hMailServer 6.1.0 - a complete UI/UX modernization across the desktop Administrator, a brand-new web interface, and the installer.
Web Control Deck (new)

A sleek, futuristic web admin UI served directly by the built-in REST API listener - no extra components. Enable \RestApiPort\ in hMailServer.INI and browse to the server: live dashboard with animated counters and session stats, domain & account management, delivery-queue retry/delete, and publish-ready DANE TLSA records. Light/dark themes with toggle; sign-in uses the administrator credential.
Administrator (desktop)

    Full light/dark theme engine: deep-space dark and clean light palettes applied across every pane and dialog, dark window title bars, native dark scrollbars, themed menus
    Theme toggle in the View menu - follows the Windows app-mode preference by default, choice persisted
    Ctrl+K command palette: fuzzy-search every settings page and jump straight to it
    Modernized dashboard: glow accents, eased value animations, hover-highlight stat cards

Installer

    Modern wizard branding
    Ships the WebAdmin payload

Server core is unchanged from 6.0.0 build 4 apart from the new web-page endpoint. Validated by the full regression suite: 898/898 tests passing, zero failures (MariaDB backend, live SpamAssassin + ClamAV, TLS 1.2/1.3 end to end).
