# Update Cover

Diffblue releases product updates about every two weeks to continuously provide you with product enhancements and new features. Note that:

* If needed, check the details for the latest updates, and even the older ones - see [What's new](/updates-and-upgrades/whats-new.md).
* When you update, you'll always be updated to the latest version.
* If you're using Cover Plugin **and** Cover CLI, we recommend that you update both products to the latest version.

{% tab title="Cover Plugin" %}
{% hint style="info" %}
Updating Cover Plugin may take a few minutes to complete and will require an IDE restart - you won't be able to create any tests for your projects while the update is progressing.
{% endhint %}

1. In IntelliJ, go to `File > Settings > Plugins` (Windows/Linux) or `IntelliJ IDEA > Preferences > Plugins` (macOS), highlight the Diffblue Plugin and click `Update` in the details panel.
2. When you're ready, click `Restart IDE` to complete the update.
   {% endtab %}

{% tab title="Cover CLI" %}
{% hint style="info" %}
Updating Cover CLI may take a few minutes to complete and you won't be able to create any tests for your projects while the update is progressing.
{% endhint %}

**Windows:**

1. Using the link provided by Diffblue, download the new Diffblue Cover CLI file - either the `.exe` installer or `.zip` archive, as needed.
2. If you use the installer, run the `.exe` installer and follow the on-screen prompts.
3. If you use the archive file, extract the `.zip` file to your existing Cover CLI folder. Note that if you'd like to retain the previous release files, move these to a different folder first or create a new folder for the new version. Make sure to update the `PATH` or `DCOVER` environment variable configured during your original install, if needed.
4. When your done, restart your PC. Once complete, run `dcover version` to check the install and `PATH` configuration - if all is OK, Cover will display the current version.

**Linux/macOS:**

1. Using the link provided by Diffblue, download the Diffblue Cover CLI `.zip` file.
2. Unzip the Cover CLI zip file to an appropriate installation location using the following example commands. Note that if you'd like to retain the previous release files, move these to a different folder first or create a new folder for the new version. Make sure to update the `PATH` environment variable configured during your original install, if needed.\\

   ```
   mkdir ~/bin
   cd ~/bin
   unzip ~/diffblue-cover*.zip
   export PATH=$PATH:~/bin
   ```

   \
   **Reminder:** Make sure that the `PATH` environment variable is set permanently according to your operating system instructions.
3. Once complete, run `dcover version` to check the install and `PATH` configuration - if all is OK, Cover will display the current version.
