The batch EXIF stripper got a small optimization. Before processing each file, it checks whether metadata is actually present. If a photo is already clean — maybe you stripped it last week, or it came from a phone that never wrote GPS — it skips straight to the next one.
This matters more than it sounds. A lot of people dump mixed folders into the batch tool: some raw camera exports, some screenshots, some already-processed product shots. Previously it spent cycles rewriting files that had nothing to strip. Now it just moves past them.
The speed gain on mixed batches is modest but noticeable. More importantly, it cuts down on unnecessary writes, which means less wear on disks and fewer chances for a corrupted temp file to ruin a good batch.
