+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [2.0.0] - 2026-02-27
+
+### Breaking Changes
+
+- **Core barrel slimmed**: `src/index.ts` no longer re-exports bridges, CMS adapters, admin components, analytics, schema validation, or database adapters. Import these from their subpaths instead:
+  - `featuredrop/bridges` — SlackBridge, DiscordBridge, etc.
+  - `featuredrop/admin` — ManifestEditor, AudienceBuilder, etc.
+  - `featuredrop/schema` — validateManifest, featureEntrySchema, etc.
+  - `featuredrop/ci` — diffManifest, validateManifestForCI, etc.
+  - `featuredrop/flags` — createFlagBridge, LaunchDarklyBridge, etc.
+  - `featuredrop/analytics` — AnalyticsCollector, PostHogAdapter, etc.
+- **Zod moved to optional peer dependency**: Only needed if you use `featuredrop/schema`. Core no longer requires it.
+
+### Performance
+
+- Core bundle reduced from 34.31 kB to 3.01 kB gzip (91% reduction)
+- Strict bundle budgets enforced: core < 5 kB, react < 55 kB, vue < 10 kB, svelte < 5 kB
+- Tree-shaking now works correctly — importing `isNew` from `featuredrop` pulls < 3 kB
+
+### Documentation
+
+- Added 6 framework adapter docs: Vue, Svelte, Solid, Preact, Angular, Web Components
+- Redesigned landing page with 13 sections, live interactive demos, comparison table, animated stats
+- Expanded release lifecycle, launch flow, admin components, and migration guide
+- Component gallery upgraded with live demos, props tables, and install snippets

+- Total docs pages: 57 (up from 48)
