ActionScript 2.0 is the second major release of the ActionScript object-oriented programming language from Macromedia, based on the ECMAScript 4 Netscape Proposal with class-based inheritance.[1]

Product history[edit | edit source]

Macromedia Flash Player 7 (MX 2004) introduced ActionScript 2 along with support for CSS styling. ActionScript 2 can cross compile to ActionScript 1.0 byte-code, so that it can run in Flash Player 6.

Macromedia Flash Player 8 further extended both ActionScript 1 and 2 by adding new class libraries with APIs for controlling bitmap data at run-time, file uploads and live filters for blur and dropshadow.
