## ▲.● matter.js `0.18.0`
Release notes for `0.18.0`. See the release [readme](https://github.com/liabru/matter-js/blob/0.18.0/README.md) for further information.
### Highlights ✺
- **Up to ~40% performance improvement (on average measured over all examples, in Node on a Mac Air M1)**
- Replaces `Matter.Grid` with a faster and more efficient broadphase in `Matter.Detector`
- Reduced memory usage and garbage collection
- Resolves issues in `Matter.SAT` related to collision reuse
- Removes performance issues from `Matter.Grid`
- Improved collision accuracy
- Improved API and docs for collision modules
- Improved [documentation](https://brm.io/matter-js/docs/) pages
- Added note about avoiding Webpack [performance problems](https://github.com/liabru/matter-js/blob/master/README.md#install)
### Changes ✲
See the release [compare page](https://github.com/liabru/matter-js/compare/0.17.1...0.18.0) and the [changelog](https://github.com/liabru/matter-js/blob/0.18.0/CHANGELOG.md) for a detailed list of changes.
### Migration ⌲
- Behaviour and similarity is in practice the same (a fractional difference from improved accuracy)
- API is the same other than:
- [Matter.Detector](https://brm.io/matter-js/docs/classes/Detector.html) replaces [Matter.Grid](https://brm.io/matter-js/docs/classes/Grid.html) (which is now deprecated but will remain for a short term)
- [render.options.showBroadphase](https://brm.io/matter-js/docs/classes/Render.html#property_options.showBroadphase) is deprecated (no longer implemented)
- [Matter.SAT](https://brm.io/matter-js/docs/classes/SAT.html) is renamed [Matter.Collision](https://brm.io/matter-js/docs/classes/Collision.html)
- [Matter.SAT.collides](https://brm.io/matter-js/docs/classes/SAT.html#method_collides) is now [Matter.Collision.collides](https://brm.io/matter-js/docs/classes/Collision.html#method_collides) with a slightly different set of arguments
### Comparison ⎄

## ▲.● matter.js `0.17.0`
Release notes for `0.17.0`. See the release [readme](https://github.com/liabru/matter-js/blob/0.17.0/README.md) for further information.
### Highlights ✺
- Added performance and stats monitoring overlays to `Matter.Render`
- See the [stats demo](https://brm.io/matter-js/demo/#stats) or enable [render.options.showPerformance](https://brm.io/matter-js/docs/classes/Render.html#property_options.showPerformance) and [render.options.showStats](https://brm.io/matter-js/docs/classes/Render.html#property_options.showStats)
- Stats shown include
- render frequency (e.g. `60 fps`)
- engine delta time (e.g. `16.66ms`)
- engine execution duration (e.g. `5.00ms`)
- render execution duration (e.g.` 0.40ms`)
- effective play speed (e.g. `1.00x` is real-time)
- various other engine internal stats for debugging
- Improved [documentation](https://brm.io/matter-js/docs/) pages
- Added [Common.setDecomp](https://brm.io/matter-js/docs/classes/Common.html#method_setDecomp) and [Common.getDecomp](https://brm.io/matter-js/docs/classes/Common.html#method_getDecomp) to fix [bundler issues](https://github.com/liabru/matter-js/issues/981)
- Added docs for all [Matter.Render options](https://brm.io/matter-js/docs/classes/Render.html#properties)
- Migrated usage of `Matter.World` over to `Matter.Composite` (more info in [docs](https://brm.io/matter-js/docs/classes/World.html))
- Migrated, deprecated and removed various old functionality (see the [changelog](https://github.com/liabru/matter-js/blob/0.17.0/CHANGELOG.md) for details)
