vBulletin 3.8.1

3.8.1 PL1 has been released!

vBulletin 3.8.1 is the first maintenance release of the vBulletin 3.8 series. Maintenance releases will follow our scheduled release policy.

vBulletin 3.8.1 fixes a number of bugs found since 3.8.0 was released. Some of the issues fixed include:

* Rejecting a group transfer requests removes all transfer requests
* Profile privacy only hides information in limited cases
* Column mismatch when disabling social group messages
* Bad social group display when icons are disabled
* JavaScript error when dismissing a notice
* Social group icons not removed from filesystem/"new groups" list properly when deleted
* Birthdays shown on wrong day in specific cases
* Social group home page lacks proper float containment

A full list can be found in the bug tracker.
Social Group Subscription Temporarily Disabled
Due to confusion over the functionality provided, vBulletin 3.8.1 has temporarily disabled the ability to subscribe to entire social groups. You may still subscribe to individual social group discussions.
We are planning to improve this feature and re-implement it for the release of vBulletin 3.8.2.
If you wish to re-enable the feature yourself, you can remove the HTML comment around the "subscribe to this group" link in the socialgroups_group template.
Upgrading from Previous Versions
3.8.1 is a maintenance release. We recommend that all customers running prior versions of vBulletin 3.8 upgrade to benefit from bug fixes and stability improvements.
Full instructions for upgrading vBulletin are available here.
PHP and MySQL Requirements
Please note that vBulletin 3.8.x requires at least PHP 4.3.3 and MySQL 4.0.16 or later.
However, we recommend that vBulletin 3.8.x is run on PHP 5.2.8 with APC (or a similar opcode cache) and MySQL 5.1.30 for best performance and stability.
End of Life for PHP 4
PHP 4 has now reached its end of life. We strongly recommend that customers update their servers to PHP 5.2.8 if they are still running PHP 4. vBulletin 3.8.x supports PHP 5 without any problems, though you may need to disable strict mode for MySQL, see here on how to enable 'force_sql_mode'.
Note: We will continue to support PHP 4 in the vBulletin 3 series.
