Quartz and Ehcache versions supported

Hi,

What is the latest version of quartz and ehcache versions supported by spring 3.0.5?

From the deployed pom.xml the versions supported are 1.6.2 for both these libraries.

Is there any plan to upgrade these libraries to any of the latest versions(Quartz - 2.0.1 and Ehcache - 2.4.2)?

If there is any plans, when we can expect this?

Thank you
