I made a DP forum posting for this topic: https://www.pgdp.net/phpBB3/viewtopic.php?f=27&t=68280 Here is what I submitted: For those who test DP productions prior to final upload at https://upload.pglaf.org : With thanks to Eric Hellman, one of our programmers, there is now a new updated version of ebookmaker (previously known as epubmaker). If you notice any problems, please email me: gbnewby@pglaf.org or, if it is more of a feature request, submit an issue to the tracker here: https://github.com/gutenbergtools/ebookmaker The new version is here: https://ebookmaker2.pglaf.org After some testing, we will do two things: 1. Update https://ebookmaker.pglaf.org (and variations) to point to the new version. 2. Replace the production version on www.gutenberg.org to use the new version for all new uploads. Depending on whether problems are encountered, this change might occur in a week or so. Or, we might need a longer testing period. We will then gradually run the new version on the previous eBooks (i.e., #1-#60000something). For the most part, this new version of ebookmaker is indistinguishable from the old. There are a number of under-the-covers improvements, including getting it into a source code repository with better documentation for installation and dependencies. It also includes capability to make a simple book cover, when cover images are not already part of the eBook. It also handles some error conditions or input variations more effectively than the old version. - Greg
