Commands

• Added /setidletimeout <minutes until kick> to automatically kick idle players after a set length of time.
  • Multiplayer-only command, can be used only by server operators.

NBT format

• Added <structure>.dat files in data folder for storing structure data.
  • Contains files called "Village.dat" (villages), "Fortress.dat" (nether fortresses), "Temple.dat" (desert pyramids, jungle temples, and witch huts), "Stronghold.dat" (strongholds), "Mineshaft.dat" (mineshafts), and others.
• NBT structure consists of the individual parts of each structure, labeled "children", the chunk it originates in, a tag called BB, and an ID for what type of structure it is.
  • The children tags have information on each part of the structure and the type of part it is

Achievements

• Added the achievement "Diamonds to you!", which is obtained by throwing diamonds at another player.

Lighting

• The sky near the horizon now darkens when the player has blocks between them and the sky.
  • The greater the distance between the player and an area open to the sky, the darker the sky appears.

Maps

• Improved placing maps into item frames.

Zombies

• Reduced lag from the zombies.

Achievements

• Improved achievements.
• When a player earns an achievement, it is now announced in chat.
  • This can be disabled on servers in the server.properties.

"Super Secret Settings"

• The button now applies different experimental shaders.
• List of available shaders: antialias, deconverge, outline, art, desaturate, pencil, bits, flip, phosphor, blobs, fxaa, scan_pincushion, blobs2, green, sobel, blur, invert, wobble, color_convolve, NTSC.

Video settings

• Render distance is now a slider ranging from 2 to 16 chunks.
• The sky is now visible on short (4 chunks) render distance.
• The chunks can now render past 12 chunks.
• Max framerate is now a slider ranging from 10 to 250 fps, then unlimited.
• Added mipmapping, anisotropic filtering, and FSAA (as a shader).
• Mipmap levels setting is a slider ranging from off to 1 through 4.
• Anisotropic filtering can be disabled or set to 2, 4, 8 or 16.
• Post-processing (shaders) can be toggled.
  • They now display on the whole block.

Fog

• Re-adjusted fog distance to appear near the render distance limit, reverting changes made in 13w36a.
• Fog now covers 25% of the view distance, compared to 75% before 13w36a.

Distance effects

• Item frames now no longer simply follow the camera at extreme coordinates.
  • This is due to them being affected by an even more extreme bug as of this snapshot.

7 issues fixed

From released versions before 1.7.2

• MC-28625 – The horse armor equip sound does not play when replacing it with already equipped armor.
• MC-31065 – Villages were not generating (snapshot 13w37b).

From the 1.7.2 development versions

• MC-3973 – Players who mine redstone lamps with Silk Touch would get a lit redstone lamp in their inventory.
• MC-30483 – When the player sets their render distance too far it stays on normal.
• MC-30694 – Endermen stare sound still plays when the enemy mobs sound slider is at 0%.
• MC-30822 – Enchanted books with no metadata.
• MC-30858 – A player selector with only one matching player outputs as " and USERNAME .."

• 13w38a was previously removed from the launcher for some time but was added back in September 2018.
• As with 13w38b, this snapshot was released on the same day as 1.6.4.
