Changelog
Fixed
- 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.
Improved
- 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.
Added
- User Memory added to the add-ons list.
- Optional capability filter for get_chatbots() to fetch only chatbots whose model supports function calling.
