February 2026 monthly summary for the typescript-eslint/typescript-eslint repository focused on a targeted bug fix that enhances TypeScript integration with ESLint. Key issue addressed: ESLint rule no-useless-default-assignments did not correctly handle the TypeScript 'this' parameter, affecting type-check accuracy and rule reliability. The fix adjusts parameter/index handling to align ESTree nodes with TypeScript AST representations, improving type checking and reducing edge-case misclassifications.

December 2025: Delivered HTTP/2 Cleartext (h2c) support over Unix domain sockets in the nodejs/undici client, expanding non-HTTPS intra-service communication options and improving deployment flexibility. Implemented validation for the useH2c parameter, added targeted tests including a case for invalid useH2c, and adjusted Windows CI to disable Unix socket tests for compatibility. This work broadens internal service communication patterns while maintaining CI stability and test coverage.
