There is no similar table for Community versions but it is generally safe to just use the Enterprise supported platforms as a reference because the 5.0 Enteprise version is just a fork/branch of the 5.0 Community one.
Not exactly... All Community 5.0 versions should be considered like Enterprise 5.0. 5.0.1 and other Enterprise versions do are not reflected in any Community version. You need to understand the release cycle of Alfresco for this - Community 5.0.a, 5.0.b etc. are all released before Enterprise 5.0, and when Alfresco Enterprise is released there will generally be no more Community Release afterwards unless there are significant security issues.
