 <p>This is the first public test build in a while, so there is a lot of new stuff to take in.</p>
 
-<p>First up, a warning: Some new stuff is going down that might break on you.. Overview overhead figures aren't completely finished yet. I know about these and am working on them.
-You will likely have to Rebuild CPAP data to get this to behave properly.. If you have to do it more than once, somethings not right, and I need to know.</p>
-
-<p>Right clicky menu has tons of new stuff for you to play with... some of this you're hopefully going to love! :)</p>
-<p>New Graph Clone ability allows you to make a temporary copy of a graph, and operate it completely independently...

+<li>New Graph Clone ability allows you to make a temporary copy of a graph, and operate it completely independently...
 You can even take these graph clones with you to another day! They aren't saved though. they are gone when you close SleepyHead.</li>
-<p>Y-Axis menu allows for better control of Y-Axis scaling, all of this has been improved greatly... no more having to go into preferences
-to set minimum/maximum values (that SleepyHead wasn't honouring properly anyway). Now you can adjust these settings live for each graph!</p>
-<p>Line Cursor mode (F3 to toggles) is a very powerful new feature.. Play with it and see what it does. It's off by default because it takes a lot more CPU power to work.</p>
