By using my superior code breaking skills and complex multi-million dollar software, I think I have been able to nail down a time as to when Beta 5 will be out. I have posted the analysis below.
"There are a couple of major items (like TIR no longer working) that still need to be fixed before this Beta can be released, but as soon as they are fixed and internally tested, this Beta should be released shortly after.

As you can see, the complex algorithm has identified key letters in the quote above. The results of the 12 hour computations conclude that:
Tuesday, One Feb is when it will be released.
