The main difference is a general simplification of the letters, reducing the number of strokes to generally not more than 4, which makes hand writing much more manageable. For instance, H which used to require a minimum of 7 strokes, now only requires 3.
Another change is the fact that the 26 original letters have been consolidated down to 24. This was done by combining "I/J" and "W/X."
I don't have a font for the Attack of the Clones version (yet). What you see here is an altered version of the "New Mando" (Mandalorian 2010) font by Erik Stormtrooper.
I did create a font for The Clone Wars version, which is freely available at https://AurekFonts.github.io/?font=MandoAF
