OmniWeb is currently at version 4.1.1 (v424.6).
There are BIG plans for OmniWeb 5, but they are still far from complete. The most optimistic projected release date for a 5.0 built is "early 2003".
What kind of big plans? Well, Rick and Ken have said publicly that they are gutting the rendering engine and rewriting the bulk of it from scratch to fully support the modern web technologies. That includes full DOM, CSS, and XHTML support. Also, the new engine will be *vastly* faster at rendering pages than the current one because Omni will be trimming and rewriting the custom subclasses used in the page layout (currently each object is a full NSView and that accounts for a lot of overhead). OmniWeb 5 also rearranges how certain threads are handled, making the interface more responsive under certain conditions. In theory, OmniWeb 5 should easily blow Chimera out of the water unless the Chimera folk make an enormous effort to gut the cross-platform code from Mozilla (which I strongly doubt).
Unfortunately, I believe your license for OmniWeb 4 will not be valid for OmniWeb 5. Omni gives free 4.x and 4.x.x releases but not full integer releases. Though, it will still probably be free (with just the nag screen) and you can be happy that you supported the development of such a great browser.
It should be noted that Chimera has required only a tiny fraction of the work OmniWeb has. Remember, Chimera is basically just a pretty interface on top of the code from Mozilla/Gecko/Fizilla. All the "plumbing" was complete when folks started the Chimera project. The Omni Group, on the other hand, writes all of its code from scratch.
