Viewing Algernon releases

Since there are two versions of Algernon, v3 for Protege 1.9 and v4 for Protege 2.0, there are usually two releases at the same time. However, SourceForge only shows the last release by default. To view all of them, click on the "View all files released" link at the beginning of the paragraph of text above the list of released files.
