# Migration
`Matter.Runner` related changes [#1254](https://github.com/liabru/matter-js/pull/1254):
* `Matter.Runner` now defaults to a fixed deterministic timestep and support for non-fixed timestep is removed
* Optionally set your performance budgets `runner.maxFrameTime` (see docs)
* Note that `Matter.Runner` can now call zero, one, or multiple engine updates and events per display frame (see docs)
* If needed set up your polyfill for `window.requestAnimationFrame`
* See `Matter.Runner` updated docs throughout
Performance related changes [#1238](https://github.com/liabru/matter-js/pull/1238):
* `Matter.Collision` use `collision.supportCount` instead of `collision.supports.length` for active support count
* `Matter.Pair` use `pair.contacts` instead of `pair.activeContacts`
* `Matter.Pair` use `pair.contactCount` instead of `pair.contacts.length` for active contact count
* `Pair.id` format has changed
