Jul 1, 2025

July 2025 monthly summary for Vector35/binaryninja-api focusing on KernelCache improvements and stability across the KernelCache/Mach-O/SharedCache stack. Delivered a controller-based KernelCache overhaul with an enhanced API surface for loading, querying, and managing cache data, plus updates to Python bindings and internal structures to improve usability and integration with imaging, symbols, and metadata workflows. Standardized and improved logging across related components to boost observability and maintainability, and tightened build configuration for consistent debug/release behavior. Fixed critical parsing and image-loading issues that caused reliability gaps and user-visible dialogs, and resolved GCC-related compile-time issues in SharedCache to improve cross-compiler portability. These changes collectively reduce time-to-insight for kernel cache data, increase stability of symbol loading flows, and simplify integration for downstream tooling and bindings.
