February 2026 performance and delivery highlights for ClickHouse/clickhouse-cs. Focused on expanding data-type support in the .NET driver and strengthening CI/testing to improve reliability, onboarding, and alignment with modern runtimes (NET 6+).

January 2026: Delivered a focused set of features and reliability improvements for ClickHouse/clickhouse-cs, strengthening observability, connectivity, and test quality while expanding JSON capabilities. Key features include an ASP.NET health checks example to simplify health monitoring; PingAsync on ClickHouseConnection to improve connectivity checks and responsiveness; mid-stream exception detection via the X-ClickHouse-Exception-Tag header for earlier error visibility; and JSON handling enhancements enabling binary JSON writing and POCO-based serialization with configurable JsonReadMode/JsonWriteMode. In testing, framework improvements and a broader test matrix (including 25.12) substantially increased coverage and stability. Targeted bug fixes reduced noise and improved CI reliability. Overall, these efforts enhance customer confidence in .NET workloads using ClickHouse and demonstrate strong ownership of code quality and developer experience.

Month: 2025-12 highlights across ClickHouse C# client and docs focusing on business value, security, performance, and developer experience. Delivered geometry and data-type IO enhancements, authentication and authorization improvements, asynchronous workflows and benchmarking support, and documentation and quality-of-life improvements. These efforts enable customers to store complex spatial data, secure connections with roles and JWT, run asynchronous data pipelines with validated benchmarks, and onboard faster through clearer docs and examples. Also improved test stability and CI efficiency to reduce release risk.

November 2025 focused on reliability, cross-platform readiness, and release acceleration for the ClickHouse .NET ecosystem. Key features delivered included fixing a tuple parsing bug and expanding unit test coverage for enum/tuple parsing; enhancing cloud tests and CI across Windows/Linux/Mac; advancing enum/type handling; tightening API surface and improving release workflows and NuGet packaging; and expanding client logging and documentation to support .NET 10. Major bugs fixed spanned connection string handling, Windows test coverage gaps, WSL-related issues, ARM test stability, and logging/web request issues. The combined effort delivered safer production deployments, shorter feedback cycles, improved cross-platform support, and a stronger developer experience through better diagnostics and automated release processes. Technologies demonstrated include C#, .NET 10 compatibility, cloud/CI automation, NuGet signing and release pipelines, performance-focused test tuning (floating point tolerance), and comprehensive documentation and logging practices.
