October 2025 – espressif/arduino-esp32: VFS reliability improvement and production stability. Delivered a targeted fix to the Virtual File System by hardening stat() initialization and error handling. This change ensures buffering is only initialized after a successful stat() call and logs an error if stat() fails, improving robustness of file operations. Impact: more reliable VFS behavior across ESP32 projects, reduced edge-case failures, and improved observability. Implementation details: commit 34d9855291c0f51a171cb4a7d50b1320aa77f11f (fix(vfs): fix stat initialization, close #11908 (#11911)).
