Arduino 1.5 beta libraries

It looks like this download for 1.5 (found here: Arduino - Home) does not have the same contents in the ‘Libraries’ folder as what came in 1.0.1. For example the ‘SD’, ‘Servo’, or ‘Ethernet’, etc. libraries. Are these built into 1.5 somehow?

hello,

don’t know the reason for.

They might be specific to the AVR platform and not compatible with the SAM one.
