Texture Update

"WHAT IS JAPPA DOING TO MY MINECRAFT? Changing the textures! Except for a few, like the Creeper. Across all versions? YEP, both on Java and Bedrock. You cannot escape my sweet, sweet textures. When? Soon! In the Beta Resource Pack, where all my beloved pixels live."

- Jasper "JAPPA" Boerstra

The Texture Update is an update released in Java Edition 1.14, Bedrock Edition 1.10.0, and PlayStation 4 Edition 1.90 (with further amendments in Bedrock Edition 1.17.10, as well as minor revisions in subsequent major updates for textures which were left behind). The update changes most of the textures in the game, except for a few iconic textures like the creeper. The textures were developed primarily by JAPPA (Jasper Boerstra). The original textures (with the exception of leather horse armor) are available as a resource pack/texture pack built in-game or as a separate download (named "Programmer Art" $$, and "Classic Textures" $$).

Preview textures
Some unreleased textures Jappa made when developing the final ones for the update.

Missed textures
While the majority of textures were updated to conform to the new art style, the following were not.

Textures which weren't updated

 * The nether wart, blaze rod, and blaze powder items still use their old texture.
 * Although chests, trapped chests and Christmas chests had their png files changed (file sizes too), they still use their old textures/pixels rather than updated ones.
 * The default player skins, "Steve" and "Alex", have not been updated in Minecraft: Java Edition unlike Bedrock Edition, creating a mismatch between the "Steve" texture and the zombie texture, which are supposed to be related.
 * Smooth stone slab had its file size and name changed, from stone slab, but it still uses the old texture/pixels.

Inconsistencies

 * The cactus bottom texture still uses the color scheme of the old cactus side texture.

Textures still using pre-Texture Update elements

 * The top texture of the observer is still largely based on the old "polished cobblestone" texture, rather than its updated version. This is apparently completely intentional.
 * The top texture of the ender chest is still largely based on the old "cobblestone" texture, rather than its updated version. Mojang have decided not to fix this.
 * The bedrock texture in natural end crystals has not been updated at all.
 * The inventory and toast GUIs still use the old Knowledge Book texture, rather than its updated version.
 * The Tutorial hints still uses the old oak planks texture, rather than its updated version.
 * Spectator icons, such as the 'exit menu' and 'teleport to player' are still based on the old barrier and eye of ender textures.
 * The pack.png for the default resource pack still uses the old grass and cobblestone textures, rather than their updated version.
 * The favicon for the game window uses the old crafting table texture, rather than the new one.
 * Dyed versions of terracotta have not been updated, although their undyed version has.
 * The Player Head still uses the old Steve texture in Minecraft Bedrock Edition despite the skin being updated in that version.

Slots and outlines

 * The empty armor slot textures in the Inventory still use the old textures, rather than their updated versions.
 * The icons on Statistics still use old item textures, rather than their updated versions.

Unsorted

 * The hand texture of the Drowned uses an old Zombie hand texture rather than the new one. This also affects Zombie Villagers, Illagers and Vexes, which is confirmed to be intended.
 * The options background still uses the old Dirt texture, rather than its updated version. This is probably not a Texture Update issue, as the dirt texture was last changed in 1.0.0.
 * Podzol still uses its old side texture rather than an updated one, even though its top texture is updated.
 * While normal pumpkin stem and attached melon stem use updated textures, attached pumpkin stem and normal melon stem still use the old ones.
 * Grass Blocks still use their old top texture rather than updated one, even though their new top texture has appeared in Texture Update Betapack V1 & V2.

Trivia

 * On April 1, 2018, the Texture Update was "released" on as an April Fools' joke. DOS-styled 8-bit default version of textures, with reductions in detail, were released for Java Edition, available in versions of 1.12.x and 1.13 snapshots from 17w43a to 18w11a, with the thread claiming that all editions of Minecraft would eventually get the textures.
 * The textures were reverted to the way they were before on April 2, 2018. These textures cannot be re-activated by setting the device's date to April 1, 2018.
 * These textures only replaced the default textures, so using a Resource Pack would hide the textures the resource pack would change.
 * The Texture Update Beta Pack gallery on the Minecraft Marketplace in Bedrock Edition uses screenshots from the Java Edition.
 * In a now deleted Tweet, JAPPA announced on November 10, 2017 that the new textures would be available on "all versions" of Minecraft. However, the update has only been released on the Java Edition, Bedrock Edition, and PlayStation 4 Edition. The Xbox 360 Edition, Xbox One Edition, PlayStation 3 Edition, PlayStation Vita Edition, Wii U Edition, Nintendo Switch Edition, and New Nintendo 3DS Edition still have not received this update.
 * The "polished cobblestone" on the piston prior to the texture update used to match the furnace top texture. After the texture update, they no longer share the same design.
