Is there a way to download the latest commit as a compiled binary for macOS? I couldn't find one, so I cloned the repo using git and ran "calibre-debug -g", which showed the version as "8.1.1*", which I'm pretty sure tells me I'm running the latest commit.

I sent a KEPUB to my Kobo, checked how it looks, and what do I see? Hyphens at the end of lines!!

I opened a chapter to view the code, and here's what I now see:

    <style type="text/css" id="kobostylehacks">div#book-inner { margin-top: 0; margin-bottom: 0; }</style>
    <style type="text/css" id="kepubify-extra-css">
* {
    /* Vendor-prefixed CSS properties for hyphenation. Keep -webkit first since
     * some user agents also recognize -webkit properties and will apply them.
     */
    -webkit-hyphens: auto;
    -webkit-hyphenate-limit-after: 5;
    -webkit-hyphenate-limit-before: 3;
    -webkit-hyphenate-limit-chars: 8 3 5;
    -webkit-hyphenate-limit-lines: 2;

    /* CSS4 standard properties for hyphenation. If a property isn't represented
     * in the standard, don't put a vendor-prefixed property for it above.
     */
    hyphens: auto;
    hyphenate-limit-chars: 8 3 5;
    hyphenate-limit-lines: 2;
    hyphenate-limit-last: page;
}

h1, h2, h3, h4, h5, h6, td {
    -webkit-hyphens: none !important;
    hyphens: none !important;
}
</style>

So I think you fixed it!! It looks like adding the hyphenation under 'kepubify-extra-css' was the trick.

Thank you so much, Kovid!! Sorry to be such a bother, now I shall return to reading Dan Moren's The Nova Incident...
