Passages provides support for the current version available as well as the two previous releases:
Per our Terms of Service (ToS), Passages requires customers to run supported versions of Passages. This enables us to provide you with the latest features as well as security and performance updates to maintain a smooth and secure browsing experience.
In addition to the current version, the two previous Passages versions are also supported in case you want to take your time updating to the most current release or are unable to update immediately.
If you have any questions, please contact our Passages Support Team at firstname.lastname@example.org.
