Minecraft Alpha 1.0 16 02 -

For those who weren't digging through forums in 2010, this patch was a quiet one. No huge features. No hype. Just:

(The "Structure" Update)

Release Date: November 3rd, 2010 (Recovered Build) Client Hash: a10e6f...02 minecraft alpha 1.0 16 02

| Bug | Description | Resolution | |------|-------------|-------------| | Memory leak | World ticking caused RAM usage to climb indefinitely | Fixed in _02 | | Redstone torch burnout | Torches permanently deactivated under certain circuits | Partial fix | | Minecart collision crash | Two minecarts colliding at high speed crashed the server | Fixed | | Spawn rate anomaly | Hostile mobs spawned too rarely at night | Adjusted |

Then came Alpha 1.0.16_02 on August 13, 2010.

While it fixed the memory leak, it introduced a bizarre new quirk: Water and lava flow logic reverted to a single-threaded tick. In practical terms, this meant that if a server had more than 4 players, flowing water would freeze visually. You could swim through a river that looked like a static blue carpet. This "water lag" became a trademark of late-Alpha SMP, and many server admins refused to update past _02 because later versions had worse combat lag.
