What is the difference between Flash 5

And macromedia Flash MX.
My friend has Flash 5, but I dont know which one is most advanced.
Thank you for your help.

Adobe took over Macromedia years ago. Flash five is the latest, and anything with ‘Macromedia’ on it and ‘MX’ is quite old now.

Flash 10 is the current version. Developing for flash 9 is still acceptable. Flash 5…is 11 years old.

Oops, sorry, I was thinking of Flash in CS5. Always get confused about that.
