WoW:3.3.5a

3.3.5a is the latest release of World of Warcraft: Wrath of the Lich King (in most locales).

Reverse engineering

Many attempts have been made throughout history to study the internals of this client. However, these usually aren't shared with the public.

A project of Thunderbrew, Binana, aims to provide machine-readable reverse-engineering information for the entire 3.3.5a binary in a single repository. By contributing to Binana, we can collaborate and build upon each other's work.

Compiler

For Windows, the client was known to be compiled using the Microsoft Visual C++ Compiler (VS2005, build 50727).

For the Mac OS X port, the XCode version of GCC was used.
