Recent releases
Release history
- Gemini Interactions API engine as the default for Google, with streaming, function calling, and in-chat image generation (classic API kept as a fallback).
- Google Search and Maps grounding as Gemini chatbot tools, plus a setting to fall back to the standard Gemini API.
- MCP server support to Realtime voice chatbots — tools were selectable but previously did nothing — and the model now speaks tool results aloud.
- `mwai_mcp_mutate` action that fires after any content-mutating MCP tool, letting integrations purge caches, reindex, or audit.
- `raw` option to the MCP `wp_get_option` tool to read directly from the database, bypassing object cache and filters.
- `author__not_in` to MCP `wp_get_posts`, and a `content_format=prose` option to `wp_get_post`/`wp_get_post_snapshot` that strips block-attribute JSON to reduce token usage.
- `wp_create_post` MCP tool no longer corrupts shortcode and HTML content via the markdown parser.
- MCP log entries mislabeled as OAuth; admin and bearer calls now display correctly.
- Streaming parallel tool calls leaving a null in the `tool_calls` array, which broke function calling on strict providers.
- MCP `wp_get_posts`, `wp_get_media`, and `wp_get_comments` filters by author, `user_id`, and email were accepted but silently ignored.
- `wp_update_option` now decodes JSON-string array values into real arrays before saving, preventing corruption of array options like `sticky_posts`.
- Chatbot events panel is now scrollable and error messages are dismissable.
- Removed the legacy MCP SSE transport, keeping only the Streamable HTTP endpoint.
- Enabled function calling for Mistral.
- Uploaded images now fill the message bubble width in the chatbot across all themes.
- MCP post tools now accept `ID`, `post_id`, or `id` interchangeably, and `wp_update_post` accepts top-level fields with clearer error messages.
View changelog
- Path traversal vulnerability in create_image and prevented chatbot discussions from being taken over by another logged-in user.
- Add-ons were reported as disabled whenever options were fetched outside the admin context.
- Max Tokens entered with a thousands separator (e.g. the Danish "64.000") was read as 64 and capped responses.
- Content Aware placeholders now resolve automatically in chatbot instructions without requiring a toggle.
- Setup Assistant no longer shows "Connect an AI Provider" as incomplete when only the Fast model is deprecated.
- Realtime instructions now resolve placeholders like {FIRST_NAME} into their values.
- MCP tools generated from WordPress REST endpoints could break Google Gemini due to enum on non-string types.
- Changing the type of an AI environment now drops fields from the previous type (endpoint, region, deployments), preventing engines from calling the wrong provider's endpoint.
- The "Default AI Environment not configured" warning no longer appears when a Chroma embeddings environment generates its own vectors.
- The Usage widget on the Dashboard no longer overflows its panel when numbers are wide.
- Anthropic's streaming ping keepalive events are now ignored instead of being logged as an unknown stream data type.
- Reworked embeddings sync — pages are no longer marked stale without real changes, the background task (now called Maintenance) runs for all environments, processes batches within a time budget, no longer gets blocked by a failing vector, and can be disabled in Settings > Knowledge > Sync Settings.
- API key and token fields are now masked with an eye toggle to reveal them.
- Marked the original GPT-5 models (gpt-5, gpt-5-mini, gpt-5-nano, gpt-5-pro) as deprecated per OpenAI's December 10, 2026 shutdown.
- The fullscreen resize button now uses thin corner-bracket icons that match the close button.
- OpenAI Vector Store document uploads now accept multiple files at once.
- User Memory added to the add-ons list.
- Optional capability filter for get_chatbots() to fetch only chatbots whose model supports function calling.

- `wp_alter_post` regex mode now handles patterns containing "/" (e.g. Gutenberg block markers) and returns the actual PCRE error instead of a generic one.
