May 1, 2026Summary for 2026-05: Delivered the Usage Metrics Throughput and Reliability Enhancement in harness/harness. This feature increases the buffer channel size and adds a queue size configuration, enabling the system to process a higher volume of usage metrics without drops. Mediator and Config were updated to handle larger metric volumes, resulting in improved throughput and reliability under peak load. No major bugs fixed this month; primary effort was feature delivery with internal refinements (e.g., removal of an extra go routine and unit-test tweaks as part of code-5313 commit). The changes reduce the risk of data loss and strengthen observability for customers.

Oct 1, 2024Delivered Go Modules Support for harness/harness by introducing HTTP middleware that serves go-import and go-source meta tags to enable Go module fetching directly from the repository. This feature integrates with the Git router and is associated with code-2461 (commit fdb41b5b384ab41a06ca674fbf7de47fe315e2dc). The work improves module resolution reliability for external consumers and positions the repository as a first-class Go module source.
