Contao 3.0.1 is available
by Leo Feyer – Announcements
Contao version 3.0.1 is available. The bugfix release fixed a couple of issues, including that page alias names could not contain Unicode characters anymore.
Also, with version 3.0.1 we have removed the automatic copyright notice in the front end according to the announcement of November 8th, 2012 and replaced it with a meta generator tag.
