 ## 1.0.0
 
-Bundled with Termix 2.9.0.
+First release, bundled with Termix 2.9.0.
 
-- Homepage and the dashboard's service links moved out of core's own
-  servers on ports 30006 (dashboard) and 30012 (homepage), and now serve
-  under `/plugin-api/homepage`.
-- Owns its data: core's `homepage_items`, `homepage_layouts` and
-  `dashboard_service_links` tables are renamed to `p_homepage_*` on first
-  activation.
-- The favicon, RSS, ping and custom-API outbound requests now go through
-  `ctx.fetch` instead of a raw fetch, keeping the same SSRF guard.
-- New `homepage.use` permission, given to the admin and user roles.
-- Offers `homepage.items` v1 to other plugins; the AI assistant reads it
-  optionally.
-- The dashboard's "Dashboard / Homepage" toggle is now a contribution to
-  core's generic `dashboard.secondaryView` slot rather than a hardcoded
-  homepage case.
-- Core's uptime, recent-activity and database-health routes stayed on the
-  main server, now under `/dashboard` rather than a dedicated port.
+Adds a custom page of widgets, like clocks, notes, host status, RSS feeds and an embedded terminal. Also adds service link buttons to the dashboard.
