--- title: "Changelog" description: "Release notes for Open Negative Initiative, newest first; most say up front whether they change how a photograph you have already adjusted will render." url: "https://open-negative-initiative.com/changelog" date: "2026-11-03" --- # Changelog **Every version of Open Negative Initiative, newest first, with the note it shipped with.** When a note says whether a photo you have already adjusted renders differently, its line says so before you open it. - **Latest version**: 1.5.4, 2 November 2026 - **Download**: [For Mac](https://github.com/5e1y/open-negative-initiative-releases/releases/latest/download/OpenNegative.dmg) or [for Windows](https://github.com/5e1y/open-negative-initiative-releases/releases/latest/download/ONI-windows.zip), free - **Follow**: [The feed](https://open-negative-initiative.com/changelog.xml), or [every release on GitHub](https://github.com/5e1y/open-negative-initiative-releases/releases) ## 1.5.4 2 November 2026 **ONI 1.5, the slide film and contact sheet update.** - **The whole roll, once measured**: after Prepare the Roll, every frame shows together, numbered by its place on the film. - **Contact sheets**: select a few frames, or press the orange key for the whole roll, and they lie together on one sheet. - **Export a contact sheet**: the export panel exports the selection as one sheet, with a preview; the orange EXP. CONTACT SHEET key opens it. - **Slide films**: Prepare the Roll balances a slide roll on a white or grey you click, its colour alone; without a click, the slides keep the camera's 5500 K. - **Contact sheets on black**: every contact sheet, slides included, lies on black, numbered in orange; the logo shows under a full row of five. - **The whole scan in Prepare**: every scan is shown and measured uncropped. - **RESET SCAN keeps your crop**: everything goes back to rest but the framing and the conversion. - **Trash from the editor**: the next frame of the roll opens in its place. - **Select all beside a photo**: the folder's photos show together; a click on one shows it alone again. - **No more flicker on Windows**: clicking outside the window and back no longer blanks it for an instant. - **Large 16-bit TIFFs**: a 16-bit TIFF of 45 Mpx and more opens, in the editor and in Prepare the Roll. - **A scan that cannot be read says why**: Prepare the Roll no longer waits on it. - **Nikon High Efficiency RAW**: a click converts a folder’s HE and HE* NEF files to lossless DNGs through Adobe DNG Converter, which ONI downloads and installs when it is missing. - **One RAW decoder, the same colours everywhere**: a RAW opens in the same colours on Mac and Windows. The Mac's per-camera matching to the former Apple decoder is gone; photos you already edited keep their look through their Source Balance gains until their roll is measured again. - **Windows updates itself**: from 1.5.3 on, the app finds the next versions and installs them when you ask, as on the Mac; an older copy is updated once by hand. - **Compare on a contact sheet**: Compare Before/After splits the whole sheet, each frame shown on its own before. - **Every frame follows**: on frames shown together, switching to the Scanner face or choosing another proof redraws every frame, not the open one alone. - **Crop and De-dust wait for one frame**: a crop, a measuring window or a dust spot belongs to one photo, so they are greyed while frames show together. - **Take a frame out**: after Select All, a `⌘`-click (Ctrl-click on Windows) in the column takes a frame out of the group, and a second puts it back. - **The folded Library shows whole**: slid over the canvas, it no longer cuts its fields and stars at its edge. - **A quieter look**: the raised and sunken surfaces are half as deep, the histogram lies on the scanner screen's black, and the canvas is square where it meets the panel or a folded column.
