.898 Is the latest 'stable' version which is linked from the front page, and on the forums there are various updated builds that are labeled unstable as they 'could' have potential problems.
I've had both .898 and .93 crash on me from time to time. Everything crashes now and then(I'm sure I've crashed every program i run regularly), just save often, and if you find something specific that causes Construct to crash report it on the tracker.
