Alpha v1.0.15,[1] along with server 0.1.0, is a version of Java Edition that introduced survival multiplayer servers.

The corresponding blog post is falsely labeled as "Minecraft Alpha v1.0.14", which is a duplicate of a previous version released four days earlier, on July 30.[2] The date of the jar and the timestamp of the post clearly show that it is Alpha v1.0.15 instead.

The server version was not released at the same time,[3] but instead was released one day later, on August 4, 2010.[4]
