chore(release): 2.4.0

feat(core,fuse,gui): find photos that look alike
The duplicate finder gains an Exact / Similar switch. Similar asks the daemon for PhotoSimilar, which starts a background pass that hashes the thumbnail of every shot not hashed yet and replies at once with the sets found so far and how far hashing has got. The dialog shows a progress bar and asks again until the pass is done, then lists the sets. The pass takes thumbnails from the server only: a photo without one is skipped for the run instead of downloaded whole, and the dialog says how many photos could not be compared. Decoding and hashing are spread over the machine's cores. Every similar photo starts ticked Keep, since photos that look alike can be different shots. A similar photo stands for its whole shot, so one not kept goes to Trash with the rest of its shot.

 - **File Version History**: Every revision Proton Drive still holds for a file, from the browser's details pane (**Versions**) or `pdfs versions list|restore|save|rm`. Restoring is server-side — no re-upload — and an old version can be written out to a local file without touching the live one.
 - **Photo Favourites**: Star a photo in the lightbox, filter the gallery to favourites, or use `pdfs favorite <uid>` / `pdfs photos --favorites`.

Towns are looked up offline in [GeoNames](https://www.geonames.org/) data (CC BY 4.0), and the map is drawn offline from [Natural Earth](https://www.naturalearthdata.com/) land outlines (public domain), so no map tiles are fetched; install `iso-codes` for country names in your language.

Towns are looked up offline in [GeoNames](https://www.geonames.org/) data (CC BY 4.0), and the map is drawn offline from [Natural Earth](https://www.naturalearthdata.com/) land outlines and country borders (public domain). Each town is marked with one of its photos, and zoomed in, every photo sits where it was taken. A street map from [OpenFreeMap](https://openfreemap.org/) (© [OpenStreetMap](https://www.openstreetmap.org/copyright) contributors) can be turned on under Appearance; it is off by default because the tile server learns which parts of the world you look at.

 ## [Unreleased]
 ## [2.4.0] — 2026-09-28
 Schema: **34**. Photos gain a `similar_hash` column for the similar-photo finder. It stays
 empty until the finder is first opened, so updating reads and downloads nothing.
 ### Added
 - **Similar photos.** The duplicate finder gains a Similar switch that also finds resized or
  re-encoded copies and shots of one moment, by comparing the thumbnails. The first search
  hashes every thumbnail the server has, with a progress bar; photos without one are not
  downloaded and are counted as not compared. Every photo in a set starts ticked Keep, since
  photos that look alike can be different shots, and a photo not kept goes to Trash with the
  rest of its shot.
 - **Photos on the map.** Every town is marked with one of its photos and a count, and nearby
  towns merge into one marker until you zoom in. Zoomed in on a town, each photo gets its own
  marker where it was taken; clicking one opens it in the viewer, and clicking photos taken
  on one spot lists them all. "Show on map" in the photo viewer now goes to that spot on the
  Places map instead of a web browser.
 - **Street map for Places.** An opt-in setting under Appearance draws the map from
  [OpenFreeMap](https://openfreemap.org/) (OpenStreetMap data), with streets, water, parks and
  town names in your language. It is off by default because the tile server learns which parts
  of the world you look at. Tiles are cached under the cache directory (at most 256 MB), and
  the built-in outline shows wherever they haven't loaded.
 - **Proton theme.** The "Proton purple accent" preference is now a whole Proton theme: the
  Proton web apps' light and dark colours, not just the accent. It also holds when `gtk.css`
  imports another GTK theme (Catppuccin, Fluent, ...), whose own colours used to show through
  almost everywhere. Folders get Proton's purple folder icon rather than the icon theme's.
  Anyone who had the accent turned on gets the theme.
 - **Country borders on the Places map.** The offline map draws country borders, with sea and
  land in their own colours.

nvrl	a90eeecda9	feat(core,fuse,gui): find photos that look alike The duplicate finder gains an Exact / Similar switch. Similar asks the daemon for PhotoSimilar, which starts a background pass that hashes the thumbnail of every shot not hashed yet and replies at once with the sets found so far and how far hashing has got. The dialog shows a progress bar and asks again until the pass is done, then lists the sets. The pass takes thumbnails from the server only: a photo without one is skipped for the run instead of downloaded whole, and the dialog says how many photos could not be compared. Decoding and hashing are spread over the machine's cores. Every similar photo starts ticked Keep, since photos that look alike can be different shots. A similar photo stands for its whole shot, so one not kept goes to Trash with the rest of its shot.	2026-09-28 09:16:54 +02:00

Sets made only of byte-identical copies are left to the duplicate finder. A refresh keeps a hash unless the photo's bytes changed. The daemon pass, the control request and the GUI are not built yet; see PLAN.md.	2026-09-28 09:16:54 +02:00
