&amp;#039;&amp;#039;&amp;#039;12w21b&amp;#039;&amp;#039;&amp;#039; is the seventh [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.3.1]], released on May 25, 2012,&amp;lt;ref&amp;gt;{{mojangsnap|12w21b|May 25, 2012|Jeb}}&amp;lt;/ref&amp;gt; which updates the [[Minecraft:Creative inventory]] and fixes some of the bugs and crashes from the [[Minecraft:12w21a]] snapshot.&lt;br /&gt;
&lt;br /&gt;
== Changes ==&lt;br /&gt;
=== Blocks ===&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;[[File:Emerald Ore JE2 BE1.png|32px]] [[Minecraft:Emerald ore]]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
* Texture changed from [[File:Emerald Ore JE1.png|32px]].&lt;br /&gt;
&lt;br /&gt;
=== Gameplay ===&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;[[Minecraft:Chunk]]s&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
* Saving and loading chunks is slightly faster.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;[[Minecraft:Singleplayer]]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
* Removed [[Minecraft:server.jar]] dependency in singleplayer.&lt;br /&gt;
:* This was included in the official changelog for the previous snapshot, but not actually implemented until this one.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;[[Minecraft:Creative]]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
* New [[Minecraft:inventory]] screen in Creative mode.&lt;br /&gt;
** [[Minecraft:Block]]s and [[Minecraft:item]]s are sorted by category, each category in its own tab, the categories are: &amp;quot;Building Blocks&amp;quot;, &amp;quot;Decoration Blocks&amp;quot;, &amp;quot;Redstone&amp;quot;, &amp;quot;Transportation&amp;quot;, &amp;quot;Miscellaneous&amp;quot;, &amp;quot;Foodstuffs&amp;quot;, &amp;quot;Tools&amp;quot;, &amp;quot;Combat&amp;quot;, &amp;quot;Brewing&amp;quot;, and &amp;quot;Materials&amp;quot;.&lt;br /&gt;
** The inventory can be searched for specific items: just start typing while in the inventory screen. The search results are displayed in the &amp;quot;Search Items&amp;quot; tab.&lt;br /&gt;
** The player&amp;#039;s Survival mode inventory is accessible via a tab with the [[Minecraft:chest]] as its icon.&lt;br /&gt;
** Brewed [[Minecraft:potion]]s are not included in their own category.&lt;br /&gt;
** To close the new inventory window, the [[Minecraft:player]] must press &amp;lt;nowiki&amp;gt;&amp;#039;Esc&amp;#039; or &amp;#039;Escape&amp;#039;&amp;lt;/nowiki&amp;gt;. Using the default inventory key does not currently work.&lt;br /&gt;
** Added [[Minecraft:monster egg]] to Creative inventory.&amp;lt;/onlyinclude&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Trivia ==&lt;br /&gt;
* This version includes translation griefings.&amp;lt;ref&amp;gt;{{tweet|jeb_|206015255132905472|Seems another griefed translation passed through. Wonder if BBC is going to call me this time, too. If this continues, I&amp;#039;m gonna be famous!}}&amp;lt;/ref&amp;gt;{{info needed|clarify? the 12w04a page does this in its trivia section}}&lt;br /&gt;
