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 6.6.8-stable:

  • Better display of dates and user names in the Bootstrap Forums skin.
  • GeoIP.dat can be auto-update if just this one file has write permissions (instead of a whole directory)
  • Better compatibility with PHP version 5.2 (especially in the upgrade script). (Note: for PHP 7 compatibility, please use b2evo v 6.7+)
  • Suppressed some annoying warnings on some hosts that have PHP ini_set() disabled.
  • Fixed block caching for Item specific widgets.
  • User interface polishing (read: we fixed some dirty CSS ;)
  • Stability improvements (read: we fixed some bugs that should have fixed a long time ago already ;)
