Prerelease: no

Release notes:

Added

• Enable Vector data type tests on Azure SQL Database #2762

What was added: Vector data type tests are now enabled to run against Azure SQL Database. Who benefits: Developers testing VECTOR functionality in Azure SQL DB environments. Impact: Ensures VECTOR data type support test coverage.

• Enable JSON data type tests on Azure SQL Database #2756

What was added: JSON data type tests are now enabled to run against Azure SQL Database. Who benefits: Developers testing JSON functionality in Azure SQL DB environments. Impact: Ensures JSON data type support test coverage.

Changed

• Revert function/procedure filtering via sys.all_objects #2751

What changed: Reverted #2705 change that used sys.all_objects for filtering. Restores previous behavior to maintain consistency across metadata APIs. Who benefits: Developers using getProcedures() and getFunctions() in JDBC. Impact: Preserves compatibility with numbered procedures and avoids discrepancies between APIs.

Fixed issues

• Address a hostname validation vulnerability by securely parsing certificate common names. #2801

What was fixed: Secure hostname validation is enforced by replacing the vulnerable CN parsing logic in SQLServerCertificateUtils.java, preventing spoofing attacks. Who benefits: All users of the SQL Server JDBC driver, especially those relying on TLS for secure connections, benefit from improved certificate validation. Impact: This fix closes a security gap, protecting applications from man-in-the-middle attacks and ensuring compliance with security best practices.

• JDK 8 compatibility for vector datatype handling #2750

What was fixed: Ensured fallback to JVM system property javax.net.ssl.trustStoreType if connection property is unset. Who benefits: Users configuring SSL via system properties. Impact: Enables proper SSL trust store resolution, improving compatibility with system configurations.

• PreparedStatement getGeneratedKeys() failure with triggers #2742

What was fixed: Fixed error "The statement must be executed before any results can be obtained" when using insert triggers with generated keys. Who benefits: Developers retrieving generated keys from inserts with triggers. Impact: Restores correct behavior for both update count accuracy and generated keys retrieval in trigger scenarios.

• Byte Buddy dependency scope #2755

What was fixed: Corrected Byte Buddy (1.15.11) dependency scope to test instead of compile. Who benefits: Developers and users of runtime artifacts. Impact: Reduces runtime artifact size (~8 MB) and ensures Byte Buddy is only included for unit tests.

• DatabaseMetaData.getIndexInfo() NON_UNIQUE value inconsistency #2773

What was fixed: Fixed incorrect NON_UNIQUE values due to mismatched handling of sp_statistics and sys.indexes. Who benefits: Applications depending on accurate index metadata. Impact: Provides consistent value of NON_UNIQUE field across SQL Server and Azure Synapse Analytics.

• DatabaseMetaData.getIndexInfo() invalid cursor position exception 2763

What was fixed: Fixed SQLException: Invalid cursor position caused when calling ResultSet.next() after exhaustion due to CachedRowSet strict cursor validation. Who benefits: Developers consuming metadata via DatabaseMetaData.getIndexInfo() on SQL Server or Azure Synapse DW. Impact: Replaces CachedRowSet merging with a UNION ALL query, ensuring standard JDBC cursor behavior while maintaining columnstore index support.
