October 2025 performance note for JetBrains/kotlin: Delivered a targeted Kotlin/Native Zip File Accessor cacheability fix to address a performance regression in the compiler. When a cache limit is set, ZipFileSystemCacheableAccessor is now used, preventing the non-cacheable ZipFileSystemInPlaceAccessor from participating in caching paths. The change improves profiling accuracy and build performance for cache-sensitive workflows. Coordinated with a focused commit: d6d534728e43cf184ec9dea7c93e0e058aa5c2a0, 'Piping ZipFileSystemCacheableAccessor when cache limit is set to missing sections'.

September 2025: Focused on stabilizing Kotlin/Native build pipeline in google/kotlin by addressing linker robustness and early detection of ld errors. Implemented a separation of static and dynamic libraries in linker options, added dynamicLibraries to LinkerArguments, and ensured they are passed to the linker to prevent long-command-line ld errors. This work reduces build failures and improves reliability for Kotlin/Native projects. The change is complemented by a dedicated commit to create a dynamic_caches file to avoid ld issues.
