 ### New Features
 
 - **DOMPurify for NomadNet**: Added `dompurify` dependency and global `DOMPurify` in frontend entry so MicronParser sanitizes content when browsing Nomad Network nodes; removes "DOMPurify is not installed" warning in AppImage and packaged builds.
+- **Identities page**: Import and Export all identities in header (next to New Identity). Per-identity key actions: export key file and copy Base32 shown on hover for the current identity card only. Import modal with upload key file and paste Base32. Backend `GET /api/v1/identities/export-all` returns a ZIP of all identity key files.
+- **Contacts page**: Contacts management UI with routing, localization (en, de, it, ru), and LXMA contact handling. Public key retrieval and tests for LXMA URI handling.
 
 ### Improvements
 
 - **Micron editor**: Button label changed from "Download" to "Save" on the micron editor page (en: Save; de: Speichern; it: Salva; ru: Сохранить).
 - **Release workflow**: Include `meshchatx-frontend.zip` in release assets (was generated and checksummed but not uploaded). Add Linux arm64 build step (AppImage + deb) via `dist:linux-arm64`. Release `files` list now includes `*.zip`.
 - **Community interfaces**: Replaced RNS Testnet Amsterdam and BetweenTheBorders with Quad4 hub (62.151.179.77:45657 TCP). Removed outbound health checks: suggested community interfaces are now a static list with no TCP probes to the internet.
+- **Identities**: Removed top key-control card; key actions moved to per-card hover. Message count and LXMF/LXST addresses on identity list; backend message_count for current identity.
+- **About page**: Security & Integrity section: signed (shield-check) icon and "No integrity violations" badge use green styling in dark mode; status pill has dark-mode emerald variants.
+- **Version management**: Single source of truth is `package.json`; run `pnpm run version:sync` to update `meshchatx/src/version.py`. Build runs sync automatically.
