May 2026 focused on strengthening observability for HTTP error handling in litestar. Delivered HTTP Exception Status Logging and Metrics Instrumentation: the Prometheus middleware and logging layer now accurately capture and log HTTP exception status codes, with dedicated error handling for common exceptions to ensure correct codes appear in both logs and metrics. Added tests to verify middleware behavior when exceptions occur, increasing reliability of observability. Code quality improvements included lint cleanup and removal of trailing whitespace. These changes enhance business value by enabling precise SLA reporting and faster incident triage through more reliable metrics and dashboards. Implementation anchored in commit 409abb2b0e7b5fde20aa56ddc624a1c736999d8c.
