Java Edition Beta 1.9 Prerelease

Beta 1.9 Prerelease is the first of six pre-releases for 1.0.0.

Unofficially named the "Lost Update", Beta 1.9 never came. Instead, Mojang opted to delay the release of this update until MineCon 2011 and release it under the name "Minecraft 1.0.0". This decision was made after a few development versions tagged as Beta 1.9 were already sent out, so the name Beta 1.9 was kept for all of the development versions in the gap between Beta 1.8.1 and Minecraft 1.0.0, other than the Release Candidates.
