Difference in Mule 2.2.x and Mule 3.0

Hello,

Apart from hot deployment, what is the difference between Mule 2.2.x and Mule 3.0 series ?
Specially some high level architectural insight would be helpful to community.
Is it a same code base or drastically different code base ?
What tech we are using to achive hot deployment some third party or mule custom code ?
3.0 is having osgi features ?

Regards,
Manoj
