THE FINDING IS THE GAP: the newest entry on the page is Blocks v24.1.1, dated 22 January 2024. Nine entries are published, all between November 2022 and January 2024, and nothing has been added in the two and a half years since, even though the platform has demonstrably moved on (the live member service reports version 2.10.1, the product has been rebranded to SIMBA Trace on the website, and first-party packages shipped as recently as June 2026). The changelog does not describe what is running. versioning: scheme: calendar release (Blocks vYY.N.P) header: none current_published_entry: v24.1.1 current_published_date: '2024-01-22' live_service_version: 2.10.1 live_service_version_source: https://blocks.simbachain.com/api/member-service/version (probed 2026-08-27) note: >- The Blocks vYY.N.P platform release number and the 2.10.1 member-service version are different counters; no page reconciles them. breaking_change_policy: published: false note: >- No deprecation or breaking-change policy is published.
