v1.4.0

CLI

• Improved error messages for ssh connect: when an SSH connection attempt fails, the client now fetches and prints the server's recent error logs (#5555).
• Increase the SSH server startup timeout from 10 to 45 minutes when a GPU accelerator is requested via databricks ssh connect --accelerator (#5569).
• Fix authentication falling back to the default profile in .databrickscfg when a host is already configured via the environment (e.g. DATABRICKS_HOST with DATABRICKS_TOKEN) (#5616).
• ssh: fix opening remote environment in Cursor, which previously hung on default-extension install and never opened the editor (#5619).
• Improve the error shown when databricks labs install cannot find a project's labs.yml: the message now explains that either the requested version does not exist or the project is not installable with the CLI, and links to the repository (#5559).

Bundles

• Remove API enum values and types that are still in development from the databricks-bundles Python package; these were never accepted by the backend (#5484).
• direct: Fix resolving a resource reference that is used more than once within the same field (#5558).
• Bundle variable references now accept Unicode letters in path segments (e.g. ${var.变量}). (#5532)
• Ignore remote changes for vector search direct_access_index_spec.schema_json to prevent drift when the backend normalizes the schema (#5481).
• Remove hidden, never-functional --existing-dashboard-id, --existing-dashboard-path, --existing-alert-id, and --existing-genie-space-id alias flags from bundle generate; use the documented --existing-id / --existing-path flags instead (#5591).
• engine/direct: Fix WAL corruption after two consecutive failed deploys (#5606).
• engine/direct: Don't open the deployment state WAL when a deploy's plan fails (#5607).
• Ignore unity catalog managed schema property defaults to avoid unnecessary drift (#5195).
• Add postgres_roles and postgres_databases resources to create Postgres roles and databases on a Lakebase branch (#5467, #5627).
• direct: Stop spurious recreate/rename on redeploy when the backend normalizes a resource's name-based ID (e.g. Unity Catalog lowercasing a schema or volume name) (#5599).
• Fix the generated pipeline README to suggest databricks bundle run <pipeline> --refresh <table> for running a single transformation; the previously documented --select flag is not supported by bundle run (#5252).
