Detailed changelog

​

Website

• Launched a new public marketing site at gumnut.ai, with Home, Platform, Enterprise, About, and Contact pages.

​

Apps

• Applied the Gumnut design system to the web app, including a new dark mode.
• Added a new Gumnut-hosted /sign-up route alongside the branded sign-in page.
• Added album management in the web app: create, rename, edit description, and delete.
• Added people management in the web app: rename, merge, and set a featured face.
• Added single- and multi-asset download.
• Added a move-to-trash action, a delete-face action, and the ability to draw a box in the viewer to create a face.
• Added “set as album cover” and “remove from album” viewer actions, and showed which albums an asset belongs to in the info panel.
• Parallelized uploads with an ETA and an add-to-album step after upload.
• Made the web app mobile-friendly: a nav drawer, smaller phone thumbnails, a responsive info panel, an icon-collapsing multi-select action bar, and touch-swipe navigation in the viewer.
• Paginated asset counts so the timeline scrolls past 200 months.

​

Video

• Added video playback to the web asset viewer, with the video filling the column like an image and Space toggling play/pause.
• Rendered video thumbnails in the timeline, viewer, web grid tiles (with a duration badge and hover preview), and the MCP app grid.
• Tone-mapped HDR (HLG/PQ) video thumbnails to SDR.
• Extracted make, model, and date-time from Samsung video tags.
• Fixed black-frame flashes, poster letterbox pop, and duration-badge clipping when paging to videos, and stopped a mouse swipe from starting playback.

​

MCP

• Added a view_asset tool that returns a photo’s pixels to the model so it can read text in or analyze the image.
• Added a save_asset tool for ingesting new photos and videos into a library.
• Rendered video thumbnails in the MCP app grid, added swipe navigation, and matched the viewer chrome to the web app on small screens.
• Fixed MCP tool calls being counted twice against rate limits.

​

Faces

• Added a SCRFD face-detection backend and made it the default detector.
• Added a create_face endpoint (and web UI) for manually drawing face boxes, and the ability to delete a face.
• Exposed face confidence and source in the API.
• Improved RetinaFace recall and backfilled previously missed faces.

​

Timezones

• Added user home-timezone handling so photos without embedded timezone information get a sensible local time — inferred from device neighbors, a timezone hint sent by the app, or a home zone derived from a user’s other photos.
• Cleared false UTC offsets from captures that lack offset information.

​

Immich compatibility

• Passed ThumbHash placeholders through to Immich clients.
• Exposed real storage quota to Immich and remapped over-quota responses from 507 to 400.
• Implemented POST /api/faces (manual face creation) in the adapter.
• Fixed a 500 on GET /api/albums for albums with naive start/end dates.
• Isolated the refreshed JWT per request as a safeguard against a theoretical cross-user leak.

​

API & SDK

• Added an include=variants token so asset reads return only the requested image variants, keeping default responses lean.
• Added single-asset streaming download via a Content-Disposition attachment.
• Published TypeScript SDK 0.108.0–0.125.0 and Python SDK 0.103.0–0.119.1 tracking these API changes.

​

Documentation

• Documented manual face boxes, lean asset responses and the variants token, MCP tool-call rate limits, asset capture-time handling, and original-asset download behavior.
• Pointed Immich setup docs at immich.gumnut.ai and refreshed the docs brand mark and favicon.

​

Apps

• Launched the new Gumnut web app at app.gumnut.ai, a Vite + React single-page app that replaces the previous web client.
• Added a virtualized photo timeline with justified rows, per-month data loading, date grouping, and a jump scrubber on both web and mobile.
• Added an asset viewer with EXIF metadata and prev/next navigation scoped to albums and people.
• Added albums, people, search, uploads (with per-image upload progress thumbnails), and API key management.
• Extended the virtualized timeline to the album and person views and migrated search to a justified, virtualized grid — all with infinite scroll, replacing the previous “Load more” buttons.
• Added a dedicated sign-in page for signed-out visitors, an Immich settings page linking to the Immich web and mobile apps, and an MCP setup page on the Chat tab for connecting Gumnut to Claude or ChatGPT.
• Retired the legacy Next.js web client, completing the move to the new app.
• Fixed the home page loading slowly on large libraries by paginating the timeline instead of fetching the entire asset list.
• Fixed asset search on Android.

​

Video

• Added basic video support: thumbnail generation, width/height and duration extraction at ingest, and a database schema for video metadata.
• Added streaming video playback through the CDN, including HTTP range request support for seeking.
• Surfaced video thumbnails and duration through the Immich adapter, and backfilled thumbnails, dimensions, and duration for existing videos.

​

Faces

• Switched face clustering to a graph-based approach (HNSW + Chinese Whispers).
• Added crowd-face filtering to keep large background crowds from polluting clusters.
• Shipped a self-service face cleanup dashboard for reviewing and triaging clusters, including an unassigned-faces tab.
• Began migrating face embeddings from FaceNet512 to ArcFace, with dual-write ingestion and new embedding/centroid storage.

​

Immich compatibility

• Added map markers and enabled the map feature flag.
• Added a read-only “On this day” memories endpoint.
• Added user edits to asset metadata (description, date/time and timezone, and GPS), wired through to single- and bulk-asset edit endpoints.
• Added Immich-compatible trash (soft-delete) with retention, honored across REST, sync stream, timeline, statistics, and WebSocket events.
• Served a sharper thumbnail size (small/720) for wide and panoramic photos in Immich clients.

​

Library management

• Added library trash/restore with an async purge window and SDK support.

​

API & SDK

• Added a POST /api/assets/bulk-update endpoint.
• Added a single-asset PATCH /api/assets/{asset_id} endpoint.
• Added image variant sizing improvements (a new small=720 rung and larger thumbnails) and ThumbHash placeholders for faster perceived loading.
• Moved the /api-keys router under the /api prefix and tracked API key usage via last_used_at.
• Fixed semantic search returning the same asset multiple times by de-duplicating stored embeddings, adding a uniqueness constraint, and making embedding writes idempotent.

​

Location

• Added reverse geocoding: selected a provider and added a backfill task that populates human-readable place names and location metadata.
• Added display_label and place_name to the asset metadata response.
• Introduced layered asset metadata (file, reverse-geo, and user layers) with rename cascade support.

​

Faces

• Added density-aware gates that reject loose clusters at creation and during per-asset assignment.
• Added density-aware auto-merge and auto-dissolve of unnamed people on reuse.
• Added clustering debounce and re-clustering of unnamed people, plus face quality filtering.

​

Immich compatibility

• Added a People merge endpoint and a PUT /api/people/{id}/reassign endpoint.
• Implemented GET /api/faces in the Immich adapter.
• Added the trash (soft-delete) backend, schema, and filtering.

• Added an Immich compatibility documentation section.

​

CDN

• Completed the CDN migration end-to-end, including Immich adapter asset fetching and migration cleanup.

​

Image descriptions

• Added a backfill mechanism to generate descriptions for existing assets.
• Added Google Gemini video descriptions, alongside the image description providers.

​

MCP & ChatGPT app

• Improved MCP app single-entity and zoom views, added a “Load more” button to album and person detail views, and adjusted thumbnail sizing.
• Audited and rewrote MCP tool descriptions for LLM consumption and added MCP tool annotations (readOnlyHint, destructiveHint, and others).
• Began the ChatGPT app submission: published the privacy policy, exposed merge_people as an MCP tool, and set up a demo account with sample data.

​

​

API

• Added batch ID filtering (ids) to list endpoints for bulk viewing.
• Added album_assets list and get endpoints with ID filtering.
• Added date-range filtering to the assets list endpoint.

​

Sync & events

• Designed and implemented first-class modeling of events and replaced the v1 events API with a v2 implementation.
