Issue: Minecraft crashing when entering main menu.
Try disabling Discord game overlay, or uninstall Discord. Then check out the My game doesn't respond or crashes upon launching! / My game is performing very poorly. section for more advice.
Issue: Old launchers can't play 1.13 anymore.
This is by design. Please use the latest launcher from minecraft.net/download.
Issue: Random Java crashes when running Minecraft client / server.
Make sure you're using Java 8 update 51 or greater. For the client, you should use the bundled version of Java; see the I'm getting an "Unable to locate the Java runtime" error when trying to run Minecraft. How do I fix this? section to find out how.
For servers, you should uninstall all earlier versions of Java, then reinstall the latest version of Java 8 from here.
Check out the My game doesn't respond or crashes upon launching! / My game is performing very poorly. section to see if it's definitely 1.13 or it's just you.

What is The Update Aquatic?
The Update Aquatic the latest update to Minecraft, and the first to be released across multiple Editions (Java, Windows 10, Xbox One, Switch, PS4) almost at the same time. There are new mobs, new items, new blocks, new structures, new biomes, new game mechanics, and lots of water. See here for a taster from Mojang. The complete 1.13 changelog is on the Minecraft website, as well as the Minecraft Wiki.
Other Editions have already seen releases for some of the Update Aquatic content, with more to follow. The aspiration is to eventually release it on all extant Editions of Minecraft.
So what is the biggest change?
As outlined by Mojang, the original plan was to have two separate releases, 1.13 "Technically Updated" and 1.14 "The Update Aquatic". The technical update was required to make it possible to add the new blocks and develop the game's mechanics for The Update Aquatic. For reasons these two were merged into a single version 1.13 combining them both.
The world save format has changed; worlds older than 1.13 cannot be opened with versions from 1.13 or later without permanently and irreversibly upgrading them to the new format, making it impossible to open them in earlier versions
This update is all about Ocean content. The new Biomes, underwater plants, Fish mobs and Dolphins, structures, will all generate only in new chunks.
How stable is the update?
As with all releases, some showstopper bugs may pop up after the game's release. If you need your game to be stable, it is recommended that you don't upgrade straight away. Instead, wait for a week or two and see if any players report game-breaking bugs, and give time for Mojang to fix them. See How can I stay on 1.12? for more information.
Alternatively, you can backup your worlds by making a copy of your saves folder before upgrading to 1.13, in case anything goes wrong.
What happens when I update my world? Will new ocean content generate in my old world?
Back up your saves. When you first open the world save in 1.13, it will be converted to the new save format and it will over-write the original save.
New content will only appear in newly generated chunks (mainly in Ocean/River Biomes), and will not alter existing chunks (with some exceptions: see below).
How can I delete/reset chunks in my world so they will regenerate in 1.13?
There are several techniques, some more involved than others. Back up your saves first. All of these methods require you to edit the world save before using 1.13.
When will the PS4 and other Legacy Console Editions get this update?
On May 3rd 2018, Mojang officially announced that most Legacy Console editions will be getting the Update Aquatic, but with the exception of PS4 they will receive no further feature updates after this release. All other Legacy Console Editions will cease development.
Work on Update Aquatic for Console Editions is progressing, but it won't be released until after all parts of the update have been released on the Bedrock version.
We don't have a date for when that will be, but we will let you know when it goes in to test.
Where is the Super Duper Graphics Pack DLC?
There's no connection between the Update Aquatic and the Super Duper Graphics Pack. There's no release date yet.
What has happened to the Customized World option? Why can't I migrate my Customized world?
Worlds originally generated using the "Customized World" options can't be opened in 1.13. You can edit the world save level.dat using NBTExplorer to remove the custom settings (change generatorName variable to default, and generatorVersion variable to 1). If loaded in 1.13 you will have the option to use the Optimize World feature to make a world created with the customized option playable in 1.13, but it will use the standard generation.
Why have my commands stopped working? What is the new command syntax?
Many commands have changed syntax, and may have new or changed arguments. Here's an early draft of some of the changes, the Official Wiki page has details of the changes made to commands.
Downloading and Running The Game
What are the minimum system requirements for Minecraft 1.13?
There are no hardware requirement changes for 1.13. If your computer meets the requirement for Minecraft now, it will be able to play 1.13.
However, as 1.13 brings updates to the underlying graphics library, older devices that do not meet the minimum requirements may no longer be able to play Minecraft. These devices are usually over 5 years old and are not built for modern games. In this case, you'll need a new GPU (if you're on a desktop) or a new computer (if you're on a laptop).
What's the minimum Java version required for 1.13?
Due to bugs in earlier versions of Java 8, Mojang recommends using the bundled version of Java (1.8.0_51) to ensure maximum compatibility. See this FAQ for instructions to use the bundled version of Java.
Java 9 and later versions are not officially supported at the moment. OpenJDK is also not officially supported - please use Oracle Java to play Minecraft.

How can I update my graphics drivers?
If you need help with updating graphics drivers, this page will guide you through the process. It also tells you how you can get technical support if you are unsure how to update your graphic drivers.
I'm getting an "Unable to locate the Java runtime" error when trying to run Minecraft. How do I fix this?
If you are getting "Unable to locate the Java runtime" errors when launching the game, head to Launch Options -> turn on Advanced Settings -> click on the profile you intend to use (usually Latest release). The Java executable options should be set to Off (grey). If not, turn it off, Save and restart the launcher.
Why can't I download the new server .jar?
The server .jar download site has changed, but the Launcher hasn't yet been updated. You can download the 1.13 server .jar here.
Why can't I download the new update?
Please see this article for ideas. Additionally, check the incompatible software list below to ensure you don't have any incompatible software installed.
What software might interfere with installing / updating or running Minecraft?
This page, maintained by #minecrafthelp, has tons of information on what software may be interfering with Minecraft.
One particular offender is ByteFence. If you are seeing an error message like this, it's most likely caused by ByteFence. It should be uninstalled from your system.

Additionally, on some systems or configurations Discord can cause problems. Make sure to disable the Discord in-game overlay. If you use Discord and are experiencing issues and disabling the overlay makes no change, completely close Discord while running Minecraft.
Why does Minecraft "crash" when I switch versions? How do I create a separate folder for new profiles in the Launcher?
If you are getting problems when switching between versions, it usually means that a shared config file is not compatible between versions. To get around that, create each version with a private profile in the Launcher.
How can I stay on 1.12?
You can do that by creating a new launcher profile. Head to Launch Options, click on Add new, give your configuration a name (e.g. 1.12), from the Versiondropdown select release 1.12.2 (do NOT select "Latest Release" as this will upgrade you to 1.13), then click Save.
To launch 1.12, click on the News tab, and the Play button will now have a dropdown button for you to select your profile. Select your new profile, then click "PLAY".
What is the Optimize World option?
Minecraft 1.13 introduced a new world file format. By default, this happens as players visit already-generated chunks; the game will update the world to the newest format on-the-fly. However, the Optimize World option forces the game to upgrade the world in one go, increasing performance in-game.
The game will normally prompt you to backup and optimize your world when loading a pre-1.13 world. However if you want to do this yourself, on the world selection screen you can select the world and hit the Edit button. From there you should select the Backup World option, then the Optimize world option.
When you optimize a world, the game client will create a backup for you and then go through the optimization process. This process will take different amounts of time based on world size and the computer itself.
For servers, you can pass in the --forceUpgrade argument when launching the server to force it to optimize the world (e.g. minecraft_server.jar --forceUpgrade). It is highly recommended that you manually make a copy/backup of your servers world folder before starting that server up in 1.13 if you have not done so already.
I'm still having trouble running Minecraft. What can I do?
You should open a new thread in this forum. You could also try asking the volunteers in the #minecrafthelp IRC channel for help and advice. Please be patient, they are likely to be very busy.
When will Minecraft Realms update to 1.13? How can I delay updating Realms until I'm ready?
The Realms server version will not update until the owner of the Realm updates and visits the server. At that point the world save will convert. There should still be a 1.12 profile in the owner's Launcher, so they can switch to that and download the Realm save first if required.
I'm receiving a message telling me to get parental consent before I can play Realms? What should I do?
Because of recent changes in EU data protection laws, all minors must obtain parental consent before they can access Realms. See this FAQ for more information
