It runs a public status page and a dated changelog, but publishes no deprecation policy, no sunset guarantees and no SLA — and it has shipped at least two field/response-shape removals in place on v3. versioning: scheme: uri-path current: v3 docs: https://developers.feedly.com/reference/introduction header_versioning: false date_versioning: false note: >- /v3 is the only version segment in every published OpenAPI servers[] block. There is no version header, no date-pinned version, and no published statement about how a future major version would be introduced or how long v3 would remain supported. deprecation: policy_url: null policy_published: false sunset_header: false deprecation_header: false rfc8594: false note: >- NO deprecation policy exists. Feedly publishes no notice period, no support window, and does not emit RFC 8594 Sunset or Deprecation headers. Changes are announced in the changelog only, with no dated removal schedule. A consumer's only warning mechanism is reading the changelog. deprecated_operations_in_spec: [] spec_note: >- Zero of the 49 published operations carry `deprecated: true`. Every spec that sets the flag sets it to false. The specs therefore give no machine-readable deprecation signal at all. observed_breaking_changes: - change: >- `attackVector` field REMOVED from POST /v3/trends/vulnerability-dashboard and replaced with `cvssVector` (standard CVSS notation). operation: getVulnerabilityAgent kind: field removal announced: https://developers.feedly.com/changelog/vulnerability-dashboard-api-attackvector-field-deprecated notice_period: none published note: >- The changelog title says "Deprecated" but the body says "Removed" — the field was taken out, not deprecated. Old values were NETWORK, LOCAL, ADJACENT_NETWORK, PHYSICAL. - change: >- `relationships` field REMOVED from the GET /v3/entities/{threatActorId} response; relationship data moved to GET /v3/ml/relationships/actor/{threatActorId}. operation: get-threat-actor-metadata kind: response-shape removal announced: https://developers.feedly.com/changelog/threat-actor-relationships-endpoint-updates notice_period: none published note: >- The original endpoint is "still supported" but silently returns less. A client reading `relationships` now gets nothing rather than an error — a silent failure mode. experimental_surfaces: note: >- Feedly labels some surfaces experimental/alpha in the docs, which is useful signal, but there is no stated graduation or removal process for them. items: - name: Custom Agents (GET /v3/dashboards, GET /v3/custom-agents/{id}) status: alpha warning: >- "Alpha: Custom Agents is a new capability and still under active development.
