v2.4.1 only accepts VectorChord >=0.3 <0.6 and refused to start on the new PostgreSQL 17 cluster with VectorChord 1.1.1; from v2.5.0 the range is >=0.3 <2. v2.7.5 is the last 2.x release; the 3.x upgrade comes separately.
The import into immich-postgres-17 matched the old database table for table (assets, embeddings, faces, people, albums, migrations). On start immich builds its VectorChord indexes.
Imported once from the PostgreSQL 14 cluster, whose embeddings were converted to real[] and whose pgvecto.rs extension was dropped first (immich's manual migration). After the import the columns become vector(512) again under VectorChord 1.1.1 with pgvector 0.8.6. A logical import because CNPG can't upgrade in place from the bullseye-based pgvecto.rs image to the bookworm-based VectorChord one.
The database moves from PostgreSQL 14 with pgvecto.rs to a new PostgreSQL 17 cluster with VectorChord. Immich 3 no longer supports pgvecto.rs, and PostgreSQL 14 reaches end of life on 2026-11-12.
ingress-nginx is gone and every app is served by the Envoy Gateway. The certificates were created by cert-manager's ingress-shim and are owned by the Ingresses, so each app now declares its Certificate itself, with the same name, secret and usages, so nothing gets reissued. gateway-shim can't take over because the certificates live in the app namespaces.
immich drops mbg.hensen.io, which has no route, so that one certificate is reissued through the Gateway's HTTP-01 solver.
Also removes the Longhorn test-port redirect URI and updates comments that still described nginx.
Each app gets an HTTPS listener on the Gateway with its existing certificate, an HTTPRoute, and a ReferenceGrant for that certificate. The routes drop Envoy's 15s request timeout, as nginx has no overall limit either. Argo CD and Longhorn follow separately; the Ingresses stay until the switch-over.
Mount patched-ca-bundle (see ca-bundle/) over /etc/ssl/certs so it stops trusting the compromised eMudhra intermediates (https://emudhra.we-have-a-problem.com). The server gets --use-openssl-ca for Node, machine-learning points requests at the bundle instead of certifi.
