Zin Flow v2.7: Customize Your eBooks with Cover & Metadata Editing

Introduction

We are excited to announce Zin Flow v2.7, a release focused on giving you more creative control over your eBooks. From customizing covers and metadata to a smoother export experience, this update empowers you to create truly personalized EPUB files.

Custom EPUB Cover & Metadata Editing

The headline feature of version v2.7 is the ability to personalize your eBooks before export.

  • Custom Cover Images: You can now replace the default EPUB cover with your own image, making each eBook uniquely yours.
  • Full Metadata Control: Edit the title, author, language, publication date, and publisher. Your generated eBooks now carry the exact information you want.
  • TOC Display Options: A new option lets you keep the EPUB table of contents as a reader navigation resource, instead of displaying it as a TOC page within the reading flow.

EPUB Export Compatibility Fixes

We’ve made significant under-the-hood improvements to ensure your EPUB files pass strict validation and work flawlessly across devices.

  • XML Entity Handling: Fixed “undeclared nbsp entity” errors reported by EPUBCheck, ensuring your exports are spec-compliant.
  • Cross-Device Stability: HTML-specific entities are now converted to universal numeric character references ( ), guaranteeing consistent rendering on any e-reader brand or model.

macOS: Tag Management in Sidebar

Mac users can now delete tags directly from the sidebar via a right-click context menu — a small but powerful workflow improvement for keeping your library organized.

Vietnamese Localization

Zin Flow now speaks Vietnamese. The interface has been fully localized across all major screens and prompts, providing a more welcoming experience for Vietnamese-speaking users.

Smarter Export Flow

We’ve refined the export process to handle edge cases more gracefully and give you greater control.

  • Refresh on Demand: When export detects articles that aren’t ready, instead of a simple prompt, Zin Flow now asks if you’d like to refresh immediately — and notifies you via toast when done.
  • Skip Empty Articles: Articles with no content can now be skipped during export. Choose from “Refresh”, “Skip & Export”, or “Cancel” to keep your workflow moving.

Conclusion

Zin Flow v2.7 is all about personalization and polish. Whether you’re adding a custom cover, exporting for a specific e-reader, or managing your library on Mac, these updates make the entire experience smoother and more flexible.
