v0.45.0

This minor release adds alpha drift detection and remediation APIs, new localization and automerge controls, notification improvements, and several provider and execution fixes.

Highlights

• Added alpha drift detection, status, remediation, remediation history, and drift webhook APIs. These APIs are alpha and their request/response behavior may change in future releases. (#6360)
• Added runtime localization support with built-in English and Spanish catalogs plus custom YAML overrides. (#6506)
• Added automerge controls for default merge method and disabling automerge labels. (#6573, #6593)
• Improved GitHub team allowlists to honor team hierarchy. (#6365)

Alpha: Drift detection and remediation APIs

• Added alpha drift detection APIs, drift status API, drift remediation API, and remediation history/result read endpoints. (#6360)
• Added drift webhook notifications, including Slack and HTTP webhook support. (#6360)
• Added --enable-drift-detection for drift detection/status/history behavior.
• Added --enable-drift-remediation for destructive remediation apply.
• Drift APIs require API authentication with X-Atlantis-Token and repository allowlist authorization.
• Remediation action:"apply" requires cached positive drift with has_drift:true for the same repo/ref/base branch/project/path/workspace.
• Drift API inputs include ref, path, workspace, repository, and allowlist safety validation.
• Operators should test carefully before production use, especially with hooks, policy checks, allowlists, multi-project repos, and custom workflows.
