Changelog

What's new in X Sim Lab. Newer releases at the top.

v1.4.2 — June 2026

More cameras confirmed working, a refreshed recipe manager, and the new glass control set throughout the editor.

Glass-style controls across the editor, including a tuner dial for white-balance colour temperature
Your camera is recognised automatically on connect, so its film looks and controls match exactly what that body can do

Recipe manager refresh: changes commit when you save, a cleaner add-recipe dialog, and a read-only browsing mode
Camera support is more accurate body by body — film looks and fine-tuning steps are now right for each camera, not assumed

Cameras sitting on the Default film-sim position now connect reliably
Saving recipes and your camera library is more dependable, with clearer recovery if something goes wrong

Smoother connections for more camera bodies.

Previous-generation bodies (like the X-T30 II) now connect cleanly instead of being turned away
Late camera callbacks after unplugging no longer cause crashes
A camera that briefly drops its connection is no longer mistaken for an unsupported one

The recipe lab becomes its own workspace, recipes gain tags and search, and the iPad gets a proper home screen with settings and a camera library.

Recipe lab: a dedicated workspace with search, plus tags you can filter by
Name and tag recipes however you think, with suggestions from tags you already use
Setting sets: back up all seven custom slots from a body and swap recipes on top, then restore the whole set in one go
Paste in a recipe you find online and it becomes an editable entry
A home screen with settings and a My Cameras library — cameras add themselves on connect, or pick them from the list yourself
Read the full shot info (EXIF) for any frame, no camera needed
Your filmstrip stays put across app restarts
Friendly loading screen while a photo develops
New app icon

Your library lives in iCloud — a delete on one iPad no longer reappears on another, and older local recipes can be moved over with a tap
Smoother preview: better zoom, and crop authored right in the zoom view
The editor tells an untouched shot from an edited one at a glance

First round of field-tester fixes.

Camera import shows every thumbnail; portraits, 16:9, and square shots aren't cropped to landscape
Name a camera slot yourself when sending a recipe across
Frame mode opens fitted to screen — no more stuck blurry crop
Crop ratios stay accurate on any photo orientation
Switching photos while one is developing no longer lands the result on the wrong shot
Clearing the filmstrip returns to the empty state instead of freezing on the last photo

A stalled camera now recovers with a clear "disconnect and reconnect" message instead of hanging

First release on the App Store.

Connect your Fujifilm camera over USB-C and develop your RAWs with its own rendering
The full set of current Fujifilm film simulations and recipe settings
Crop your shots
Import from Files, from Photos, or straight from the camera
Save and manage your recipes
Work with your camera's seven custom slots (C1–C7)
Try different recipes on copies of the same shot
Reset any photo back to how it looked out of camera
Zoom and pan the preview
