Version 1.2.8
- New Webhooks — point any form at a Zapier, Make, n8n, or custom endpoint via the new Webhook URL field. Every submission is POSTed as JSON, signed with HMAC-SHA256 (X-MxChat-Signature header) using a per-form secret so the receiver can verify authenticity.
- New WordPress action hook `mxchat_forms_submitted` fires after every successful submission, passing the labeled fields, form record, session ID, and page URL — for any WP plugin that wants to react in PHP.
- New Webhook Log page (under Forms) — last 100 delivery attempts per form with status badges, HTTP code, and response excerpt; filterable by form.
- Fixed Internal `MXCHAT_FORMS_VERSION` constant could drift from the plugin header version (used a hardcoded literal). It now derives from the plugin header automatically, so future releases always emit the correct version string for cache-busting and update reporting.
