Hi,
this is just a short note. It seems that the subversion servers from sourceforge are down at the moment. This means, that neither commits nor checkouts are possible for TYPO3Core and TYPO3xdev.
[UPDATE] There is now an official statement from sourceforge. Due to some hardware faults, the svn repositories for projects with first letter a, f, l, m, t, y, and z are not available. (see here)
Greets,
Thomas
