Kovid Goyal has released Calibre 9.10, the latest version of the beloved open-source e-book management suite. This release focuses on a major upgrade to the built-in Content Server, expanded CSS support in the e-book editor, and a handful of quality-of-life improvements across the board.
What's New
Content Server gets a modern UI The Content Server, Calibre's built-in web interface for accessing your library from a browser, has received a brand-new "modern" design featuring a sidebar for easier navigation. It also now supports installation as a Progressive Web App (PWA) when accessed over HTTPS, meaning you can pin your Calibre library as an app on your desktop or device.
CSS Level 4 selector support The CSS parser in Calibre's e-book editor now supports CSS Level 4 selectors, which gives authors and editors much more precise control when styling e-book content.
PNG to JPEG/WEBP conversion in Edit Book The Edit Book tool gains a new option to convert PNG images inside an e-book to JPEG or WEBP format, handy for reducing file size without re-exporting the whole book.
Annotations browser improvements You can now filter displayed annotations by custom annotation styles, making it easier to navigate books with multiple highlighting colours or note types.
Cover grid scaling The library cover grid now scales images larger to better fill the available viewport, giving the library view a more polished, photo-gallery feel.

- Fixed CSV export of the Comments field.
