SynaptikCMS v1.3

[1.3] — 2026-07-17

Added

• Plugin system — SynaptikCMS now supports standalone plugins: self-contained folders in /plugins (each with a plugin.json manifest) that extend the site without modifying core files. Plugins hook into the existing theme API (add_theme_action, apply_theme_filters) for front-end behaviour, and into a new lightweight hook system for admin integration.
• Extensions page (Tools → Extensions) — lists every plugin detected at the CMS root, with one-click activate/deactivate. Activation state is stored in plugins.json.
• Active plugins can register their own entry in the admin sidebar, and render a full page inside the standard admin layout (sidebar, top bar, footer) via a new generic plugin page router — no plugin needs to reimplement the admin chrome.
• First plugin built on this system: Booking, a standalone appointment-booking module (separate download, not bundled with core) — public calendar with weekly recurring availability and date exceptions, per-type appointment durations, admin approval workflow (pending/confirmed/refused/cancelled), and automatic email notifications with .ics calendar attachments for both the client and the site admin, including optional phone-callback reminders.

Changed

• Admin WYSIWYG editor: added a delete button to collapsible sections and tab-group tabs (hover the section header), retroactively applied to existing content on load
• Admin WYSIWYG editor: added a colour-picker button next to the delete button on collapsible sections and tab-group tabs, letting you change a section's accent colour instantly without reopening the source view

New Plugins

• Booking - Standalone appointment booking module with calendar availability, admin approval workflow, and ICS calendar invites.
• Newsletter - Email newsletter signup with double opt-in and a manual article digest sender.
• Redirects - Manual 301/302 URL redirects, plus an optional 404-to-home fallback.
