-- **One entry per feature**, not per commit — the shipped state, with its in-cycle fixes folded in.
+- **One entry per theme**, not per commit or per feature — the shipped state, with its in-cycle fixes folded in.
 - **One line per entry**, no explanatory paragraphs: `Prefix: **bold lead** — terse clause naming what was done.` Skip the failure-mode/root-cause narrative even on fixes. The long multi-sentence bullets in old sections are **not** the target.
 - Prefix each with `New:` / `Change:` / `Fix:` (use `Change/Fix:` if genuinely both). Group in that order.
 - **No PR/issue numbers** (`(#604)`) — user-facing notes, not a dev index.
 - US **"color"** in prose, matching the UI labels (Color Negative, colour spellings were swept out in 0.50.0).
 - Plain, factual, non-salesy — it's an open-source project. No marketing framing, no dunking on other tools.

 NegPy turns scans of film negatives and slides into finished pictures. I wrote it because I wanted a tool made for film scans that does more than invert them. It models film and photographic paper, and adds the conveniences of a lab scanner. It is written in Python and runs on Linux, macOS and Windows.

 # Change Log
 
+## 0.64.0
+
+- New: **Expanded Analysis** — Waveform and Vectorscope views beside the Curve chart, a Clipping Overlay, zone strip hover that highlights the zone's pixels, a double-click on the zone strip toggles the Zone Overlay, and the step wedge prints through alt process and toning.
+- New: **Darkroom printing** — Sabattier as a third Alternative Process (Strength, Re-exposure, Agitation for the Mackie lines), Local Flash on a Dodge & Burn mask, and a Diffusion slider on the Tone card. @jondestoppeleire
+- New: **Auto Grade Shadow Hold** — lifts shadows on contrasty frames, and Auto Density and Auto Grade show their values on the sliders.
+- New: **Camera scanning** — live view histogram and clipping zebras, Meter sets the shutter from one RAW probe, single-capture narrowband scanning that saves a sensor profile, a profile captured straight from the tethered camera, a Method choice for the sensor calibration against blown blues, and a New Roll button. @jondestoppeleire @seanharding @thetalkingdrum
+- New: **Check Flat Field** — shows how even a flat field is from any frame, and saving warns when the reference is clipped or uneven. @thetalkingdrum
+- New: **Export** — a Sharpening slider that runs at the final size after a resize, and White Paper and Film Base options that print the contact sheet with less ink. @seanharding @jondestoppeleire
+- New: **Workflow** — Paste to every selected frame, Copy Card Settings, Undo Apply to Roll, Unmarked Only and Advance After Marking for triage, Load Edit from Sidecar…, a 1:1.4142 (ISO A) ratio, and a Color vision setting in Preferences → Accessibility.
+- New: **Catalogs** — every current film stock under Kodak's 2026 names, Hasselblad V, Nikonos and Nikon AF gear, five more crosstalk matrices, and Panasonic RW2 embedded lens correction. @jondestoppeleire @red-prs
+- Change: **Auto Crop** — a roll setting on the Crop card with Frame/Roll scope, mirrored on Geometry; Roll asks before a push changes it for other frames, hand-drawn crops stay out of it, and Square Before Crop runs the Auto Skew fit first. @kurtwindisch @jondestoppeleire
+- Change: **Interface pass** — a canvas toolbar with zoom, Print and Overlays menus and a tool row while a tool is armed; segmented choices, Paper Response as its own card, panels that compact instead of clipping, and tooltips on every control.
+- Fix: **Export safety** — an export never overwrites its source or another frame, unedited and border-crushed frames are flagged, and one failed file no longer stops a batch. @jondestoppeleire
+- Fix: **Sidecars** — edits restore reliably from .negpy sidecars in the Film Strip and batch export, and a fork's or composite's edit stays out of the shared sidecar.
+- Fix: **Flat Field and peeks** — the gain follows each frame's orientation, half frames take their own half, Auto Crop and Roll Analysis read the flat-fielded source, and an edit, frame change or rotation closes every peek. @thetalkingdrum
+- Fix: **GPU and CPU match** — border color, tiled paper white, warped-crop metering, Hue Trim on slides, split-toning masks, Chroma Denoise tiles and slide Shadow Reach on export; Dodge & Burn grays out on slides.
+- Fix: **Scanning** — Coolscan single-frame adapters, Output folder and file-pattern checks, a busy scanner on Meter Frame, typed Resolution without Enter, and film re-measured after a format change.
+- Fix: **File loading** — palette, MinIsWhite, CMYK, planar and two-sample gray TIFFs, LogLuv, CR3/RAF orientation, oversized TIFF and Nikon Scan thumbnails, and NegPy's own ICC profiles on reload.
+- Fix: **Editing** — brush and mask sizes against the whole frame, off-frame mask points kept, crop resets as undo steps, Crop Offset clamped, and forked frames and renamed roll folders keep their edits.
+- Fix: **Library and canvas** — brush size kept from frame to frame, a sharp canvas after a screen change, roll counts show photos, dot-prefixed files are skipped, and Cast Removal holds on a mixed neutral set. @s6stkurz @jondestoppeleire @seanharding @perryd01
+- Fix: **Stability and speed** — quitting cancels running batches and exits cleanly, and library search, roll switching and GPU renders are faster.
+- Fix: **Nix flake builds with current nixpkgs.** @activexray
