  Who benefits: Developers building AI/ML workloads or semantic search applications using vector data in SQL Server.
  Impact: Enables native vector storage and access via JDBC, eliminating the performance overhead of managing vector data as strings.

• New connection options, quotedIdentifier and concatNullYieldsNull #2618
  What was added: New connection options, quotedIdentifier and concatNullYieldsNull, to control QUOTED_IDENTIFIER and CONCAT_NULL_YIELDS_NULL session settings for both new and pooled connections.

  Impact: Improves performance for previously unsupported types (except in Azure Synapse Analytics (formerly Azure SQL DW).

• Mockito integration into JDBC driver tests #2644
  What was added: Mockito added as a test dependency.
  Who benefits: Developers and contributors writing unit tests.
  Impact: Enables better control and test coverage.

Changed

• releaseSavepoint exception type standardized to SQLFeatureNotSupported #2583
  What changed: SQLServerException replaced with SQLFeatureNotSupportedException to comply with JDBC specification.

  Who benefits: Microsoft Entra ID authentication users.
  Impact: Encourages migration to more secure methods.

• Include Columnstore indexes in getIndexInfo() #2598
  What changed: Replaced sp_statistics with a custom query to support all index types.
  Who benefits: Developers using metadata APIs.
  Impact: More accurate index metadata.

  Who benefits: Users of metadata functions.
  Impact: Complies with JDBC specification and avoids confusion.

• Increased redirection limit #2659
  What changed: Raised maximum redirection hops from 1 to 10.
  Who benefits: Azure SQL Fabric users.
  Impact: Enables successful multi-hop connection scenarios.

Fixed issues

• Session recovery with Entra ID authentication and redirect mode #2668

  Who benefits: Reviewers using CodeQL.
  Impact: Maintains compatibility and audit clarity.

• Batch insert fix for case-sensitive column name mismatch #2695
  What was fixed: executeBatch() now respects case sensitivity of collations when matching column names.
  Who benefits: Applications using case-sensitive/case-insensitive schemas.
