User:JEC6789/Downgrading

In Minecraft, downgrading refers to reverting to an older version of the game.

$$, downgrading can generally be done through the Minecraft Launcher's backwards compatibility feature. If a version is not shown on the launcher, links to download the client and server may be available on its respective version page on this wiki.

$$, downgrading can be done by searching for and downloading unedited s online.

Users may need to downgrade as newer versions drop support for older hardware. For example, Java Edition 1.6.1 dropped support for systems using microprocessors, so anyone using them would have to downgrade to 1.5.2 to continue playing the game.

Issues
Since older versions of the game are not supported by Mojang, any issues associated with downgrading will not get fixed.

Bedrock Edition

 * If the player places down a block and then downgrades to a version where it doesn't exist, it will get replaced with an info_update2 block. Updating back to a version where it does exist will not change it back to its original form.
 * If the player gets an item in Survival mode and then downgrades to a version where it doesn't exist, it will permanently disappear from their inventory.
 * If any options are changed in v0.7.0 or later and the user downgrades to v0.6.1 or earlier, all the settings will get reset. This is due to a different method of setting storage being used instead of options.txt.
 * Downgrading to another version from any pre-0.7.0 version will also reset your settings. This is likely due to the settings being stored directly in the game itself instead of in the separate com.mojang folder.
 * Since downgrading doesn't delete the options.txt file, updating back to v0.7.0 or later will change your settings based on what's in it.
 * If you save a world while you're flying in v0.2.0 or later and then load in the world in v0.1.3 or earlier, the world gets corrupted and no longer loads in any chunks in any version.
 * If a world is loaded in v0.9.0 build 1 or later and is then loaded in v0.8.1 or earlier, its save gets corrupted and generates a new world with the same seed. This is due to later versions using a different level format that isn't compatible with earlier versions. Any blocks and items in the inventory with a valid ID are still saved.
 * Since the player's Y-level is also still saved, this can potentially result in terrain spawning inside the player and causing suffocation, especially if a flat world gets downgraded.
