Java Edition Beta 1.6/Development versions
This is a list of Java Edition Beta 1.6 development versions.
Beta 1.6 (preview)
A special pre-release version of Beta 1.6 was privately given to Hat Films for the creation of the official Beta 1.6 trailer.[1]
Beta 1.6 Test Build 3
Beta 1.6 Test Build 3 is a version used to test Java Edition Beta 1.6 the day before its release. It was never officially released to the public; however, both the client and the server are packed in an archive that can be found on the legacy update server.[2] This is the first and only known test build released in 2011.

World generation
- A line of 11 chests generates near the spawn point, containing all the blocks and items with unique IDs. These include blocks and items that are normally unobtainable, but exclude data value variants (such as colored wool or charcoal). The game always generates a line of 11 chests, but some of them are sometimes placed at Y=0, making the line on the surface seem incomplete. The content of the chests is the following:

Trivia
- Advanced OpenGL is enabled by default in this version. In Beta 1.6 Advanced OpenGL was removed temporarily until Beta 1.6.5 due to bugs.
- Advanced OpenGL crashes Minecraft on some computers.
- Picking up multiple stacks of items takes a few ticks to finish, unlike the final version where it only takes one.
- The fix for the crash when riding a vehicle or animal through a nether portal is done differently.
- Session requests are performed over HTTP instead of HTTPS.
- Session requests fail on any code other than HTTP 200, instead of only with HTTP 400.
- Connection to the server is closed differently; no thread is used in this build.
- GL state when rendering items is not properly reset, which may lead to graphical artifacts.
- Tall grass renders differently:

Validity
While modern versions of Minecraft are hosted on s3.amazonaws.com/Minecraft.Download, this version is hosted on s3.amazonaws.com/MinecraftDownload (without the period). At first it may seem that this site is not owned by Mojang Studios, but it can be verified as Mojang-owned in several ways:
- The legacy Minecraft launcher (from 2013) uses this site to update, which can be verified through a decompiler.
- Java Edition Classic was loaded from
s3.amazonaws.com/MinecraftDownload/classic/minecraft.jarwhen it could still be accessed on minecraft.net.[4]
