## Version 9 Schematics
|
||||
## Updating CLI Apps
|
||||
|
||||
If your application uses the CLI, you can update to version 9 automatically with the help of the `ng update` script:
|
||||
|
||||
```
|
||||
ng update @angular/cli @angular/core
|
||||
```
|
||||
|
||||
If your application uses the CLI, you can update to version 9 automatically with the help of the `ng update` script.
|
||||
The script will run a series of small migrations that will transform the code of your application to be compatible with version 9.
|
||||
|
||||
If you're curious about the specific migrations being run (e.g. what code is changing and why), the guides below provide more context on each change and contain FAQs for common questions.

|
||||
### New Breaking Changes
|
||||
|
||||
- Angular now compiles with Ivy by default. See [Ivy compatibility section](#ivy).
|
||||
|
||||
- Typescript 3.4 and 3.5 are no longer supported. Please update to Typescript 3.6.
|
||||
|
||||
- tslib is now listed as a peer dependency rather than a direct dependency. Users not using the CLI will need to manually install tslib via `yarn add tslib` or `npm install tslib --save`.

## Ivy Compatibility
|
||||
|
||||
In Version 9, Angular Ivy is the default rendering engine. If you haven't heard of Ivy, you can read more about it in the [Angular Ivy guide](guide/ivy).
|
||||
|
||||
For help with opting out of Ivy, please see the instructions [here](guide/ivy#opting-out-of-angular-ivy).
