Java Edition version history/Development versions

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.

Availability
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. The player is able to change to other snapshots through the profile editor.

Naming
There are several development builds of Classic versions of the game which were never released to the public. Some of them are now available through the launcher. In-game, the versions were labeled as their public release counterparts (e.g. 0.0.14a), but had distinct differences from the versions released to the public. Classic 0.24 is the only exception to this rule, as it was labeled simply "0.24" in-game, whereas the full release was labeled "0.24_SURVIVAL_TEST"

There are several builds of Indev 0.31 20091223-1 which were never released to the public. Most were still labeled "0.30" in-game.

The day before Beta 1.6 was released, Mojang created a Test Build version that was never released, but was nonetheless a development version for Beta 1.6. Between Beta 1.7.3 and Beta 1.8, 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 re-designated as release version 1.0.0, 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 YYwWWn. "YY" is the two-digit year, "w" simply stands for "week", "WW" is the two-digit week number within the year, and "n" 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, however, 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 pre-releases.

Pre-releases were originally named as version number Pre-release x, where x was either blank or a revision number; this format was used during development of Beta 1.8 (e.g., Beta 1.8 Pre-release 2). Pre-releases for 1.0.0 removed the hyphen in the word "Pre-release" (e.g., Beta 1.9 Prerelease 3). Release versions until 1.7.4 were released as full versions and incremented the minor version number for each pre-release (for example, 1.4 and 1.4.1 were both pre-releases for 1.4.2, and the pre-release for 1.4.7 is identical to the full release of 1.4.7). From 1.7.6 to 1.13.2, pre-releases had the format version number-prex, where x is the revision number (e.g., 1.12-pre2). 1.14 started naming pre-releases as version number Pre-Release x (where the word "release" may or may not be capitalized), where x is the revision number (e.g., 1.14.1 Pre-Release 2).

Release candidates were re-introduced with 1.16 Release Candidate 1. These are intended to be the last version before the full release, unless a major game-breaking bug is discovered. Release candidates are formatted as version number Release Candidate x, where x is a revision number.
