I just finished the system update of my server.
Now this wiki used Binky RC2, PHP 5.5.6 and the latest BlogTNG.
The main advantage of the latest BlogTNG is that it now uses the sqlite plugin. Therefore you don't have to use the sqlite3-branch of BlogTNG like described by Seiichriro.
I haven't found any problems so far.
If you see any feel free to post about them in a comment here.
