Vellum 1.4.2 includes changes to work around problems with Amazon’s Enhanced Typesetting feature.
In eBooks with Enhanced Typesetting enabled, some chapter headings were improperly centered, and drop caps beginning with a quote could display blank pages. This update adjusts Vellum’s Kindle-specific output to avoid both of these issues.
Vellum 1.4.2 is a free update, available now.
