8 BookStack is updated regularly and is still in beta although we do try to keep the platform and upgrade path as stable as possible. The latest release can be found on [GitHub here](https://github.com/BookStackApp/BookStack/releases) and detailed information on releases is posted on the [BookStack blog here](https://www.bookstackapp.com/blog/tag/releases/).
10 **Before updating you should back up the database and any file uploads to prevent potential data loss**. <br>
11 Backup and restore documentation can be found [here](/docs/admin/backup-restore).
13 Updating is currently done via Git version control. To update BookStack you can run the following command in the root directory of the application:
16 git pull origin release && composer install && php artisan migrate
19 This command will update the repository that was created in the installation, install the PHP dependencies using `composer` then run then update the database with any required changes.
21 In addition, Clearing the cache is also recommended:
24 php artisan cache:clear
25 php artisan view:clear
28 Check the below list for the version you are updating to for any additional instructions.
