---

- **added** — New registerAdapter() API to extend animate() and utils.set() to non-DOM targets
- **added** — New built-in three.js adapter imported as a side-effect from animejs/adapters/three to animate Object3D, materials, lights, cameras, audio nodes, UniformNode (TSL) and instanced meshes
- **added** — Auto-grid stagger mode now supports 3D layouts using {x, y, z} coordinates or an explicit grid: [columns, rows, depth] triplet
- **changed** — The from parameter now accepts [x, y, z] normalized coordinates and axis now accepts 'z' for 3D grid origins
- **added** — New jitter parameter to add a random offset to staggered values, either a single number or a [start, end] range
- **added** — New seed parameter to make jitter and from: 'random' reproducible
- **changed** — Color animations now blend RGB channels in pseudo-linear space for smoother, more even transitions
- **fixed** — Fix a flicker that could appear randomly between iterations of reversed loops
- **fixed** — Fix a flicker that could appear randomly on alternate loops when using non-integer duration values
- **fixed** — Fix a backward seek leaving a timeline child stuck at its end value when all its properties share the same delay
- **fixed** — Fix a timeline child whose delay is longer than its duration overwriting a later sibling's value on a forward seek
- **fixed** — Fix stale values when seeking a timeline whose children animate the same property through delayed tweens, most visible with staggered jitter delays
- **fixed** — Fix an implicit from value resolving to a stale value when an overridden tween sits earlier in the chain
- **fixed** — Improve performance when building large timelines with many overlapping .add() calls on the same property, and fix a case where such a timeline could cancel itself
- **fixed** — Fix a floating point precision issue producing incorrect intermediate values in keyframe arrays
- **fixed** — Fix scrubbing backward past the start of a keyframe sequence not restoring the first keyframe's from value
- **fixed** — Fix scrubbing forward past the end of a keyframe sequence leaving the target stuck on a previous keyframe's value
- **fixed** — Fix sequential keyframes occasionally detected as overlapping because of floating point drift, leaving the target stuck on the wrong value when scrubbing
- **fixed** — Fix function-based and CSS variable from values in object form ({ from, to }) not re-resolving on refresh()
- **fixed** — Fix stretch() not correctly scaling animations that use keyframes

##### New Features

- **Adapters**
  - New `registerAdapter()` API to extend `animate()` and `utils.set()` to non-DOM targets (learn more: https://animejs.com/documentation/adapters)
- **Three.js adapter**
  - New built-in three.js adapter, imported as a side-effect from `animejs/adapters/three`, to animate `Object3D`, materials, lights, cameras, audio nodes, `UniformNode` (TSL) and instanced meshes (learn more: https://animejs.com/documentation/adapters/three)
- **Stagger**
  - Auto-grid mode now supports 3D layouts, using `{x, y, z}` coordinates or an explicit `grid: [columns, rows, depth]` triplet
  - The `from` parameter now accepts `[x, y, z]` normalized coordinates and `axis` now accepts `'z'` for 3D grid origins
  - New `jitter` parameter to add a random offset to staggered values, either a single number or a `[start, end]` range
  - New `seed` parameter to make `jitter` and `from: 'random'` reproducible

##### Bug Fixes and improvements
- **Color**
  - Color animations now blend RGB channels in pseudo-linear space for smoother, more even transitions (intermediate colors differ slightly from previous versions)
- **Render**
  - Fix a flicker that could appear randomly between iterations of reversed loops
  - Fix a flicker that could appear randomly on alternate loops when using non-integer duration values
- **Timeline**
  - Fix a backward seek leaving a timeline child stuck at its end value when all its properties share the same delay
  - Fix a timeline child whose delay is longer than its duration overwriting a later sibling's value on a forward seek
  - Fix stale values when seeking a timeline whose children animate the same property through delayed tweens, most visible with staggered `jitter` delays
  - Fix an implicit `from` value resolving to a stale value when an overridden tween sits earlier in the chain
  - Improve performance when building large timelines with many overlapping `.add()` calls on the same property, and fix a case where such a timeline could cancel itself
- **Keyframes**
  - Fix a floating point precision issue producing incorrect intermediate values in keyframe arrays
  - Fix scrubbing backward past the start of a keyframe sequence not restoring the first keyframe's `from` value
  - Fix scrubbing forward past the end of a keyframe sequence leaving the target stuck on a previous keyframe's value
  - Fix sequential keyframes occasionally detected as overlapping because of floating point drift, leaving the target stuck on the wrong value when scrubbing
- **Animation**
  - Fix function-based and CSS variable `from` values in object form (`{ from, to }`) not re-resolving on `refresh()`
  - Fix `stretch()` not correctly scaling animations that use keyframes
- **Scroll**
  - Fix a `getBoundingClientRect` crash that could happen when a scroll container resized before its target was ready
- **Engine**
  - More accurate frame scheduling that no longer drops frames arriving slightly early because of `requestAnimationFrame` jitter
  - Faster `engine.speed` and `engine.timeUnit` updates that skip unnecessary work when the value does not actually change
