Back from vacation, we're now trying to finalize 1.13.1 and get it to you as soon as possible. We're pretty happy with where 1.13.1 stands now, and are aiming to get the full release out on Wednesday (22nd of August) unless some major bug pops up.
A full changelog for this pre-release can be found on Minecraft.net.
CHANGES IN 1.13-PRE2

- Bug fixes!
BUGS FIXED IN 1.13.1-PRE2
To get pre-releases, open your launcher and go to the "launch options" tab. Check the box saying "Enable snapshots" and save. To switch between the snapshot and normal version, you can find a new dropdown menu next to the "Play" button. Back up your world first or run the game on in a different folder (In the "launch options" page).
Please report any and all bugs you find in Minecraft to bugs.mojang.com.
Pre-releases can corrupt your world, please backup and/or run them in a different folder from your main worlds.
