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.
