Imagine the pain at hundreds of files... so we made our own GitHub commit/PR diff viewer - here it's viewing a 50,000 line diff with 2000+ changed files 👀

@MPolley13 The wait is over!

@PaperPowered Waiting for 1.21.1 lol jk jk

We have decided to officially announce the end of life of Waterfall. Head over to the forums to find out about the Why's and What's: forums.papermc.io/threads/1088/

Hello! Stable 1.21 Paper and Velocity builds are now available! See the full update post regarding the inclusion of spark, default config changes, a few API breaks, and more forums.papermc.io/threads/1-21.1…

Nice tool! docs.papermc.io/misc/tools/ite…

Please see the following announcement to make sure your plugins will stay compatible with future versions of Paper: forums.papermc.io/threads/import…

@RijsberhpC We haven't tested any older versions, but in theory it could go back as far as 1.13

@PaperPowered Is this exploit also happening in older MC versions?

A crash-exploit that was fixed in Paper a few weeks ago is making the rounds now, please make sure to update to the lastest 1.20.4 builds from our website.

If you for some reason really cannot update now, here is a temporary solution to the problem in form of a plugin: hangar.papermc.io/kennytv/Exploi… There is a number of plugins claiming to fix this already, but they either don't properly catch the exploit or also impact normal users.

These changes are still some time away, but doing any required updates as soon as possible would be ideal. In the future, this means that two major, unnecessary barriers to using internals will be gone, since we recognize that sometimes you can't achieve *everything* with API.

❕If you are a plugin developer and are using vanilla internals in any your plugins, please test them on the following server jar to make sure they are compatible with future versions of Paper: github.com/PaperMC/testin… Also see #post-2955" target="_blank" rel="nofollow noopener">forums.papermc.io/threads/paper-… for more information.

Spottedleaf brought another experiment to Paper: A new Minecraft region file format that is both smaller and faster than the current format (more info on the images in Tweets below)🐳 github.com/PaperMC/Sector…

Experimental Paper 1.19.3 builds are now available on our website! ⚠️ Make sure to create backups of your server before upgrading, these builds may still have yet unknown issues. You cannot downgrade again after updating. ⚠️

1.19 #92 adds API to add custom chat completions, useful for adding stuff like emoji completions! #95 adds new collision APIs to check for in a world, as well as whether an entity would collide with boats, the worldborder, or any block at another location #ThisWeekInPaper
