Documents the vector-default behavior changes: since v1.39.1 auto-schema creates a named vector called default (vectorizer none; DEFAULT_VECTORIZER_MODULE is not applied), and from v1.40 a collection definition with no vector parameters creates a genuinely vector-less collection instead of getting the implicit legacy index. Adds a migration note, rewrites the config-ref's now-false "single vector collections" description, adds a "create a collection without a vector" how-to section, and states the client caveat (Python ≥ 4.21.2; older clients still send vectorIndexType and are unaffected).

Grounded in a file:line CodeBrief at v1.40.0-rc.1; claims not verifiable there are not made.

* docs: v1.40 version bumps — release notes, compose pins, versions-config, release history

* docs: re-ground named-vector defaults at stable/v1.40 — DEFAULT_VECTORIZER_MODULE deprecated, mixed collections, default-alias scope

* docs: multi-vector embeddings on the HFresh index (v1.40) (#564)

* docs: v1.40 release review fixes

Correct the named-vector defaults and the DEFAULT_VECTOR_DISTANCE_METRIC scope, scope the multi-vector compression notes to the index type, fix the HFresh multi-vector reference, and refresh the patch versions and the release history C# column. Document PathSeer, the MCP hybrid changes, the backup-gcs transport default, weaviate_shards, the shards API per_node_status, read_backups, operator_metadata_reader, RQ centering, and the text2vec-google mutable settings. Add near-vector to the GraphQL migration guide and remove the temporary /deploy/enterprise redirect.

* ci(links): skip doi.org and dl.acm.org, which 403 automated requests

* docs: shorten the PathSeer concepts section and skip linkedin.com in link validation

Align the PathSeer section with the measured results: it wins or ties on random, topical and combined filters, and ACORN stays ahead on sparse negatively correlated filters. Drop the per-index details that belong in the reference. LinkedIn rate-limits the CI link validator with 429 on the footer link.

* docs: clarify the single vector collection caution

* docs: drop the redundant vector-less collection how-to section

* chore(specs): refresh the Weaviate OpenAPI spec to v1.40.0

Built from the v1.40.0 tag with the docs overlay. No paths or definitions were added or removed since 1.39.8. Changes land inside existing ones: read_backups in the permission enum, per_node_status on the shard status response with status and vectorQueueSize deprecated, dedupeReplicas and dedupeConvergenceTimeoutSeconds on the backup config, users and roles in the backup descriptions, license-key 403s on the namespaces endpoints, and the vectorizer empty-default wording. The overlay picks up the new collections link and the license-key sentence on the namespaces tag.

* docs: remove restated v1.40 facts, keep each in its canonical home

Deduplicate the DEFAULT_VECTORIZER_MODULE deprecation to the env-vars row and the migration section, shrink the vector-less collection reference, state the HFresh MUVERA requirement and search budgets once, shorten the 4-bit RQ, shards API, MCP hybrid and Meta provider additions, and correct the REST search request-body cap, which has returned 413 since v1.39.7.
