Anyone know? Because I dont have these mods installed and dont really need to upgrade unless its critical.
This is mainly a bugfix with a few non-critical things patched. Since its not as severe need to upgrade, questions as the above are, obviously, expected.
Lets put it this way though, would you like to run the risk that one of these bugs (a few are to do with creating new sessions; the code failes to do that so you don't get logged in) could drive away a potential visitor? Or that these bugs could ruin your phpBB ExperenceTM
Also, if something goes wrong with your board, who's to say its not due to a bug that is fixed in 2.0.14? If you upgrade now, you won't have to answer that question.
There's no point sitting on sub-standerd software if the upgrade is not only free, but easy.
