Meridian 59: 5 Open Source Clones Compared
Meridian 59 Server 105 (v2.9.3, February 2016) and Meridian 59 German Server 112 (v3.0, September 2023) are two releases of the same 'Server 105' codebase — the older one's own README explicitly promises the newer, git-history-included 3.0 release that German Server 112 turned out to be. Meridian 59: New 3D client and developer tools (OgreClient) isn't a full game release at all; it's only a 3D client that connects to a compatible existing server's own game content, and its author doesn't distribute any binaries directly. The base 'Meridian 59' repository and 'Open Meridian' are separate, complete code releases (client, server, and tools) with their own player communities, distinct from the Server 105 lineage.
