WordPress 3.5 has finally arrived thanks in part to the many people who have volunteered their time to make it happen. Over the next few days, users will be reporting problems and errors that they run into via the WordPress.org support forum. As with every major release, Ipstenu and the support team have put together a master list of issues being reported for WordPress 3.5. This thread is not meant to have any user feedback but is a curated thread that quickly highlights the known issues being reported as well as instructions on how to fix the problem.
As a side note, WordPress 3.5 continues the streak I’ve had in upgrading without any issues.
