Slackware has released their new ports, called Slackware64 which has been tested internally by the Slackware crew and now it's ready for public testing. The port is synced with Slackware-Current development, so everything goes into Slackware-Current will also go to Slackware64-Current as well. This has been posted at LWN and i think it will be arriving at DistroWatch shortly
The news also confirms that the next Slackware release will be 13.0. It will contain lots of changes from the current 12.2 release. More about development on -Current can be viewed on their -Current changelog.
Great job to Slackware crew and of course, Patrick V.
