Version Differences

This article lists all parkour-related changes in newer versions of Minecraft (1.9+), including bugs and bugfixes.

For the full changelogs, see this article (Minecraft Wiki).

Changes are grouped into 3 categories:

• Movement: Changes or additions to movement mechanics.
• Blocks: New blocks, or changes in current blocks' properties.
• Other: Changes that should be mentioned, but that do not affect standard parkour.

1.9 (Combat Update)

Category	Changes
Movement	Jump height increased (from 1.249 to 1.252). Momentum threshold has been lowered (from 0.005 to 0.003). This is the reason why jump height is different, as well as taps. Sneaking now lowers the player's height (from 1.8m to 1.65m).
Blocks	Added End rods - 0.25×1×0.25 bounding box, can be placed in all directions. Added Chorus plants: Default: centered 0.625×0.625×0.625 bounding box (generally the same height as an end portal frame). Connects to adjacent chorus plants and flowers. Also connects to any ground below it. Chorus flowers have a simple 1×1×1 bounding box. Added Shulkers (technically entities) - 1×1×1 bounding box, but can rise by 0.20609b. Added Grasspath: 1×0.9375×1 bounding box Ladders are now 1 pixel wider (from 0.125b to 0.1875b) The bounding box of pane blocks have changed: The neutral variant is no longer a cross, now it's just a 2 by 2 pixels pole. The internal segments are 1 pixel longer. Lilypads are now 0.09375b tall (1.5 pixels) and 0.875b wide (reduced by 1 pixel on all sides) Boats (technically entities) are now 0.5625b tall (instead of 0.6b). Bugfix: Piston heads now match their model: The arms now have the correct width (0.25b). The arm's length is extended by 0.25b, making piston heads the only block that can protrude horizontally onto adjacent blocks. The west-facing extension is no longer bugged. Bugfix: Chests and Anvils now have a fixed bounding box. Bounding Box Manipulation is no longer possible. Bug: large Cocoa has the same bounding box as medium Cocoa. Fixed in 1.11. Bug: Panes and Bars connect to barrier blocks.
Other	Added Elytras. Added Levitation effect. Entities now push the player when colliding. Falling on a hay bale absorbs most of the fall damage.

1.10 (Frostburn Update)

Category	Changes
Movement	Added "Auto-jump" option in the Controls tab. When toggled on, it automatically makes the player jump. Auto-jump does not activate while sneaking. Auto-jump activates Notable uses include: 100% strat for hh 1+1 jumps, easy way for grinding on stairs aka "slab-boosting".
Blocks	Added Magma block, which damages the player when they are standing on it, unless they are sneaking. 1.10.1: Farmland is now 0.9375b tall (15px), instead of 1b.
Other	New Debug shortcut: F3+G shows chunk borders.

1.11 (Exploration Update)

Category	Changes
Movement	Sneaking now prevents falling more than 0.6b (previously 1b)
Blocks	Added Shulker Box - 1×1×1 bounding box, can extend by 0.5b when opened with right click. The extension increases and decreases by increments of 0.05b every tick. The shulker box can only be opened if it doesn't end up intersecting with another bounding box. Interestingly, the opening starts with a surplus of 0.01b, which means the player is actually pushed 0.51b. At the end of the opening animation, the extension's length is brought back to 0.5b. Bugfix: Large cocoa now has the correct bounding box. Bug: In 1.11.1 only, walls are only 1b high (0.875b in some cases). Fixed in 1.11.2.
Other

1.12 (World of Color Update)

Category	Changes
Movement
Blocks	Beds now have bouncing properties: Only converts 66% of the player's downward speed, unlike slime blocks which are 100%. Fall damage is reduced, but not completely negated unlike slime blocks. Walls, Fences, and Panes/Bars now connect to the backside of stair blocks. Bugfix: Walls and Fences no longer connect to perpendicular Fence Gates. Bugfix: Panes and Bars no longer connect to Barrier blocks.
Other

1.13 (Update Aquatic)

Category	Changes
Movement	Water physics were changed quite a lot: When simply walking, the player doesn't drop down as fast. Sneaking makes the player dive downward. Sprinting in water now puts the player in a swimming state, which makes them swim faster, and sets their height at 0.6. The speed and "area of effect" of flowing water now depends on its level. The player can jump out of water if it's low enough.
Blocks	Added Blue Ice, with a slipperiness of 0.989 (compared to 0.98 for regular Ice). Added bubble columns: Soulsand sets all consecutive water source blocks above it to upward bubble columns, which push the player up. A Magma block sets all consecutive water source blocks above it to whirlpool bubble columns, which drag the player down. Added Conduits, which have a centered 0.375×0.375×0.375 bounding box. Added Sea Pickles, which have 4 variants (depending on the number placed): Tier 1: 0.25×0.375×25 Tier 2: 0.625×0.375×625 Tier 3: 0.75×0.375×0.75 Tier 4: 0.75×0.4375×0.75 Added Turtle Eggs, which have 4 variants (depending on the number placed): Tier 1 has an uncentered bounding box of 0.5625×0.4375×0.5625 Tiers 2,3, and 4 have a centered bounding box of 0.875×0.4375×0.875 Some blocks can now be waterlogged. Anvils have a new model and bounding box: The base is 0.75×0.75, and its floor is 0.25b high. The top is 1×0.625, and its ceiling is 0.375b low. Wall blocks have a more accurate bounding box. The sides now match those of their visual model. The height remains at 1.5b. filled End Portal Frames have a more accurate bounding box. The eye now has a width of 0.5×0.5 (instead of 0.375×0.375) Cauldrons have a more accurate bounding box. The inner floor is now 0.25b high (instead of 0.3125) Hoppers have a more accurate bounding box. The inner floor is now 0.6875b high (instead of 0.625) The underside of the hopper is now accurately represented; Brewing Stand have a more accurate bounding box. The base is now 0.875×0.875 (instead of 1×1) Bug: exiting water at Y=256 sets the player in a state where they can jump higher.
Other	Added Tridents. Added Slow Falling effect - makes the player fall a lot slower. Added Dolphin's grace effect - increases the player's swimming speed. Added Debug stick - used for modifying a block's state. New Debug shortcut: F3+C copies the player's current coordinates. The Debug screen now shows info about the targeted fluid, on top of the targeted block.

1.14 (Village & Pillage)

Category	Changes
Movement	X/Z collisions changed, the first direction processed now depends on the player's velocity. If $V_{X}>V_{Z}$, the collision order is Y→X→Z (same as before) Otherwise, the collision order is Y→Z→X. In that sense, all neos "feel like X-facing", but the comparison is not really accurate. Ladders and vines can now be climbed by simply pressing jump. In general, it does not make more jumps possible, but they now feel easier to perform. In particular, vines can be climbed without a supporting block. Sneaking lowers the player's height even more (from 1.65m to 1.5m) The player can now fit under 1.5b ceilings. The player can be forced under a ceiling (by using a piston or trapdoor, for example) Under ceilings between 1.8b and 1.5b, the player enters a sneaking state. Under ceilings lower than 1.5b, the player enters a swimming state. Bugfix?: Blips have been patched: the player can no longer abuse stepping mechanics to gain artificial jump height. The player can still clip onto the side of blocks when landing against a wall. A new glitch was introduced: "blip-down", which happens when activating stepping on the edge of a block. Bug: The player can conserve X speed when colliding with a wall.
Blocks	Added Bamboo: Bounding box is 0.1875×1×0.1875, even for sprouts which appear 2 pixels wide. Placed in a (pre-determined) random position, which rarely matches with the traditional 16-pixels grid. Added Bells - 4 variants: Floor: simple 0.5×1×1 bounding box. Wall, Double-Wall, and Ceiling: same bell structure (0.5×0.5 base, 0.375×0.375 waist), each variant has a support beam of respective widths 0.125×0.8125, 0.125×1, 0.125×0.125. Added Campfires Bounding box is 1×0.4375×1. Damages the player when not sneaking (even when standing on the edge, unlike Magma blocks). Added Composter - same bounding box as the old cauldron, except the inner floor is 0.125b high. Added Grindstone - 0.5×0.75×0.75 stone that stands 1b tall, with two parallel legs that connect it to the floor. Can be placed against a wall or ceiling, in which case the bounding box is rotated accordingly. Added Lanterns - Centered bounding box that consists of a 0.375×0.4375×0.375 base, and a 0.25×0.5625×0.25 top. If hung to a ceiling, the bounding box is shifted 1 pixel upward (0.0625b). Added Lecterns - Centered bounding box that consists of a 1×0.125×1 base, and a 0.5×0.875×0.5 top. Added Scaffolding - a semi-tangible block that has similar climbing properties as ladders. Each Scaffolding has an physical "floor" at its top. If a Scaffolding has no blocks below, it gets an additional floor at its bottom (0.125b tall). Scaffoldings have no tangible walls or ceilings. Sneaking makes the floor intangible as well, unless there is no blocks below it. When sneaking inside a Scaffolding, the player moves downward. Added Stonecutter - 1×0.5625×1 bounding box. Added Sweet Berry Bushes - similar to cobwebs though less restrictive, but deal damage if the player is moving (past the sapling stage). Added Wither Rose - no bounding box, but inflicts the Wither effect to the player when standing next to it. Beds have a more accurate bounding box. The legs now have individual bounding boxes. Cauldrons have an even more accurate bounding box. The legs now have individual bounding boxes.
Other	Added separate "Mouse Controls" tab in Controls,

1.15 (Buzzy Bees)
