Stanford was nice enough to releases a new FahCore_14 ver 1.23 today, as usual with no warning to the Faithful. If you have a firewall the download might get blocked requesting permission to download the new FahCore.
For the new Folders that haven't gone throught this before, the new FahCore should install itself automatically, you just have to make sure your firewall does not block it.
I received the new FahCore at ~ 15:10 hrs along with a new WU 5900. The new WU is worth 420 pts and seems to Fold at a rate somewhere between the

511pt and the 384pt WU's. It should be interesting to see what effect the new FahCore has on the older WU's ppd.
Don't forget to update you FahMon/FahSpy WU database so the new WU's will get recognized...
Update; The new Core/WU combo behavior seems to include;
Runs much cooler than previous WU's
Wide variation in CPU usage
Large swings in time per frame
According to Stanford this is all expected behavior...
