0.12.30 March 8, 2013 Note about side-loading files on Kobo devices. An issue with side-loading files onto Kobo devices causes the wrong rendering engine to be used for our EPUB3 files, resulting in (among other things), the absence of a TOC for the book. This version of ebookmaker adds an EPUB2-style table of contents in the EPUB3 files to mitigate this issue, as well as to improve compatibility of our EPUB3 files on older devices, such as Nook. This is common practice in the ebook industry. We will continue to produce EPUB2 files, which often render better on older devices, as well as on the older Kobo rendering engine currently invoked for side-loaded books. Kobo is aware of the issue with side-loaded EPUB3, and we expect that the issue will eventually be fixed. In the meantime, Kobo rendering of EPUB3 should NOT be considered when authoring new HTML5 books.
