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 and detailed information on releases is posted on the BookStack blog here.
Before updating you should back up the database and any file uploads to prevent potential data loss.
Backup and restore documentation can be found here.
Updating is currently done via Git version control. To update BookStack you can run the following command in the root directory of the application:
git pull origin release && composer install --no-dev && php artisan migrate
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.
In addition, Clearing the cache is also recommended:
php artisan cache:clear php artisan config:clear php artisan view:clear
Check the below list for the version you are updating to for any additional instructions.
Version Specific Instructions
The below lists things you may need to be aware of when upgrading to a newer version of BookStack.
Updating to v21.04 or higher
Requirements Change - The minimum required PHP version has changed from 7.2 to 7.3. If you originally updated using the Ubuntu 18.04 installation script, the below commands should help you to upgrade to PHP8:
sudo add-apt-repository ppa:ondrej/php sudo apt update sudo apt install -y php8.0 php8.0-fpm php8.0-curl php8.0-mbstring php8.0-ldap php8.0-xml php8.0-zip php8.0-gd php8.0-mysql libapache2-mod-php8.0 sudo a2dismod php7.2 sudo a2enmod php8.0 systemctl restart apache2
User Reference Changes - References to users in URLs of profile pages, and within search filters, has been changed to be name (Slugified) based instead of ID based. Old links or saved search filters may no longer work as expected.
Updating to v0.31.0 or higher
Requirements Change - The minimum required PHP version has changed from 7.2 to 7.2.5. Additionally, the
Tidy PHP extension is no longer required.
GitLab Authentication - The
read_user scope will now be passed and is required on the “Application” setup within GitLab. Not having this scope may lead to errors when users attempt to authenticate via GitLab.
Security & IFrame Usage - By default BookStack will set headers to prevent usage within an iframe. You can set trusted iframe hosts through the
ALLOWED_IFRAME_HOSTS option in your
.env file. See the security page for more information on this option.
Updating to v0.30.6, v0.30.7 or higher
Security - v0.30.6 and v0.30.7 both address issues where page content could be visible to those without permission. If a chapter was visible to a user, but all of it’s pages were made not visible, then the details of these pages could be visible. Within the BookStack interface, the names of the pages and preview content could be seen. If the parent book was exported then this would include the content of the pages that had been restricted. If using BookStack v0.30.6, then all non-visible page content could be visible in plaintext exports. Please see the blog release pages for more details: v0.30.6, v0.30.7.
Updating to v0.30.5 or higher
Security - v0.30.5 fixes an potential vulnerability where a user with edit permissions could perform server-side requests using the export system. Additionally it was found that, if using standard email/password authentication, the system host URL could be manipulated on the forgot password form which could allow for email phishing attempts. Ensure you have set the
APP_URL option in your
.env file to help prevent this. Please see the blog release page for more details.
Updating to v0.30.4 or higher
Security - v0.30.4 fixes a couple of XSS vulnerabilities that could be exploited by untrusted users via page content and page link attachments. Please see the blog release page for more details.
Updating to v0.30 or higher
Security - Possible Privilege Escalation. During the v0.30 release cycle it was advised that current privilege escalation situations are not made clear when applying role permissions. Any user with a “Manage app settings”, “Manage users” or “Manage roles & role permissions” system permission assigned to one of their roles could technically alter their own permissions to gain wider access. A clear advisory of these cases has been added in the UI in v0.30 but admins are advised to review which users have these permissions with the above in mind.
LDAP & SAML Group Matching - During the v0.30 release cycle it was found that BookStack roles would be matched to LDAP/SAML groups based upon the role display name, which is expected, but only those roles with a matching “name” value would be considered. This “name” field was redundant, and has now been removed, but it would store a cleaned version the first-set name of the role. All roles will now be considered before being matched on name which may mean that roles which did not sync before, that would have been expected to based on their name, may now start to sync.
Updating to v0.29.3 or higher
Security - v0.29.3 fixes an issue where the names of restricted/private books could seen by those without permission, if added to a shelf. This issue was introduced in BookStack v0.28.0.
Updating to v0.29.2 or higher
Security - v0.29.2 fixes a XSS security vulnerability in the comment system, that was introduced in BookStack v0.18. Upon updating the command
php artisan bookstack:regenerate-comment-content should be ran to regenerate comment content to ensure that it is safe.
Updating to v0.28 or higher
Requirements Change - Minimum PHP version has increased from 7.0.5 to 7.2.
If you installed BookStack on Ubuntu 16.04 using the install script, You should be able to upgrade your PHP version to 7.4 by running the following commands:

on* html attributes. These will now be removed on page render unless you have set
ALLOW_CONTENT_SCRIPTS=true. If untrusted users has access to your BookStack you may want to scan for
<<space_char>>on in the HTML column of the pages table to identify any malicious intent.
Updating to v0.25.3 or higher
Security - On previous versions of BookStack it was possible to upload PHP files via the image upload endpoints. If you have a BookStack instance where untrusted users could upload image files, and you were using the default file storage option, It would have been possible for the user to access anything that the PHP process could. This would likely include, at minimum, any credentials stored in the
Updating to v0.25.2 or higher
Configuration Change - The .env option
REDIS_CLUSTER has now been removed. If more than one redis server is provided they will automatically be clustered by BookStack.
Updating to v0.25 or higher
