The latest version 1.11-8 was released September 7, 2011.
This library is significantly faster than the default regex parsing. I haven't got a clue what version we currently use but the license states 2005 so I'm guessing its been a long time since it was upgraded.
I'll get a patch together and for completeness run independent test to compare results pre and post upgrade. It would be nice to see > marginal improvements :0)
