The Markua 0.30 Specification is being implemented on Leanpub. We just launched the first beta version of it!
See this post in the Leanpub Author Forum for more information.
Our Markua 0.30 support is not just an upgrade; it is a huge overhaul of our book generation code. So, some things which have worked for the better part of the past decade may not work in Markua 0.30 books yet!
Please note that we are leaving Leanpub Flavoured Markdown and Markua 0.10 books unchanged. The Markua 0.30 work is being done totally separate from the Leanpub Flavoured Markdown and Markua 0.10 support. Any bugs with our Markua 0.30 support will only affect Markua 0.30 books.
If you did not set your book to use Markua 0.30, this has no effect on you!
Below is a list of features that have been tested to at least partially work:
Note that the tests done were not entirely thorough, but rather just tested basic functionality...
Basic PDF, EPUB, and MOBI generation
Image, code, math, table, resources for PDF and EPUB in Monaco, Github, and Dropbox
Verso page content
Title page images
Document settings, attributes, and directives (at a parsing level)
Frontmatter, mainmatter, and backmatter
Headings (setext, ATX, and part headings)
Raw HTML is removed
Link reference definitions
Blockquotes, asides, and blurbs
Bulleted and numbered lists
Footnotes and endnotes (But both act the exact same in EPUB currently)
Crosslinks and ids
Soft and hard line breaks
Configurable soft line breaks
Span attribute lists
Concatenating files and blank lines
Index entries for PDF
If you want to enable the configurable soft line break support, what you currently do is you choose a Custom theme and use the setting about how to interpret single newlines. This is actually a bug: we should have had it as a generation setting. So, at some point that setting will move to the Settings > Generation Settings page.
Not Implemented Yet
Below is a list of features that have been found to not work:
Insertion directives in EPUB and MOBI
Most attributes for resources
GIF resources break generation
Paragraph continuations (paragraph attribute)
