v1.6.0

Release v1.6.0

CLI

• ssh connect now accepts a --base-environment flag to run a serverless session on a custom base environment. It takes an env.yaml path, a workspace-base-environments/... resource ID, or a base environment display name, and is rejected together with --environment-version or --cluster (#5706).
• databricks aitools install is now plugin-first: it installs the Databricks plugin through each agent's own CLI (Claude Code, Codex, GitHub Copilot) instead of copying raw skill files. Agents without a plugin (OpenCode, Antigravity) still get skill files, and Cursor prints the /add-plugin databricks step. Use --skills-only to force raw skill files for every agent, or --path <dir> to write skills to a directory (#5738).
• databricks labs list now only shows projects that can be installed (#5560).

Bundles

• direct: Fixed persistent drift on model_serving_endpoints caused by the traffic_config field (#5708).
• direct: Fix spurious update when apply_policy_default_values: true is set on job task, for-each-task, or job cluster new_cluster (#5731). Also fix spurious updates for for-each-task clusters due to missing backend defaults for data_security_mode, node_type_id, driver_node_type_id, driver_instance_pool_id, enable_elastic_disk, and enable_local_disk_encryption.
• direct: Cluster resize now falls back to regular update if resize fails due to INVALID_STATE (#5716).
• bundle generate dashboard now honors the --key flag when naming the generated resource, and rejects combining --existing-path, --existing-id, and --resource instead of silently ignoring all but one (#5492).
• Fixed bundle deployment migrate failing on model_serving_endpoints/database_instances with permissions (regression since v1.5.0) (#5775).
• After a terraform deploy, the CLI now dry-runs a migration to the direct engine (writing nothing locally or remotely) and reports the outcome via telemetry, warning if the migration could not be completed (#5797).

Dependency updates

• Bump github.com/databricks/databricks-sdk-go from v0.147.0 to v0.152.0 (#5773).
• Bump Terraform provider from v1.118.0 to v1.120.0 (#5792).
