Minecraft Beta 1.0.1 -

Warning: Do not use your main save file. The old world height (128 blocks) and lack of Anvil format will corrupt modern worlds.

Because Beta 1.0.1 was live for only a matter of hours before being superseded by Beta 1.1, very few players actually downloaded and preserved the specific .jar files for this version. For years, it was considered a "lost" piece of Minecraft history.

Every bug fixed in Beta 1.0.1 was a lesson learned in netcode optimization. Notch was forced to confront the realities of latency, packet loss, and server-client authority. The patch laid the groundwork for Beta 1.1 and the famous Beta 1.3 updates, which eventually introduced more sophisticated save formats and optimized chunk loading.

While Beta 1.0.1 may just look like a list of boring bug fixes on paper, it represents the agility, grit, and community-driven nature of Mojang during its golden indie years.

To make matters more confusing, Notch released on the same day (December 22, 2010), just four hours later. For years, it was considered a "lost" piece

If you look at the Minecraft launcher today, you will notice that Beta 1.0.1 is not readily available in the historical versions list. Why? Because it was replaced almost immediately.

A strange, unintended feature appeared in 1.0.1 that wasn't in 1.0: water became slightly more transparent when viewed from above. This wasn't in the patch notes, and Notch never acknowledged it. In Beta 1.0.2 (released two days later), it was reverted.

For video game historians and software archivists, Beta 1.0.1 holds a unique mystique. Because early Minecraft updates were pushed directly to a central server and overwritten locally on the player's machine, many short-lived hotfixes from the Alpha and Beta eras were lost to time. For years, Beta 1.0.1 was considered a "lost version" within the Omniarchive community—a dedicated group of digital archeologists tracking down every historical jar file of the game.
