This release adds three new policy types — Thunderbird, Microsoft Edge for Business, and Firewalld zones — alongside a full web UI overhaul, finer-grained RBAC, and a dedicated security hardening pass. The complete changelog is on the GitHub release page.Thunderbird policy typeMozilla Thunderbird can now be managed on enrolled desktops with the same mechanism used for Firefox ESR. The agent writes the managed policies.json that Thunderbird expects, merged from all bound policies, and removing the last policy restores the original file. Flatpak installations are detected and enforced alongside RPM/DEB installations, and the managed file is protected by the tamper watcher — external edits are detected and immediately restored. The web UI ships a full policy editor with the complete Thunderbird policy catalogue.Microsoft Edge for Business policy typeFor fleets running Edge on Linux, the agent writes bor_managed.json into each Edge managed-policy directory and cleans it up from every directory when the last bound policy is removed. The web UI provides a tree-based editor with the Edge policy catalogue, JSON validation, and a setting preview before enabling.Firewalld zone policy typeThe new Firewalld policy type manages firewalld zones on enrolled nodes: services, ports, forward ports, rich rules, masquerade, interfaces, sources, and the zone target. The agent writes zone XML to /etc/firewalld/zones/, validates it with firewall-cmd --check-config, and reloads firewalld. Like all other managed files, the zone files are tamper-protected.Polkit: variable conditionsPolkit rules now support variable conditions via action.lookup(), so a rule can match on action variables — for example allowing mounts only for removable drives. Also fixed: multiple action IDs in one rule are now correctly joined with ||.Per-action RBACUser and role administration is now guarded by per-action permissions instead of a single blanket permission, allowing finer-grained delegation of admin duties.Web UI overhaulA full modernization pass over the PatternFly 6 interface, spanning several UX sprints. The dashboard shows the new look — grouped sidebar navigation, a single left-aligned page title, and stat tiles that drill down to pre-filtered lists: click Offline and you land on the Nodes page already filtered to offline nodes.The highlights:URL routing — every page has a real URL with working browser back/forward and deep links; expired sessions redirect to login; a global error boundary prevents white-screen crashes.Full-page policy editor — the policy editor is now a routed page (/policies/:id/edit) instead of nested modals.Policy safety rails — unsaved-changes guard, confirmation for destructive type changes, JSON validation for Chrome/Edge values, a read-only Configuration view for released policies, and setting previews in the tree editors.Scalable lists — server-side pagination, filtering, and sorting for Nodes and Compliance; search, sorting, and empty states across all list pages.Destructive-action protection — type-to-confirm dialogs for all resource deletes, plus server-side guards that prevent deleting, disabling, or demoting the last Super Admin.Accessibility (WCAG 2.2 AA) — accessible tree roles in the policy editors, aria-live status messages, focus-ring and dark-mode/high-contrast correctness via PatternFly 6 design tokens, and an accessibility lint gate in CI.The policy editor is now a routed, full-width page instead of stacked modals, with room for the tree-based editors behind each policy type:Node and compliance lists are paginated, filtered, and sorted server-side, so fleets with thousands of nodes stay fast:Plus many quality-of-life changes: policies can be released/unreleased directly from the list view, backup codes for MFA can be copied or downloaded, the login form gained a password reveal toggle a
