After this change, - Symlinks on Windows are always unsupported. Sorry. - Symlinks are always enabled on other platforms. They are just a small file like anything else. There is no need to special case them. If you don't want to sync some symlinks, ignore them. - The protocol doesn't differentiate between different "types" of symlinks. If that distinction ever does become relevant the individual devices can figure it out by looking at the destination when they create the link. It's backwards compatible in that all the old symlink types are still understood to be symlinks, and the new SYMLINK type is equivalent to the old SYMLINK_UNKNOWN which was always a valid way to do it.
