We're happy to announce the release of vBulletin 4.0 Beta 5.

The reason this release has not been designated a release candidate as originally planned is that it includes several new features, including:
  • improved RTL support for Arabic and Hebrew
  • an enhanced site map for CMS and Blog
  • additional style vars for Forums
  • ... numerous new bug fixes, and more.
These features require a proper beta cycle, hence the B5 designation.

Please see Don's blog post for additional details.
