Complete conversation persistence

User input, AI replies, failures and stopped results are stored in PostgreSQL and associated with their conversation.

Improved

Apps and conversations appear in a tree, making recent status and past turns easier to find.

Fixed

Conversation ownership checks

Every message verifies that its conversation belongs to the current app, preventing orphaned or misdirected records.

An upgraded default model and reasoning controls provide more reliable planning, coding and verification for complex full-stack work.

New

Flagship model

Preview node scheduling

The control plane assigns preview builds according to node health and load.

New

Versioned deployments

Each build creates a distinct preview version with its status, image and logs.

A shared domain routes traffic to the correct container without exposing node ports.

Fixed

Lease recovery

Offline nodes and expired leases are requeued automatically so tasks do not remain stuck.
