v1.26.0

Release v1.26.0 (2026-11-11)

AI Runtime

• air run reuses its existing workspace connection for config validation instead of opening a second one, which saves a TCP and TLS handshake per submission. (#7210)
• Speed up databricks air run for git-pinned code_source snapshots by compressing the archive in parallel, which substantially shortens packaging on large repositories. (#7402)
• Point the air run -h config agent-skill hint at the stable databricks-ai-runtime skill. (#7454)

Bundles

• Add DATABRICKS_BUNDLE_INIT_WORKSPACE_HOST_PROFILE, which names a profile whose host the workspace_host template helper returns instead of the selected profile's host. The profile must have the selected profile's workspace ID. (#7410)
• Fixed an explicit false on optional boolean fields (variables.*.sensitive, artifacts.*.dynamic_version, bundle.deployment.lock.force, workspace.azure_use_msi, replace_existing on postgres endpoints, databases and roles, and the experimental.* flags) being dropped, which hid it from bundle validate -o json and kept a target from overriding true with it. (#7412)
• Stop sending compute_size in the app update mask when the bundle does not declare it, so a deploy no longer resets a manually resized app to the default size. (#7461)
• lifecycle.depends_on can now target the grants or permissions of a resource, as schemas.foo.grants. (#7435)
• Add support for the feature_specs resource type, including UC grants on a feature spec. (#7364)

Dependency Updates

• Update the Go SDK to v0.197.0. (#7457)
• Bump Go toolchain to 1.27.4. (#7458)
