mojoPortal 2.1.6 is now available from the download page.
This release adds a new Site Statistics Module and some bug fixes.
This will be an easy upgrade if you are running mojoPortal 2.1.x with no custom modules of your own because there are no schema changes in the db. If using MS SQL or PostgreSQL you need to re-run the script that creates stored procedures.
If you have custom modules you have implemented yourself, you should test your code with the latest source code. There were some major namespace re-organizations that may have broken your custom code. See my previous blog post, and if you need help changing your code so it works with the new changes in mojoPortal, please post in the forums and I will try to help.
If you have custom skins, you may also need to tweak the css for the menu, see the included skins css files for changes I made there.
As always be sure and back up both your db and your site before attempting an upgrade. If you run into problems post in the forums and I will help.
