Changelog
Fixes Chat Settings not syncing to the public widget, the agent name/avatar not applying, and several Email Settings and Saved Replies issues. Adds optional Business Domain and Contact Info fields in General Settings. Backward compatible — no migration required and existing data is untouched.
1.5.2 (June 18, 2026)
New Features:
* Added Business Domain and Contact Info fields in General Settings — the AI now uses these to describe what your business does and how to reach you, for more accurate, on-brand replies
Bug Fixes:
* Fixed Chat Settings not syncing to the public chat widget — header and launcher colors, header text color, send-button icon color, online indicator, auto-open, and the Support Ticket / Contact Us links now apply correctly on the live widget
* Fixed the configured agent avatar not appearing in the live chat and admin preview
* Fixed the AI agent name always showing as “Support” instead of the name set in Chat Settings
* Fixed multi-line System Prompt and error-message text losing line breaks when saved
* Fixed Email Settings silently saving an empty or invalid From address; From Name and From Email are now validated and fall back to the site admin email and site title
* Fixed Reply-To now correctly defaulting to the From address when left blank
* Fixed Saved Replies so keywords can be cleared, new replies default to a valid language, and the analytics keyword bar shows the correct color
Improvements:
* Saved Replies now also guide AI answers — when a visitor’s question doesn’t exactly match a saved reply, the AI can still answer using your saved replies as approved reference, so reworded questions (“when are you open?” vs “what are your business hours?”) get accurate answers
* Added Header Text Color and Send Button Icon Color controls in Chat Settings
* Settings now return clear validation errors instead of silently saving partial or invalid values
1.5.1 (June 15, 2026)
Bug Fixes:
* Fixed two-way CSS styling conflicts between the chatbot widget and WordPress themes — all widget classes are now fully namespaced with zeno_chatbot– prefix
* Fixed user message bubble losing padding on the right side
Improvements:
* Removed unavailable Claude Fable 5 model from Anthropic model list
* Existing installations configured with Fable are automatically remapped to Claude Opus 4.8
1.5.0 (June 13, 2026)
New Features:
* Added Anthropic Claude integration — supports Claude Opus 4.8, Claude Sonnet 4.6, and Claude Haiku 4.5 with extended thinking support
Improvements:
* Lowered minimum PHP requirement from 8.0 to 7.4 — the plugin now runs on every PHP version WordPress supports (7.4–8.3, continuously tested)
* Major dashboard performance overhaul: statistics and charts now use single aggregate queries instead of per-conversation and per-day queries (up to 100x fewer database queries on busy sites)
* Improved data fetching and LLM tool call handling for more reliable AI responses
* Faster chat replies: saved-reply matching loads embedding data only when semantic matching actually runs, and repeated user messages reuse cached embeddings
* Reduced AI token usage: knowledge-base context sent to the AI is now size-capped per request
* Chat widget assets (JS/CSS) are no longer loaded on the frontend when the floating widget is disabled
* Conversation summaries are now generated in the background instead of delaying chat close and admin replies
* Content index rebuilds now process posts in batches, keeping memory usage flat on sites with large content libraries
* Faster failover on embedding API issues (request timeout reduced from 30s to 10s)
Bug Fixes:
* Fixed admin pages incorrectly rendering in a PHP error state (php-error body class) caused by a suppressed connection warning from the asset dev-server probe
* Fixed a fatal error on PHP 7.4 caused by PHP 8.0+ type declarations in the hook dispatcher
1.4.0 (April 26, 2026)
New Features:
* Added support for OpenAI GPT-5.5, GPT-5.4, GPT-5.4 Mini, GPT-5.4 Nano, GPT-5, GPT-5 Mini, and GPT-5 Nano models
* Added support for Google Gemini 2.5 Pro model
* Improved extensibility for third-party developers
Improvements:
* Updated default AI model to GPT-5 Mini for better cost-performance balance
* Deprecated older models (GPT-4o, GPT-3.5 Turbo, GPT-4 Turbo, GPT-4.1 Nano, ChatGPT-4o) now labeled in settings UI
* Improved PHP 8.4 compatibility
* Improved Pro extension compatibility
Bug Fixes:
* Fixed fatal database error on fresh WordPress installations caused by Action Scheduler tables not being created during activation
* Fixed “unexpected output during activation” warning
* Fixed Action Scheduler initialization timing when activating on a fresh site
1.3.2 (February 24, 2026)
Bug Fixes:
* Prevented Action Scheduler database table-missing errors during scheduler boot by skipping Action Scheduler queries until its tables exist
* Hardened recurring scheduler self-healing by using Action Scheduler’s ensure-recurring hook when supported and best-effort activation seeding for maintenance/cleanup jobs
* Fixed scheduler boot re-entrancy that could recurse into cleanup scheduling and exhaust memory when Action Scheduler was already initialized
1.3.0 (February 17, 2026)
New Features:
* Internal Content expansion: added dedicated Sitemap, Product Index, and Knowledge Notes data sources in settings
* Sitemap indexing workflow: auto/manual source selection, chunked processing, progress modal, and completion summary
* Product indexing workflow: field-selectable WooCommerce indexing with chunked processing and dedicated product JSON output
* Conversation lifecycle controls: added dedicated Conversation Settings panel with auto-close and auto-summary options
* Conversation summaries: added summary status/actions in conversation details with retry/regenerate support
Improvements:
* Unified Internal Content overview loading into a single API payload
* Migrated indexing workflows to service-driven architecture with contract-locked response adapters
* Added transparent derived-text cache invalidation hooks across indexed knowledge sources
* Added consistency checks for scheduler usage, indexing contracts, and critical security invariants
Bug Fixes:
* Fixed invalid REST handler mapping for conversation status/reply endpoints
* Fixed markdown heading rendering in Knowledge Notes preview
* Fixed class loading regressions by enforcing Composer autoload flow and authoritative dump workflow
* Fixed summary generation transcript grounding to improve summary quality
Security:
* Strengthened chat session integrity with signed session payload verification
* Hardened public markdown rendering with strict sanitization and safe link protocol enforcement
* Reduced public error leakage by returning generic client-facing error responses
* Enforced scoped chat/history rate limiting and improved abuse controls
* Added same-site sitemap traversal enforcement for root and nested sitemap URLs
