Binary file migration

This new release reduces the storage usage of binary files in half.

An online migration is included in version 5.5, allowing for minimal downtime as part of the upgrade. Before upgrading to Server Pro v6 make sure you're already running the latest version of Server Pro v5.5 (Release Notes 5.x.x) and have run the migration.

See full migration instructions.

MongoDB upgrade to v8

This release bumps the minimum MongoDB version to 8.0

If you're currently using MongoDB v6 or earlier, you'd need to update your versions one major version at a time (v6 → v7 → v8).

Please ensure you have a database backup before upgrading. In case of roll-back, you will need to restore the database backup.

For instructions on how to upgrade MongoDB v6 → v7 → v8 see our step-by-step guide here.

Redis upgrade to v7.4

This release also bumps the minimum Redis version to 7.4.

Update your REDIS_IMAGE in your config/overleaf.rc to REDIS_IMAGE=7.4.

New Features

• Link sharing now can be disabled with OVERLEAF_DISABLE_LINK_SHARING=true.

• OVERLEAF_MAINTENANCE_MESSAGE and OVERLEAF_MAINTENANCE_MESSAGE_HTML are now available to customise the title and content of the Maintenance page.

• OVERLEAF_USER_HARD_DELETION_DELAY and OVERLEAF_PROJECT_HARD_DELETION_DELAY can be configured (in milliseconds) to modify the deleted users/projects expiration delay (defaults to 90 days).

• Fixed footer rendering with links.

• Improved error messages on SAML login errors.

• Fixed audit log entry not added when a user's admin state is updated on SSO login.
