TFU/JFU 2.14 for Joomla 1.5.x and 1.6.x are now released.
simply go to the website and get the latest version. Ther you also find the main changes. For details always check the history in the packages.
I have also reworked the FAQ of TFU. You now have howto 19 which helps you to understand error messages better which are caused by the server.
WFU 2.14 is almost ready and you can already download the 1.8.5 preview in the forum. You can already use 1.8.5. I currently only do some internal stuff.
Have fun using TFU,JFU,
