Plain Errors

Mostly plumbing under the August permissions rollout. SQL errors read the same everywhere, false access denials on BigQuery, Snowflake and PostgreSQL are gone, every saved tile records its data source, and MCP connections stop hanging.

Highlights

One SQL error contract across chat, CLI, MCP and dashboards
No more false datasource denials
Tiles record their data source
GPT-5.6 Luna default

New Features

GPT-5.6 Luna Default

GPT-5.6 Luna becomes the default for new chats, including Zero Data Retention mode. GLM-5.3 Flash is removed after failing tool-use tests.

Improvements

One SQL Error Contract

Validation failures, missing tables and columns, access denials and timeouts return the same clear messages whether the query ran in chat, the CLI, MCP, a dashboard tile or the API. Snowflake's combined missing-object message is classified too.

Tiles Record Their Data Source

Every tile saved from chat, the assistant, the CLI or MCP records which data source and thread it came from, so permission checks are exact and a connector cannot be deleted while dashboards depend on it.

Catalog Refreshes Keep Up

Scheduled catalog refreshes hand each connector to a durable workflow with its own retries, and stale catalog locks are reclaimed, so a backlog cannot stop the AI from seeing a new table.

Bug Fixes

False Datasource Denials Fixed

BigQuery project-qualified references, Snowflake names, PostgreSQL dollar-quoted strings and SIMILAR TO no longer trip the datasource scope check. PostgreSQL authorization now uses the real PostgreSQL grammar.

MCP Connections Stop Hanging

Subscription streams end after 120 seconds instead of running to the function timeout, so MCP clients no longer see requests that run for 13 minutes and return nothing.
