[13.1.1] Preview Release

Added

• JSON datatype support #2558 What was added: Support for reading and writing JSON columns in SQL Server. Who benefits: Developers working with semi-structured data in SQL Server. Impact: Enhances application flexibility by natively handling JSON content, reducing need for manual parsing.

• Add order hints for Bulk Copy operations #2701 What was added: Support for specifying order hints during Bulk Copy. Who benefits: Data engineers and DBAs managing large data migrations or ETL jobs. Impact: Improves bulk data load performance.

• Coding best practices and review process #2666 What was added: Introduced contributor guidelines, coding best practices, and review processes. Who benefits: Open-source contributors and maintainers of the mssql-jdbc project. Impact: Improves code quality, consistency, and onboarding experience for new contributors.

Fixed issues

• Fix for null handling in temporal types with bulk copy #2702 What was fixed: Properly handle null values for temporal types when sendTemporalDataTypesAsStringForBulkCopy=false. Who benefits: Developers using batch insert with native temporal types in bulk copy. Impact: Prevents failures during bulk inserts, improving reliability of time-sensitive data ingestion.

• Fix string insertion with bulk copy API when sendStringParametersAsUnicode=false #2704 What was fixed: Resolved issue where strings were inserted as byte arrays in batch bulk copy mode when sendStringParametersAsUnicode is set to false. Who benefits: Developers using non-Unicode string inserts in performance-sensitive batch operations. Impact: Ensures string integrity during batch inserts, eliminating silent data corruption.

  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.
  Who benefits: Developers needing Sybase-default behavior for their applications.
