Hi everyone,

We have just released an update for KinBo Comic Converter focusing on fixing a major cover page display issue on Kindle devices.

What's Fixed:
* Kindle Cover Display: Fixed an issue where custom cover images or the first page did not show up as book covers in the Kindle library view.
* EPUB 3 / Legacy Metadata Alignment: The output generator now writes all necessary descriptors required by Amazon's ingestion system (Send-to-Kindle) and local Kindle parsers:
- Added the mandatory properties="cover-image" to the manifest image item.
- Included retro-compatible <meta name="cover" content="..." /> tags in the metadata block.
- Added an epub:type="landmarks" navigation map in nav.xhtml for EPUB 3 compliance.
- Added a <guide> section to the OPF package document to support older Kindle models.

This ensures that whether you upload via Send-to-Kindle (which uses standard EPUB 3 processing) or sideload via USB, Kindle devices will correctly generate, cache, and display your comic book covers!

Let us know if you run into any issues or have feedback!

Happy reading!
