Latest version

Here you can download either the modern Allegro 5 library, or the classical Allegro 4 library. Allegro 5 is not backwards compatible with Allegro 4.

Instructions on how to build Allegro for each of the supported platforms are included in the source packages, either in the README files, or in the docs/build subdirectory.

Since version 3.12, Allegro has adopted this versioning scheme: The first number indicates a major version; differences here usually mean that a lot of things have changed. The second number indicates if the release is stable (even number) or unstable (odd number). Finally the third number marks smaller differences between releases. A fourth number is used if we need to fix a minor mistake found in a previous release.
