4.1.10

• Fixed: Automatic nonce recovery for frontend AJAX requests — when a cached/expired nonce triggers 403, the widget fetches a fresh nonce and retries once.
• Improved: Added machine-readable invalid_nonce codes across chat, history, upload, and lead-form AJAX handlers for reliable frontend recovery.
• Improved: Cache purge hooks now cover updated/added/deleted widget-affecting options with a single-purge-per-request guard.
• Added: Anthropic Claude Fable 5 (claude-fable-5) in the model registry with current pricing metadata ($10 input / $50 output per 1M tokens).
• Updated: Gemini metadata refreshed against current API docs (including gemini-flash-latest and gemini-3.1-pro-preview-customtools aliases plus shut-down labels for retired Gemini 2.0/preview entries).

• Improved: Internal provider flows now resolve default models from the central registry (avoids hardcoded fallback IDs).

4.1.8

• Added: Admin AJAX diagnostic runner that uses the selected bot/provider/model configuration and returns a copyable JSON report.

• Added: Multiple Lead Lists — create independent lists, each with its own fields, destination, form design, bot assignment, and notifications.
• Added: Form Appearance customization per list — display mode (full/compact), custom HTML header, submit button text, success message, background color, and button color.

• Added: Per-bot Quick Questions configuration — enable/disable and manage questions from Bots → Extras with dynamic add/remove fields and auto-save.

3.0.9

• Added: File & Image Uploads — visitors can now send photos (JPG, PNG, WebP) and PDF documents directly in the chat widget via a new 📎 attachment button.
• Added: AI Vision support — uploaded images are sent to the AI model's vision capability (GPT-4o, Claude Sonnet/Opus, Gemini Pro/Flash) for real-time visual analysis.
• Added: PDF text extraction — uploaded PDFs have their text extracted automatically and injected into the conversation context.
• Added: Automatic image optimization — uploaded images are resized (max 1536px) and compressed to reduce API costs and speed up processing.

• Added: Per-bot upload configuration — enable/disable uploads, select allowed file types (PDF, JPG, PNG, WebP), and set max file size (1–20 MB) independently for each bot.

Third-party plugins can hook into aichat_after_purge_cache.
• Added: View and Edit buttons for indexed documents in Training → Context — inspect individual chunks, spot indexing errors, and surgically edit specific chunks with automatic re-embedding on save.

3.0.7

• Added: GDPR Consent now supports two modes — classic accept button or an email form gate that captures visitor contact details before the chat starts.
• Added: Email form mode collects email (required), name, and phone (both optional toggles with configurable placeholders).
• Added: GDPR Contacts tab under Leads — view, search, delete, bulk-delete, and export contacts captured via the email form. No plan limits apply.
