# Updates

- **Windows:** updates download and install automatically in the background. When one's ready, you'll see an **Apply** banner. Click it to restart into the new version whenever it's convenient; it isn't forced on you mid-flight. Applying closes CAVacars 2 and reopens it on its own, which can take a minute.
- **macOS / Linux:** you'll get a banner with a **Download update** button when a new version is available. Install it the same way you installed the current one.

You can also check for a new version at any time with **Check for updates** in the pilot menu (your name, top right).

<p class="callout warning">Try not to apply an update in the middle of a tracked flight. Tracking resumes after the restart, but there'll be a gap in your track and the flight may go to staff review. See [Flight tracking](https://kb.canadaairvirtual.ca/books/cavacars-2-pilot-guide/page/flight-tracking).</p>

### What's new

To see what changed in each version, open the pilot menu and choose **What's new**. It lists recent releases, newest first, with each change marked **New**, **Fix** or **Faster**. A red dot on your avatar means there's a release you haven't looked at yet; it clears when you open What's new.

The full history is on the [Changelog](https://kb.canadaairvirtual.ca/books/cavacars-2-pilot-guide/page/changelog) page. New versions are also announced in the CAVacars 2 channel on the CAV Discord.
