So far, so good for me.  I performed a test flight from KIAH to KAUS with the v4.2 update.  I input a restriction of 140/3000 at BROMS, and it worked without a CTD.

Had no trouble picking up LOC and G/S on runway 17R at KAUS once I dialed in the correct settings on the radio stack.  ILS guided approach went flawlessly.  I was very pleased with the initial test flight on this one.

However, I did get a CTD once when I selected "End Flight" after pressing ESC after landing, but I would consider this a minor issue for now.  I will keep my eyes open for issues as I test it more extensively.  I may yet uncover other issues.
