Parsley 3.0, Data Binding and IOC

Hi, we have an existing Flex app, described in a prior posting, which uses
Parsley mainly for Data Binding, and also for IOC.

We are currently using Parsley 2.4, though Parsley 3.0 seems to be the
latest release.

The project appears to be dormant.

My question is this:

1) Are there any problems using Parsley 3.0 with modern SDKs or Players ?

2) Are there alternative Data Binding libraries which are preferable and/or
are still being supported ?

Thanks

David
