Just a quick note, but we have not yet released beta 2 compatible ZIPs of the ActionScript 3 libraries that we released with beta 1. We need to track down a couple of issues before we can rebuild the zips.
This means that you cannot use the library SWCs in the beta 2 builds of MXMLC or Flex Builder. However, the actual source for the libraries have been updated to beta 2 (Flickr still has one or two issues), and thus you can grab the source, and link against that (just add to your classpath).The libraries include:
- RSS / ATOM
- General Utilities / security hashes / JSON
