'''21w20a''' is the twenty-second and final [[snapshot]] for [[Java Edition 1.17]], released on May 19, 2021,<ref>{{snap|21w20a|May 19, 2021}}</ref> which makes tweaks and fixes bugs, most of which relate to [[axolotl]] behavior and world generation issues.
|
|
|
|
== Additions ==
|
|
=== General ===
|
|
; [[NBT format]]
|
|
* Added <code>HasVisualFire</code> tag.
|
|
** Entities with this tag visually appear on fire, even if they are not actually on fire.
|
|
|
|
; [[Tag]]s
|
|
* Added the <code>features_cannot_replace</code> block tag.
|
|
** Contains [[bedrock]], [[Monster Spawner|spawners]], [[chest]]s, and [[end portal frame]]s.
|
|
|
|
== Changes ==
|
|
=== Blocks ===
|
|
; [[Glow lichen]]
|
|
* Now drops the correct amount of glow lichen if there's multiple in one block space.
|
|
|
|
; [[Rooted dirt]]
|
|
* Tilling rooted dirt with a hoe now converts it into dirt, and pops out [[hanging roots]], to match the behavior {{in|BE}}.<ref>{{bug|MC-220128}}</ref>
|
|
|
|
; [[Structure block]]
|
|
* All invisible blocks are now displayed as small cubes by save mode structure blocks; previously barriers and light blocks would not display at all.<ref>{{bug|MC-102220}}</ref><ref>{{bug|MC-221833}}</ref>
|
|
** Variants of air still all appear identical and are not distinguished.<ref>{{bug|MC-221834}}</ref>

=== Items ===
|
|
; [[Big dripleaf]]
|
|
* Tweaked the inventory model.
|
|
|
|
; [[Light block]]
|
|
* Changed the textures of inventory icons to prevent overlap with the stack number.
|
|
|
|
=== Mobs ===
|
|
; [[Axolotl]]
|
|
* Now only play dead when in water.
|
|
* Can no longer be fed tropical fish, only buckets of tropical fish, as axolotls in real life eat live fish. This also brings it to parity with Bedrock Edition.<ref>{{bug|MCPE-123573|||Works As Intended}}</ref>
|
|
* When fed with a bucket of tropical fish, it returns a water bucket instead of a bucket.
|
|
|
|
; [[Llama]]
|
|
* No longer spit at players on [[Peaceful]] difficulty.
|
|
|
|
=== World generation ===
|
|

|
* Fixed a precision loss issue with <code>minecraft:location_check</code>.<ref>{{bug|MC-205680}}</ref>
|
|
|
|
; [[Narrator]]
|
|
* GUI narration now includes position and usage of hovered or focused element.
|
|
|
|
; [[Tag]]s
|
|
* Added the <code>cave_vines_plant</code> block to the <code>bee_growables</code> block tag.
|
|
** The <code>cave_vines</code> block was already in this tag.
|
|
* Removed the tropical fish item from the <code>axolotl_tempt_items</code> item tag.
|
|
|
|
; Text
|
|
* Changed the strings "Chat disabled by launcher option, cannot send message" and "Chat not allowed by account settings, cannot send message" to "Chat disabled by launcher option. Cannot send message" and "Chat not allowed by account settings. Cannot send message", respectively.
|
|
|
|
; Protocol
|
|
* While connecting to a server, the client sends a handshake packet with "hostname" and "port" field directly padded with address given in address text field directly, instead of converting them to the real hostname and port.
