I am pretty sure that Smack will not be made available for Java 5, we will rather see a Java 7 edition. If you need a J5 version, you will have to recompile by yourself.
Walter is correct, I have no intention of going back a version. My apologies though for not putting that in the release notes for 3.2, that was definitely an oversight and I will make sure to not make that mistake in the future when we eventually move to version 7.
There are no plans to make that move yet though, as I don’t want to force users to move there yet.
