libftdi-1.0 has not been formally released. So I think all the major
distros will stay at 0.18 for a while.

As for why to switch to libftdi-1.0, the main reason is the real async
support since it is based on libusb-1.0.

UrJtag has already switched to libusb-1.0 and libftdi-1.0 and they
have seen significant performance boost. But OpenOCD has not
yet used the async feature of libftdi-1.0.

PS: libftdi-0.1x under Linux has some async support as well
based on usbfs. It is rather a hack though.
