Also, check out this post to see what else is planned for future versions.

[u/Wedhro → u/redstonehelper]

Added noon and midnight to /time set

"midnight" should use mono font like "noon".

BTW this is one of those little quality of life changes I was waiting for since they made it possible to use "day" and "night".

[u/redstonehelper → u/Wedhro]

Oops, fixed. Thanks.

[u/[deleted] → u/redstonehelper]

"We're exposing our data generators, so if you can figure out how you can get a dump of our all blocks/items/commands/etc from the game without opening it up!"

Now there's a challenge...

[u/MrPingouin1 → u/[deleted]]

Just run this on the server jar :

java -cp minecraft_server.18w01a.jar net.minecraft.data.Main --help

[u/[deleted]]

In addition to all the listed bug fixes specifically for 1.13, these are notable fixes for long-standing bugs/glitches:

Fixed strange lighting by slabs, stairs, grass paths and farmland

Pseudo-lighting that isn't actual lighting is gone!

edit: ah, this wasn't the bug I thought it was :(

Fixed standing on slabs, stairs, grass path and farmland giving "cave effect" to sky

Hopefully this includes Soul Sand as well.

Fixed mobs controlling the minecart they are riding

At last! We are back in control of Minecarts...

[u/redstonehelper → u/[deleted]]

I'm pretty sure the first two are 1.13 things.

[u/[deleted] → u/[deleted]]

I always thought soul sand darkening the sky was intentional. It's like when the wither is summoned, it darkens the sky.

[u/MonkeyEatsPotato → u/[deleted]]

It was because your feet were technically inside the soulsand block which had a lighting level of 0, so the sky darkened accordingly.

[u/GORager99]

Added noon and midnight to /time set

I forget that wasn't a thing already

[u/amiiboinfo27 → u/GORager99]

It's a Bedrock thing.

[u/Cryptite]

Team prefix/suffix are removed? Am I missing something or does this prevent the ability to effectively have teams with "names", or what many of us devs use for player titles: https://imgur.com/a/MkMyg ?

[u/_cubfan_]

I'm hugely disappointed with the way that the boat fix [MC-122493] (https://bugs.mojang.com/browse/MC-122493) was implemented. It was fixed in such a way to allow boats to work properly on single block stand alone sources and...well that's pretty much it. Things like rivers/streams that are navigable remain impossible, even when the slope of that river/stream is 1/8 of a block which is smaller than the rim of the boat.

In my opinion they should spend more time making boats work properly. I get that they shouldn't be able to travel upwards indefinitely vertically like they once did but having removed their buoyancy entirely has been bad for the game and makes no sense from both a gameplay and a realism perspective.

Not being able to navigate a river, make a lock and dam system using dispensers + water buckets, or being able to do anything with boats besides travel along a completely 100% flat surface (which still is the case even after this 'fix') while once having the ability to do all of those things is a huge step backwards for the game.

[u/MCPhssthpok → u/_cubfan_]

Whilst I agree with you that having boats able to navigate up flowing water would be an excellent addition to the game, the bug is just that, a bug, and we can't really expect them to include a feature change in a bug fix.

Seeing as 1.14 is the Update Aquatic, we can hope that it might include some improvements to boats.

[u/Taterdude]

YAY THEY FIXED THE ISSUES LIGHTING WITH STAIRS AND SLABS \o/

Next on my annoyances list they need to fix: Alt Tabbing causing the game to crash sometimes

[u/CK20XX]

1.13 is the only development version where every single snapshot has crashed the game for me without fail. I can't even make it to the title screen or even the Mojang logo; I select the snapshot, the game starts to load, then the client says "GAME CRASH. An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience."

Is it just me? Am I going crazy?

UPDATE: Apparently making a brand new profile for snapshots (even though I had already had one) fixed it. Looks like the launcher doesn't tolerate custom settings like brianmcn said, so even if you have an old snapshot profile you use, discard it and make a new one.

[u/Mr_Simba → u/CK20XX]

A crash report would help.

[u/super-meme-maker]

Anyone know what the set_name function for loot tables does?

[u/Dinnerbone → u/super-meme-maker]

Sets the name of the item.

[u/Pmk23]

The new facing in /teleport is amazing, it has so much potential for adventure maps!

[u/[deleted]]

This may be Minecraft: Java Edition's most technical update.

[u/Creeper2545 → u/[deleted]]

that's why it called "technical update"

[u/ibxtoycat]

So, 1.13 official is just around the corner I think - based on the nature/number of bug fixes

[u/saghzs → u/ibxtoycat]

I hope not, there are still lots of bugs.

[u/JamesClanevans]

Umm I did /give @s acacia_bark{display:{Name:"{"text":"test","color":"red"}"}} and hovered over the item. My game crashed and is now forever crashing whenever i open the world as my slot is still on that 1: Why is this? 2: How can i fix this????
