[2.1.0]
Update BookStack to 26.05
Full Changelog
Upgrade Notices - Folder Permissions - Due to some changes in how fonts are used for exports, after updating you may need to ensure that the storage/fonts folder (and all folders within that) are accessible & writable by the web-server. If you start seeing errors on PDF export after updating, it's likely this issue. See this page for guidance on setting permissions.
Revision Access - Revision access & visibility is now controlled separately to pages. In some cases, after upgrading, users may no longer be able to access revisions by default (for example, where users had access to view page content but had no role-level view permissions).
Added page contents view to page editor. (#6131, #4218)
Added API endpoints for browsing tags. (#6095, #5835)
Added custom font load handling for default PDF renderer. (#6109, #148, #719, #5770)
