BNLS has been updated for Warcraft III and The Frozen Throne patch 1.20b. The version byte for both is still 0x14.
There were no major protocol changes in this patch; if you were using BNLS to acquire the latest version byte/version check values, then you should not have any problems logging in with the new version without any clientside changes.
