#### Experimental `t.try()` assertions
Thanks to the amazing work and patience of [@qlonik](https://togithub.com/qlonik) we're shipping a new assertion! `t.try()` lets you perform assertions and decide whether to commit or discard their outcome. All kinds of interesting things can be built on top of this, from fuzzy testers to new test interfaces and more.
We're excited to get this out there, but it's not quite done yet. For now you have to [_opt in_](https://togithub.com/avajs/ava/blob/master/docs/06-configuration.md#experiments) to this new feature. Being opt-in, we may make changes (breaking ones even!) until we feel this is stable.
To opt in, configure AVA with the following:
`package.json`:
```json
{
"ava": {
"nonSemVerExperiments": {
"tryAssertion": true
}
}
}
```
`ava.config.js`:
```js
export default {
nonSemVerExperiments: {
tryAssertion: true
}
};
```
We'd love to hear your feedback. Please join us in this issue: [#2250](https://togithub.com/avajs/ava/issues/2250)
Also, if you're looking to help out with the remaining issues so that we can ship this _without_ the opt-in, have a look at this project:
Thanks again [@qlonik](https://togithub.com/qlonik)!

#### Changes
- We've fixed some bugs to improve watch mode. [`ffa62ce`](https://togithub.com/avajs/ava/commit/ffa62ce94dec43f18a0c66623fa604036ef8dc48) [`9e8d28f`](https://togithub.com/avajs/ava/commit/9e8d28f4408b2e218e6a315d454dd68f66351351)

- AVA now handles stage-4 syntax like dynamic import, and stage-3 syntax like BigInt, numeric separators and class properties that are supported by V8. [`9baca8c`](https://togithub.com/avajs/ava/commit/9baca8ca4dcbf9512c1f7a33adaeedd37fc8eda2)
- AVA now supports dynamic import through our [stage-4](https://togithub.com/avajs/babel-preset-stage-4) preset.
- AVA now uses [`import-local@^3.0.2`](https://togithub.com/sindresorhus/import-local/releases/tag/v3.0.2) which fixes issues with Lerna projects.
- **For our TypeScript users**, we've changed the default type of `t.context` to `unknown`, [in line with TypeScript's changes in their 3.5 release](https://devblogs.microsoft.com/typescript/announcing-typescript-3-5/).
