root files are no longer needed in this version and should ideally be deleted from your web server.
  • You should use the provided tool to convert your database to UTF-8. Please check Upgrade to b2evolution version 6.x for instructions.


In addition to features of version 6.6.3-stable:

  • More than 100 small bug fixes and visual improvements.
  • Force IE rendering to Edge by default <meta http-equiv="X-UA-Compatible" content="IE=edge" />
  • Outgoing proxy server support.
  • On new installs we now create an "Editors" group (instead of "Trusted users" which had little meaning).
  • On new installs all collections accept subscriptions by default.
