# Zipic V1.9.7

> Zipic v1.9.7 — brand-new in-house jxloptim engine delivers full-fidelity JXL HDR encoding and lossless AVIF ↔ JXL gain-map round-trip; redesigned Preset Manager, three-state output location, drop-to-preset onboarding, and mid-run stop. Plus fixes for iCloud monitoring, the daily free quota, CLI long-running tasks, re-compression quality, and full EXIF / XMP / ICC preservation across HEIC, PNG, JPEG, JXL, and AVIF.

Many of v1.9.7's fixes and new features trace back to real user feedback — special thanks to Adam, Shengrun, Fernando, Pipu, at0gjm, @_Octree, and everyone else who took the time to share. You're what keeps Zipic getting better. 🙌

## ✨ New Features

- **JXL HDR encoding**: brand-new in-house `jxloptim` engine — convert HDR images to JXL with full color fidelity preserved.
- **AVIF ↔ JXL gain-map round-trip**: HDR gain maps now travel losslessly between AVIF and JXL.
- **Redesigned Preset Manager**: the preset dialog is now tab-based — create, rename, and duplicate presets all in one panel.
- **Three-state output location**: original folder / ask every time / fixed folder — the choice is finally unambiguous.
- **Multi-preset drop onboarding**: the welcome window now shows the ⌥-drop shortcut for per-preset compression.
- **Stop compression mid-run**: cancel any running batch at any time without disturbing other tasks' progress.

## 🐛 Bug Fixes

- **iCloud & massive folder monitoring**: switched to event-driven monitoring — 100k-file libraries and iCloud subfolders no longer freeze.
- **Monitoring depth applies instantly**: changing the depth takes effect immediately, no need to toggle the monitor.
- **Free quota refresh**: the 25/day free quota works again after the trial ends; failed or skipped files no longer count.
- **Thumbnail priority**: thumbnail generation no longer stalls the main UI.
- **CLI long-running tasks**: streaming progress protocol — multi-hour jobs no longer report false failures, and concurrent runs stay isolated.
- **Re-compression on replace**: switching compression levels now restores from the backup first, so quality no longer degrades across rounds.
- **HEIC keeps full EXIF / XMP**: copyright fields and non-standard namespaces are preserved.
- **PNG keeps wide-gamut ICC**: Display P3, HLG and friends survive JXL / AVIF / HEIC → PNG conversion.
- **JPEG / PNG cross-format metadata**: EXIF, XMP, and ICC profiles are fully preserved.

## 🚀 Other Improvements

- **Massive-batch compression**: memory firmly contained — no more leaks; the UI stays responsive at tens of thousands of images.
