Complete Version history / Release notes / Changelog / What's New for Diffractor


Diffractor 1.27.2

Three dates, each labelled — Original, Created and Modified are now separate and searchable, so an edit no longer moves a photo to the day it was retouched (#184).
Panoramas and 360° photos — wide stitches sweep at full width, equirectangular files become a camera you turn by dragging, and @panorama finds them.
Items view settings without scrolling to the top — group, sort, media-type filter and Show items in subfolders open from the scroller (discussion #251).
The sidebar map is now a globe, and the history chart spans your whole collection (#175).
Verbose metadata reports what the file actually holds — unnamed tags kept, maker notes as directories, embedded thumbnail shown.
Security updates — expat 2.8.3 closes CVE-2026-72522, plus libopenmpt, libarchive, libebml and sqlite.
Before you upgrade: taken:, when:, timeline: and c: now mean Original, so saved searches may return different results. Every icon is redrawn.


Diffractor 1.27.1

Fixed a crash affecting some users on startup.
Uses much less memory while browsing and viewing.
Ratings and keywords cannot be lost to a locked sidecar — a .xmp that cannot be read is refused, not rebuilt from the edit alone.
Duplicate detection stops fading out — scrolling a video into view no longer clears its checksum.
Video plays in software rendering — with hardware acceleration off.


Diffractor 1.27.0

Improved UI, Zoom, rebuilt. Hold to peek at full detail, or press Ctrl+Space for a proper zoom mode that stays put while you pan, compare, and move through your photos. Pinch, drag, double-tap, wheel, or use the corner navigator — and the image sharpens as soon as you stop moving.
Search by where a photo was taken. Type a city, a state, a country, or just click the map, and photos with only GPS coordinates now answer too. Diffractor no longer confidently attaches the wrong town name to a photo — if it isn't sure, it says Near X with a direction instead.
Finds the same photo saved twice. A resized copy, a re-export, a re-save, or one you rotated is now recognised as a duplicate even though the file name, size, and checksum are all different. Crops stay separate, and burst sequences and scanned pages don't produce false matches.
Related items actually finds related items. It used to show duplicates only. Now it also shows photos from the same album, the same series, taken around the same time, and taken in the same place — each in its own group, closest first.
Rename, Import, and Sync are easier to use and safer. Each one now walks you through it, shows exactly what it is about to do to every file, and lets you decide what happens when a file already exists before anything is written. Copy and Move do this too, instead of quietly making a second copy.
Better photo editing. Fix converging verticals, warm or cool an image, and let Auto color, Auto straighten, and Auto document do the first pass for you. Auto document sets the same crop and straighten sliders you'd use yourself, so you can nudge or undo any part of it — and none of it freezes the window on a big RAW.
Faster, safer edits to your files. Rating a RAW file no longer copies the whole file to record one star. Writes to network drives, OneDrive, and files another program has open now either work or tell you why they didn't, and never leave stray temporary files behind.
Now translated into 13 languages. Czech, German, Spanish, French, Italian, Japanese, Korean, Polish, Portuguese, Russian, Turkish, Ukrainian, and Chinese.
Multiple bugs fixed:
#189 — mixed text sizes after changing the font size
#232 — a missing Calibri font flooded the log file
#103 — OneDrive reverted ratings and tags after syncing
#207 — writes to network drives failed and left temporary files
#180 — tagging a file another program had open froze Diffractor
#78 — videos displayed with the wrong aspect ratio
#61 — video locations never appeared on the map
#219 — Korean tags failed to display, add, or search
#184 — photos sorted by edit date instead of capture date
#215 — Explorer opened every folder in Diffractor

This release adds new features to make it easier to manage a large collection of photos and videos. It allows you to easily determine if an item is in your collection or not. All indexed locations combined make the collection.

The changes are:

Allow grouping items by presence. Did you ever insert an old memory card and wonder do I have these photos on my hard disk? Now you can open diffractor and sort those items by presence in your collection. Items not in your collection will be grouped together.

Fixed a crash when decoding truncated TIFF files.
Fixed a crash when decoding malformed GIF files.


Diffractor 122.8 2020-07-05

This release adds an ‘Ignore previously imported items’ option to the import/structured copy dialog.

As with 122.7, in this release there has been a rationalization of keyboard accelerators. The biggest difference is a change in how SPACE and ENTER are used. SPACE now stops and starts video playback or slideshows. Enter opens items and toggles media full-screen. This makes Diffractor like most other Media software. Hopefully helps the transition for users between software products.

This release also includes a new Keyboard reference screen (control-F1) where accelerators can be reviewed.
