v1.19.0

CLI

• Honor CLAUDE_CONFIG_DIR in aitools commands. (#6838)
• Added --ttl and --no-expiry flags to databricks postgres create-branch so a branch's expiration can be set without hand-writing a --json spec. --ttl accepts the REST API duration form (604800s), a Go duration (168h), or day/week units (7d, 3w); --no-expiry creates a branch that never expires. One of --ttl, --no-expiry, or a spec expiration in --json is required. (#6313)
• databricks ssh connect serverless sessions now provide Claude Code and Codex configured with Unity Gateway out of the box. (#6885)

AI Runtime

• Add databricks air images push (Preview) to configure Docker authentication and push container images to Databricks Artifact Registry. (#6869)
• air run now grants the configured permissions on the MLflow experiment as well as the job. (#6870)

Bundles

• Add libraries field to clusters. (#6831)
• Error out when a configured workspace_id does not match the connected workspace, instead of silently using it in resource URLs emitted by bundle summary. (#6754)
• Fix spurious recreation of Lakebase (Postgres) branches, roles, and catalogs when the referenced project is updated in place: an in-place project change (e.g. display_name) no longer forces a delete + create of resources that reference the project's or branch's name. (#6865)
• Direct engine now detects and applies an explicitly configured integer zero (e.g. gcp_attributes.local_ssd_count: 0) added to a resource first deployed without the field. (#6867)
• Migrate existing Terraform deployment state to the direct engine before deploying (previously done after a Terraform deploy), so the deploy runs on the direct engine. (#6749)
• The postgres_snapshot_schedules resource (introduced in v1.16.0) is now marked Beta and is no longer available in PyDABs, matching the other postgres_* resources; configure it in YAML instead. (#6887)
