Changelog

Fixed

Resolved OpenAI Responses API "No tool output found" errors during chained recursive tool calls and static-only turns. Static-skip is now disabled for Responses API because every `function_call` must be answered.
Managed-mode WP AI Client and AI Engine integrations now satisfy WordPress 7 AI plugin credential requirements, preventing false rejections for Ollama, OpenRouter, Mistral, Perplexity, and Replicate.
Removed redundant vector-DB addon initialization to prevent idle "OpenAI Vector Store ID is not configured" logs.
Resolved PHP 8.4 nullable-parameter deprecations in query and MCP helpers.
ChatML base now supports string-shaped `error` fields in API responses.

Added

Custom OpenAI-compatible provider for Ollama, LM Studio, vLLM, llama.cpp, LocalAI, and similar servers.
Built-in xAI/Grok provider with dynamic model fetching and fallback support.
Insights retention setting with daily cleanup for old log rows. Defaults to Never.
Embedding chunk metadata: source, partIndex, and partTotal, exposed through `mwai_embeddings_vector_metadata` for Pinecone, Qdrant, Chroma, and OpenAI Vector Store. PDF imports can now use the filename as the chunk title, and Modify Embedding can edit the new fields.
Code Engine static/dynamic Behavior now applies to Callable function snippets, skipping AI feedback when all calls are static.

Improved

Reworked onboarding with a default OpenAI environment, Knowledge provider chooser, one-click OpenAI vector store creation, no-key welcome message, and AI Assistant enabled by default.
Reworked Pro license management with a Modify License flow for Re-Validate, Modify, and Remove actions.
Hardened MCP handling by releasing PHP session locks, using proper trash hooks, deduplicating cache busts, enforcing `confirm_write` for non-read SQL, and purging LiteSpeed/WP Rocket caches after post writes.
Usage widget preferences for Price/Units/Queries and Daily/Monthly now persist across reloads.
Query and Reply tabs now point users to Settings > Others > Insights when data is unavailable.
Removed the legacy snippet-vault fallback and unused per-environment usage field.
