What changed in API Change Watch.

Material product, methodology and dataset updates are recorded here. Provider events live in the event timeline.

Coverage expansion and event feeds

Expanded to 11 providers with platform-scoped source records. Product updates, action notices and explicit deadlines are distinct. Conflicting Bailian notices remain pending review. Automatic monitoring and delivery are still OFF.

English / Simplified Chinese option added

Added complete /zh static routes, a navigation language switch, Chinese event presentation translations, localized countdowns and filters, plus canonical, hreflang and sitemap routes for both languages.

Local MVP established

Added the public dashboard, event timeline and filters, provider pages, event detail, upcoming deadlines, alert preview, methodology, privacy, disclaimer, SEO metadata, static API feed and source-verified initial records.

Announcement and diff records separated

Introduced distinct source kinds for official announcements and detected page differences, plus verification state, last-checked timestamp and migration action.

Developer API focus set

Coverage is limited to model and developer API lifecycle changes. Consumer subscription plans are intentionally excluded from the product core.
