Amazon Kindle Publishing Guidelines version 2017.3 is now available. (Refresh the page if you see the old guidelines.)

Not much changed, mostly clarifications. No new features.

They did add some information on SVG: "SVGs are not supported in iOS. Enhanced Typesetting does not support SVG images."

It does seem to be true that it's a lossy format.

I came across an interesting error message string in Kindle Previewer 3.17:

Quote:
Use an EPUB validator to ensure that the EPUB file is valid and well-formed. Refer to the Formatting Guide for Enhanced Typesetting to see the list of potential epub issues that could cause this failure.
I have never heard of the "Formatting Guide for Enhanced Typesetting" before. Has anyone else? (A Google search didn't turn up anything.)

Perhaps this is an upcoming supplement to the "Amazon Kindle Publishing Guidelines".

There is a mistake in section 9.3.8. It says...

Quote:
Do not embed the following fonts, which are currently available on Kindle devices and applications:
For example, it lists Bookerly as not allowed to be embedded. But, Amazon is wrong when it says it's available on Kindle devices. Some yes, some no. The Kindle Touch (for example) does not have Bookerly.

One font not mentioned is Charis SIL. So obviously, it's OK to embed.
