Sep 1, 2025

September 2025 monthly summary for yaklang/yaklang focusing on business value and technical achievements. This period delivered multiple high-impact features, critical stability fixes, and platform security improvements that collectively enhanced automated security analysis, developer productivity, and product reliability across the codebase.

August 2025

14 Commits • 6 Features

Aug 1, 2025

August 2025 focused on strengthening observability, robustness, and security reporting for yaklang/yaklang. Key outcomes include faster test cycles through threshold optimizations and memory-efficient tracing for MITM plugin execution, hardened SSA with nil-panics handling, variadic binding support, index protections, and reduced false positives in OrType member access. We also delivered advanced SSA reporting with new ECharts-based visuals, richer project/risk data structures, and improved formatting/URL handling. IRify reporting was modernized with a new report format and a revamped saving mechanism, integrating SSA results into a new IRify database schema. Security reporting was enhanced with CWE data and Mutual TLS (GM-TLS) support, updating certificate generation and TLS configuration. Overall, these changes improve reliability, reduce debugging time, and strengthen security posture, enabling faster feedback loops and better risk visibility for complex deployments.

May 1, 2025

May 2025 (2025-05) monthly summary for yaklang/yaklang. Key progress centered on strengthening the JS2SSA pipeline, expanding cryptography support, and enhancing SSA builder capabilities. Major deliverables include a comprehensive JavaScript to SSA conversion and parsing overhaul with support for classes, methods, control flow (if-else, loops, switch), improved type inference, error handling, and generation of control flow graphs; integration of a new parser/builder; initialization fixes; and test stabilization. Crypto library expanded TLS utilities to support base64-encoded DER and PEM RSA keys, with new parsing helpers and refactored encryption/decryption. Yaklang SSA builder added labeled break/continue support for precise control flow in nested constructs. In addition, test stabilization and init fixes reduced flaky tests and improved reliability. Business value: stronger static analysis, broader interoperability, and reduced maintenance overhead.
