that is everything we've seen up and untill, and including the beta release.
the engine version will only change with a major code overall, not just new features.
there will be 1 last update before Navi engine 2 is started.
here is a brief rundown of what will be included in each version:
Navi Engine 1
+Animations: blink, jackout, clock change
+Clock, navi image, time, battery, single background, date,DoW
+start basic framework for engine 2
+[TODO] temperature display, show battery level in an HP box.
Navi Engine 2
+Configuration page,
+Change speed of all animations
+ turn on/off and of the visual elements (even the navi! lol)
+change background
Navi Engine 3
+optimize the code for users to create there own PET's with their own navi's!
+Possible bundle some other navi's besides megaman
+release source code (upon completion)
engine 3 will probably take the longest, but v2 is still a few weeks away!
