Summary

Added release notes for March 27, 2026 (Capacity Reservations expansion) and March 20, 2026 (ODBC driver v2.1.0.0 with security improvements).

Security assessment

The March 20, 2026 entry explicitly states the ODBC driver release 'includes security improvements to authentication flows, query processing, and transport security' and recommends upgrading 'as soon as possible.' This indicates the update addresses security vulnerabilities or weaknesses in previous versions, making it directly security-related.
