WFTO – start of April report

it is start of April and we were very busy fixing bugs. Kevin, Jim,
and Olav implemented our new CycleManager, which closed a lot of bugs.

Olav implemented our new TransactionState object, which we also
account for closing quite a few bugs.

Since my last report from 2009-03-20 we fixed around 17 Falcon related bugs. Compared to our last WFTO from 2009-03-20 we have 1 new test.

The development of our failed/passed tests ratio over time looks like:

• 1.20% – 3/249 (this report)
