generated: '2026-09-17' method: searched source: https://www.meddra.org/news-and-events/news note: MedDRA does not publish an API changelog. What it publishes is a DICTIONARY release cadence - a new MedDRA version every March and September, English first and the translations a fortnight later - announced as dated news items and accompanied by a "What's New with MedDRA Version X" document. Because every API operation is parameterised by MedDRA version and language, the dictionary release IS the thing a consumer has to track; the API contract itself carries info.version "1" and has not been versioned in the published spec. Entries below are read verbatim from the MSSO news feed. scheme: api_contract: info.version "1" - unversioned in the published OpenAPI; no /v1 path prefix data: MedDRA dictionary version, currently 29.1, released twice a year (March and September) selected_by: lang / ver path and body parameters on nearly every operation current_version: dictionary: '29.1' released: '2026-09-01' api_contract: '1' entries: - version: 29.1 (all languages) date: '2026-09-14' type: data highlights: All translations of MedDRA 29.1 available for download; MedDRA Points to Consider Companion Document release 4.0. - version: 29.1 (English) date: '2026-09-01' type: data highlights: English MedDRA Version 29.1 available for download. - version: 30.0 (proposed) date: '2026-08-07' type: process highlights: Request for comments on MedDRA 30.0 Complex Change Proposals; reminder issued 2026-09-14. - version: 29.0 (all languages) date: '2026-03-16' type: data highlights: All translations of MedDRA 29.0 available for download. - version: 29.0 (English) date: '2026-03-04' type: data highlights: English MedDRA Version 29.0 available for download. - version: API programme date: '2026-04-14' type: api highlights: MedDRA API Survey issued to subscribers by the MSSO. evidence: - url: https://www.meddra.org/news-and-events/news status: 200 note: The site is an Angular SPA; the dated items above were read from its own content API at https://admin.meddra.org/api/nodes?bundle=article (HTTP 200, 172 articles).
