Posting in the Magento forums has been disabled pending the implementation of a new and improved forum solution which should better serve the community.
For new questions please post at magento.stackexchange.com, the community-run support site for the Magento community. We will be providing updates on the new forum solution soon. For questions or concerns please email email@example.com.
The released 0.6.14100 packages still use the single main.xml layout file at the moment. But this gonna be changed in the next release to give users much more flexibility when installing/upgrading new modules. We’ll update the community as soon as it is changed.
