15w45a is the thirty-ninth snapshot for Java Edition 1.9, released on November 5, 2015.^[1] The development team's aim had been to have the 1.9 release feature-complete by the end of October 2015, followed by a period of bug-fixing,^[2] and this snapshot was the first snapshot during that planned time period of bug-fixing.

Realms

• Added a "Realms Notifications" toggle to the options menu.

Lily pads

• Collision box was raised from ¹⁄₄ of a pixel to 1 pixel in height.

Maps

• Are crafted at a zoom level of 1:1, as was the case before 15w34a.
  • Can no longer be zoomed in.
• This reverts maps to 1.8 behavior.

Shields

• Placing a pattern on a shield now consumes the banner.

Elder guardians

• Rare drops now only provide fish, as they had in 1.8 versions, eliminating fishing treasure and fishing junk that had been seen in snapshots.

Shulker

• Added sounds for shulkers getting damaged.

Boats

• The dark oak boat can now be crafted.

General

• Tab-completed coordinate arguments now become tildes if no block is in focus.

NBT format

• The Linger byte tag on ThrownPotion entities has been removed.
  • Instead, the potion lingers if the stored item has an ID of minecraft:lingering_potion.
  • The following command creates a ThrownPotion lingering potion: /summon ThrownPotion ~ ~5 ~ {Potion:{id:"minecraft:lingering_potion",tag:{Potion:"minecraft:swiftness"}}}.
• The ThrownPotion renders as its stored item, no matter the item.
  • For instance, if the stored item has an ID of minecraft:diamond_sword, the potion appears as a diamond sword while being thrown.

Achievements

• Overpowered is changed from "Build a Notch Apple" to "Eat a Notch Apple".

Jumping

• Jump height increased from 1 ³⁄₁₆ blocks to 1 ⁴⁄₁₆ blocks.

Optimizations

• Tweaks to pathfinding and monster AI.
• Some performance optimizations.
