I would like to announce that version 4.1 of vBulletin Publishing Suite and vBulletin Forum is now available. If you have an active vBulletin license, you can download your copy of 4.1 from the vBulletin Members Area at: http://members.vbulletin.com

Two items that we had envisaged to make available as 4.1
  • Updated Editor - to enable WYSIWYG editing in Webkit browsers (Chrome/Safari)
  • "Flexible URL Mapping"

Are not included in this release. Due to both the editor, and the flexible URL mapping affecting all aspects of our product, development and QA has taken a longer period of time than we had initially envisaged, and we are not sufficiently satisfied with the level of quality of either item to release them as features in their current state. Both items will be made available in future releases. We apologize in advance for any inconvenience this may cause.

Here is a list of the major features and/or bug fixes that are included in 4.1

Integrated, inline, single step installer/upgrader, a video of it in action is available here. Helps upgrading a board from vB version 3.5.4+. Supports upgrading via Command-line interface (CLI) for larger forums where a browser times out. Other changes center largely around the stability of the upgrade process and particularly the blog and cms installs which were brought in line with the more robust techniques of the VB installer.
Here are some of the larger install issues that we tackled along with the new install code:

Mobile APIs
vBulletin 4.1 includes APIs required to communicate with vBulletin's forthcoming Mobile Applications.
We have comprehensive developer documentation for these API's available here (at time of writing, documentation may not be 100% complete - please note "coming soon" sections)

Profile customization fixes
Here are some of the fixes to profile customization that are included:

CMS fixes
Here are some of the fixes included in 4.1 for the CMS:

Display Fixes
Fixes to the html/css to resolve cosmetic issues with the product, including rectifying some upgrade issues that occurred with vBulletin 4.0.8 upgrades with Custom Styles.

Misc fixes
Here are a number of the fixes made to everything else in the product:
