## Executive Summary (TL;DR)
dbt Core v1.12.3. Source highlight: dbt-core 1.12.3 - August 20, 2026

## Bug Fixes
- Send the `x-ms-blob-type: BlockBlob` header and accept `201 Created` when uploading artifacts to an Azure Blob Storage signed URL, so artifact ingestion no longer fails with `400 MissingRequiredHeader` on Azure-hosted regions. Upload errors now include the storage provider's error code alongside the status code. (#N/A)
- Require `sqlparse>=0.5.5,<0.7.0`, `sqlparse` 0.6.0 is the fixed release for CVE-2026-54284, CVE-2026-59893, CVE-2026-59894 and CVE-2026-71491 (parser denial-of-service). (#15988)
