# Keeping your Angular projects up-to-date
|
|
|
|
Just like Web and the entire web ecosystem, Angular is continuously improving.
|
|
Angular balances continuous improvement with a strong focus on stability and making updates straightforward.
|
|
Keeping your Angular application up-to-date enables you to take advantage of leading-edge new features, as well as optimizations and bug fixes.
|
|
|
|
This document contains information and resources to help you keep your Angular applications and libraries up-to-date.
|
|
|
|
For information about our versioning policy and practices —including support and deprecation practices, as well as the release schedule— see [Angular versioning and releases](guide/releases "Angular versioning and releases").

## Checking your version of Angular
|
|
|
|
To check your application's version of Angular: From within your project directory, use the `ng version` command.
|
|
|
|
<a id="checking-version-angular"></a>
|
|
|
|
## Finding the current version of Angular
|
|
|
|
The most recent stable released version of Angular appears in the [Angular documentation](docs "Angular documentation") at the bottom of the left side navigation.
|
|
For example, `stable (v13.0.3)`.
|
|
|
|
You can also find the most current version of Angular by using the CLI command [`ng update`](cli/update).
|
|
By default, [`ng update`](cli/update)(without additional arguments) lists the updates that are available to you.
|
|
|
|
<a id="updating"></a>
|
|
|
|
## Updating your environment and apps
|
|
|
|
To make updating uncomplicated, we provide complete instructions in the interactive [Angular Update Guide](https://update.angular.io/ "Angular Update Guide").
|
|
|
|
The Angular Update Guide provides customized update instructions, based on the current and target versions that you specify.
|
|
It includes basic and advanced update paths, to match the complexity of your applications.
|
|
It also includes troubleshooting information and any recommended manual changes to help you get the most out of the new release.
|
|
|
|
For simple updates, the CLI command [`ng update`](cli/update) is all you need.
|
|
Without additional arguments, [`ng update`](cli/update) lists the updates that are available to you and provides recommended steps to update your application to the most current version.
|
|
|
|
[Angular Versioning and Releases](guide/releases#versioning "Angular Release Practices, Versioning") describes the level of change that you can expect based on a release's version number.
|
|
It also describes supported update paths.
