What exists instead is a set of one-off change notices embedded in the docs pages themselves — a "Recent changes" block on the Webhooks page and a standalone migration article — each carrying a real removal date but no date of publication. There is no RSS feed, no archive and no way to diff two points in time. The Productboard "product developments" portal covers planned work rather than shipped change. Recording the two published notices here; this is a genuine gap in Nedap's operational transparency, not an absence of change. entries: - version: null date: null effective_until: '2027-03-01' type: deprecation source: https://ons-api.nl/english/technical/Webhooks.html highlights: - >- CUSTOM webhook events now carry event-specific data under payload. Integrations should read custom identifiers from payload; the deprecated top-level custom-event id remains for backwards compatibility only until it is removed after 1 Mar 2027. - version: null date: null effective_until: '2026-05-19' type: breaking source: https://ons-api.nl/english/technical/API_migration_2025.html highlights: - >- Every endpoint path migrated from the /t/ prefix to /v0//. 877 endpoints remapped; 41 with parameter changes. Old endpoints removed 2026-05-19. - >- operationIds and OpenAPI parameter order deliberately held stable so generated clients migrate by swapping the input specification. additions: [] breaking: true missing: dated_changelog: true feed: true note: >- "New resources are added as they become available, without further notice" — the API properties page says so outright, which means additive change is undocumented by design and only removals are announced.
