Immich 3.0 ships workflows, mobile editing, and breaking API changes

Category: Dev tools
Status: confirmed
Sources: Immich 3.0 discussion, release notes, HN discussion
Summary: The self-hosted photo platform Immich released 3.0 on 2026-07-02 (patch 3.0.1 same day). It adds a drag-and-drop Workflows automation builder (preview), mobile non-destructive editing, a Recently Added view, HLS and real-time video transcoding (preview, web), mobile OCR, and integrity checks for untracked, missing, and checksum-mismatched files. Breaking changes affect API integrators: pgvecto.rs support is dropped, deprecated environment variables and old timeline sync endpoints are removed, durations move to milliseconds, and the error and validation schema is restructured.
Why it matters: Self-hosters upgrading across the v2-to-v3 boundary must complete the vectorchord migration first (from before v1.133.0) and update any third-party tooling built on the changed API.
Follow-up: Track workflow and HLS transcoding moving out of preview and third-party client updates for the new API schema.
