A first usable alpha version of Grid Elements 2.0 is now available in our repository http://forge.typo3.org/projects/extension-gridelements2/repository/show?rev=2-0
The PHP error message regarding problems with namespacing and the way the TYPO3 6.0 core is implementing hooks are now gone, even for users of Debian systems.
As we already announced, we decided to deactivate the drag 6 drop methods of the TYPO3 core. Additionally there were some changes to the original layout of the page module, for example to reduce the extreme spaces between columns and above column headers.
We would higly appreciate if you could test this version already and report potential bugs at http://forge.typo3.org/projects/extension-gridelements2/issues, while we will go on fixing the known problems.
We'll stay tuned!
