1.3.0 — 2026-06-14
Features
- GIF palette export — new Electron-only separation mode for reduced-color single-file GIF output; remaps SVG fills into a limited palette before rasterizing, includes a dedicated GIF icon, configurable color count and dither, and saves files with a
--{n}-colors.gifsuffix - WebP export — new primary export format in the main export modal; supports standard raster export flows with PNG fallback for mobile sharing
Other improvements
- Desktop page copy — Tessera for Desktop and supporting docs now call out GIF palette export alongside the other desktop-only features
1.2.1 — 2026-06-08
Bug fixes
- Desktop export filenames — exports now use the native system save dialog, and desktop image sources opened from the File Browser or other local ingest paths preserve the original image filename instead of falling back to timestamps or thumbnail-cache names
- Unsplash latest feed — the Latest view now follows Unsplash’s documented pagination headers when deciding whether more pages exist, restoring reliable infinite scroll when the API returns a short page before the end of the feed
