[Hakan Kuecuekyilmaz]

Dear Falcon fellows,

it is mid of April and our team decided to focus on recovery
related bug fixes for the next two months.

Since my last report of 2009-04-03 we fixed around 11 bugs.

The full test overview is located at:

For our external guests, I have a blog entry here. This time
I have an interview with Vladislav Vaintroub in the blog version
of our WFTO.
