I wouldn't expect that to have changed at all.

It depends on what you want exactly.

No.  No, there is no special support for symbolic links in <tar> yet.

To detect symlinks Ant compares canonical and absolute file names,
which may lead to false positives on a larger set of non-Unix OSes and
even on some Unix OSes (like Macs using HFS+).

The <symlink> task uses ln as native executable instead of JNI, this
makes distributing Ant a lot easier (otherwise we'd have to create and
maintain platform binaries for all OSes that support symlinks).
