Starting in the period between Beta 1.7.3 and Beta 1.8, Mojang began to publicly release testing versions of full updates in order to get major feedback, especially for bug reporting. This enabled the official updates to be considerably more stable.

Mojang generally releases snapshots on Wednesday. The day had been Thursday, until the release of 14w26a on June 25, 2014, in the middle of development for 1.8.[1]

Snapshots & pre-releases


A statistic of released snapshots. Click into the image for more information.

These versions are publicly available, though they are not auto-installed by the launcher unless the Enable snapshots checkbox is ticked in the profile editor, and then it will only download the current version's development's set of snapshots and pre-releases. You are able to change to other snapshots through the profile editor.

For instructions on how to install a snapshot, read this tutorial.


Late in Beta development, Mojang began to issue pre-release versions, specifically for Beta 1.8 and what then was known as Beta 1.9. As Beta 1.9 came to be redesignated as release version 1.0, candidates subject to release were designated with the prefix "RC#".

The weekly snapshots for release 1.1 and onward are named by using the format YYwWWx. YY is the two-digit year, w simply stands for "week", WW is the two-digit week number within the year, and x is a unique letter identifier – starting with "a", then "b", and so on – for when there is more than one release per week. Currently the highest letter reached is e, a tie between 12w30e, 13w47e and 15w35e. The naming convention is broken by 13w12~. The update that has the most snapshots is release 1.9, with a total of 56 snapshots. The update that has the most pre-releases is release 1.13, with 10 prereleases (however, release 1.0 does surpass 1.13 if you count all of the Beta 1.9 prereleases and release candidates, including reuploaded versions).
