At the moment the maintenance process for SME 6.0 & 6.0.1 is being restarted.
The process is now documented at
http://no.longer.valid/phpwiki/index.php/Maintenance%20Process(If you have any questions after reading this then let me know so that it can be updated)
The updates will be available via yum.
At the moment there are mainly Fedora Legacy updates (undergoing verification), but more will be published.
Until now it has not been widely published as there have been no verified updates, but thanks to encouragement from Charlie and the hard work of a few community members a large number of packages will be moving from updates-testing to updates.
Once there are packages in updates they will be more widely advertised. Please be patient just a little bit longer.
It is the intent of the maintenance team to have all updates available from the yum repository. The maintenance team is currently working to prepare the next batch of updates.
Please let me have all comments (and volunteer help if possible).
If you find any problems with the updates please make that known in the Bug Tracker - there is an entry for every update that the maintenance team has handled.
