Vellum 2.6.4 is a minor update with the following improvements:

• Athelas and Iowan print edition fonts are again available on macOS Catalina
• Fixed centering of a Trace chapter heading in Apple Books
• Corrected inset of a Verse style on Kindle
• Fixed importing manuscripts with a capitalized DOCX extension
• Hyphenation is now disabled within a Dedication
• Added translations for the Endnotes (“Notes”) element

This release is a free update, available now.

Apple has just released Catalina, the newest version of macOS.

If you choose to upgrade to Catalina, you’ll need the latest version of Vellum. You can update Vellum using Check for Updates.

Vellum has been tested on Catalina and includes fixes for potential issues with this new version of macOS. If you experience any problems with Vellum, please let us know.

With Vellum 2.6.2, you can (once again!) generate mobi files for Kindle. Vellum uses a new generation method that is compatible with coming updates to macOS.

To generate a mobi file with Vellum, you will need Kindle Previewer on your Mac. If you don’t already have it installed, Vellum will provide instructions the first time you generate.

Vellum will generate mobi files by default. If you prefer the new Kindle.epub format, though, that option is still available in Preferences.

This is a free update, available now.

After receiving feedback from our users, we’re announcing that in our next update, Vellum will return to generating mobi files for the Kindle platform.

Vellum recently moved away from creating files in the mobi format, as the KindleGen utility that Vellum used to convert these files is not compatible with the forthcoming version of macOS. To generate mobi files in a manner that works with macOS Catalina, Vellum will switch to use conversion tools bundled with Amazon’s Kindle Previewer utility.

Because we have also received some positive feedback about the new Kindle.epub files, generating Kindle-specific EPUB will remain as an option. This option will also serve as a fallback in case the conversion tools in Kindle Previewer fail in the future.

This update is currently planned for October 2. In the meantime, if you need to convert Kindle.epub files to the mobi format, you can do so by opening your file in Kindle Previewer and using the Export option. If you have any questions, please contact us.

With Vellum 2.6, you’ll find generation for Kindle to be more secure, more reliable, and much faster. That’s because Vellum no longer relies on Amazon’s KindleGen utility to convert files to the mobi format.

Instead, Vellum will now generate a Kindle-specific EPUB file.

Ready for Catalina

If you’ve been using macOS Mojave, you’ve likely seen warnings that KindleGen is not optimized for your Mac, and won’t work with the next version of macOS. That version is Catalina, and it’s coming next month.

With Vellum 2.6, you won’t see any of these warnings, and you’ll be ready for Catalina.

Questions & Answers

Here are some answers to questions you might have about this change:

How do I publish my Kindle ebook?

You can upload the Kindle.epub file straight to KDP. No additional conversion is necessary. Your readers won’t see any difference in the books they receive from Amazon.

How can I check my ebook beforehand?

The best way to proof your Kindle ebook is with Amazon’s Kindle Previewer, and it’s the only way to view your book with Enhanced Typesetting before you publish. You can open a Kindle.epub file directly in Kindle Previewer.

How do I send an advanced copy to readers?

To manage your ARCs, we recommend using BookFunnel. BookFunnel can accept the Kindle.epub file generated by Vellum and will automatically convert it if necessary.

If you don’t use BookFunnel, you can export a mobi file from Kindle Previewer and send this file to your readers.

Also in Vellum 2.6:

• You can now add an affiliate code for links to Google Play

• Fixed a rare problem with incorrect page numbers
• Improved editing margin values in regions that use a comma

Update 10/02/19: Mobi output is again available in Vellum 2.6.2.

If you’ve installed Mojave, you’ve likely seen warnings about Amazon’s KindleGen utility, which has not been optimized for current versions of macOS. As those warnings inform, older 32-bit programs like KindleGen won’t run in Catalina, the forthcoming version of macOS.

We’ve received many questions about whether Amazon will publish an updated 64-bit version of KindleGen in time for the release of Catalina, due this fall. We don’t know the answer to that. What we do know is that KindleGen hasn’t received an update since 2013, and shows many signs of being abandoned by Amazon.

Given this, Vellum will soon move away from using KindleGen entirely. Instead, Vellum will produce a Kindle-specific EPUB file.

You should find this makes little difference to your workflow. When you’re ready to publish, you’ll be able to upload this file to KDP without any extra conversion; your readers won’t see any difference. To proof your book beforehand, you can open this file directly in Kindle Previewer. And in situations where you do need a mobi file (to send an ARC, for example), you can make use of the Export command in Kindle Previewer.

By avoiding KindleGen, you’ll find generation to be much faster, more reliable, and free of any warnings about 64-bit compatibility.

This change will be released in the next update to Vellum, due in early September, and well before the release of Catalina. We’ll have more details at that time.

Staying up for late-night publishing? Turn down the lights with Dark Mode!

Introducing an all-new, darker color scheme for Vellum. With low-brightness backgrounds and a light-on-dark editor, it’s designed to be used in dim environments.

Dark Mode can be just the thing for working at 2 AM, but we won’t blame you if you want to use it all the time!

Dark Mode requires macOS Mojave. You can activate it in the System Preferences for your Mac.

Also in this Update

• Large Print editions are now generated into a separate folder, and won’t overwrite a standard print edition.
• You can now use the Numbered toggle to disable numbering for Parts.

You’ll find these additions in Vellum 2.5.2, a free update. This version requires macOS Sierra or newer.

If you attempt to proof your generated books using the Kindle program for Mac, you may encounter a few problems, especially with ornamental images:

We’ve received reports of several issues with this recent update to Kindle for Mac:

• Ornamental break images can appear oversized and may overlap text
• Heading ornaments can disappear entirely
• The cover image may show through to other pages
• The Find command can show incorrect text
• The application can freeze when turning pages
• Links within the book can be difficult to click

As far as we know, these issues only occur when you sideload a book for testing. Books purchased by readers and delivered by Amazon should not exhibit these issues.

We’ve reported these issues to Amazon, but we have no way of knowing when they will address these problems with the Kindle for Mac program.

To proof your book, we recommend using Kindle Previewer. Kindle Previewer is the most accurate way to view your book, and will not exhibit problems like the above.
