Thunder Beta syntax error on transaction {}

There doesn't appear to be a separate beta forum, so I'm reporting this here.

Testing the Thunder Beta, it reports the following as a syntax error:

if (thing) {

     transaction {

          doStuff;

          EntitySave(item);

     }

}

It reports 'return statement in function' for pretty much all our cfscript transaction statements.

This is the standalone install. I haven't been able to get the Eclipse plugin install working yet.
