It took longer than I thought. But we are finally there.

I am very happy that the wine dead loop bug is nailed
down and the looping while deleting bugs are stopped.

Thanks Luc for a lot of hard work there.

I hope this is the last RC for this release.

Let's ship this release out. The work for the next release
is already start to piling up.

Thanks every one that contribute to this RC5.

Again, please give it a good test.  Report back
any issue you might have.

Chris
