MobiVerse 2.3.0 — Browse, Smart Import & Paginated Reader

MobiVerse 2.3.0 (11) — macOS

MobiVerse 2.3.0 turns the macOS app into a complete local reading workspace: browse legal ebook sources, validate downloads, review locally detected book types, convert through the correct text or comic pipeline, and read in a refined paginated preview. No ebook website is bundled, promoted, or endorsed.

Browse and downloads

• New Shelf / Browse workspace with an isolated persistent WKWebView, tabs, back/forward/reload/home controls, address/search input, and persistent website sessions.
• Chrome-style bookmark star: click to add the current site and show its chip below the address bar; click again to remove both. Bookmarks are user-managed and the start page contains no fixed ebook sites.
• Download tray with progress, pause, cancel, retry, source domain, duplicate-name handling, configurable download location, and Finder reveal.
• Downloads are staged and validated using file signatures, MIME type, extension, and real content. HTML error pages, executables, and disguised or unsupported files are rejected before import.
• Redesigned browser settings in MobiVerse's warm editorial palette, including download location, bookmark management, and one-click clearing of cookies, cache, and browser history. Books, bookmarks, and conversion history are not deleted.
• The online browser and offline EPUB preview use separate WebView configurations. Preview remains non-persistent, blocks scripts and remote resources, confines local paths, and cannot share browser cookies.

Intelligent local import

• Browser downloads, file selection, and drag-and-drop now share one analyze → review → convert flow.
• Local-only classification identifies text books, comics/image books, or uncertain files and shows confidence plus concise evidence. Nothing is uploaded to an AI or remote classification service.
• Batch review supports user overrides and left-to-right or right-to-left comic direction. Low-confidence items require a choice.
• EPUB files are safely parsed, classified, given a cover, and added directly to the shelf without unnecessary repackaging.
• Downloaded but unconfirmed items are persisted for later review; older conversion history remains backward-compatible without reprocessing.

Conversion and Japanese EPUB 3 repair

• Explicit text-reflow and comic-fixed-layout conversion profiles now route each book correctly.
• Text books avoid comic CSS, fixed-layout metadata, RTL metadata, and comic post-processing. Text PDFs use Calibre reflow.
• Comics retain image normalization, fixed-layout EPUB metadata, reading direction, Apple Books compatibility behavior, and the native PDFKit fixed-layout path.
• AZW/MOBI text conversions now target EPUB 3.
• Japanese ruby annotations (ruby / rt) are preserved. Before EPUBCheck, MobiVerse automatically repairs invalid XML IDs, broken stylesheet/resource references, and NCX play order instead of deleting annotations.
• EPUBCheck zero-warning summaries are recognized correctly.

Reader and appearance

• Reflowable EPUB preview is now a viewport-fitted paginated reader with horizontal page turns, refined typography, reading themes, and reader controls instead of vertical chapter scrolling.
• Comic/image EPUB pages fit the reader and turn horizontally.
• Reopening a preview restores the exact section and page for text books and the exact page for comics, with legacy position data supported.
• Shelf, Browse, settings, import review, and preview chrome now adapt consistently to macOS light and dark appearances.
• New persistent appearance control: Follow System, Light, or Dark.
• Dark-mode still-life artwork now uses a high-resolution antialiased asset and matches the light illustration's visual size.

Packaging and compatibility

• The macOS DMG always includes Calibre, EPUBCheck, and the Java runtime required by EPUBCheck. No separate conversion or validation install is needed.
• Existing output collision protection, conversion progress, retry, cover cache, reports, Finder reveal, deletion, and history behavior are preserved.
• macOS only in this release; the Windows release remains 2.2.0.
• Apple Silicon (arm64), macOS 14 or later.

Verification

• 43 automated tests across 13 suites passed.
• DMG mounted and verified successfully; embedded app signature and bundled Calibre, EPUBCheck, and Java were checked.
• SHA-256: 3ac2d07a52749cabcda3f2c69848d2f726662abe5e021a1207c4b0a308c2c34f

Installation note

This build is ad-hoc signed and is not Apple-notarized. macOS may show an “Apple could not verify MobiVerse” warning for an internet download. A Developer ID-signed and notarized release requires the project owner's Apple Developer signing credentials.
