Now on [http://spec.commonmark.org](http://spec.commonmark.org). Changes from 0.13:

- Clarified indented code blocks. Previously the spec said, wrongly,  
that a blank line was needed between a paragraph and a following  
code block. It is only needed between a code block and a following  
paragraph (due to lazy continuations). (Thanks to textnut.)

- Added definitions of whitespace, unicode whitespace, punctuation,  
ASCII punctuation (#108).

- Improved rules for emphasis and strong emphasis. This improves  
parsing of emphasis around punctuation. For background see  
[http://talk.commonmark.org/t/903/6](http://talk.commonmark.org/t/903/6). The basic idea of the change  
is that if the delimiter is part of a delimiter clump that has  
punctuation to the left and a normal character (non-space,  
non-punctuation) to the right, it can only be an opener. If it has  
punctuation to the right and a normal character (non-space,  
non-punctuation) to the left, it can only be a closer. This better handles  
cases like

- Added test case for link-in-link-in-image (#252).

- Fixed broken internal references.

- Added another example of an unclarity in the canonical Markdown  
syntax description.

- Reworded the principle of uniformity to be more general; it applies  
to all container blocks, not just list items.

- Added a rule for empty list items (#242).

- Clarified precedence of empty list items over setext header lines  
(#95).

- Added an example with two blank lines in fenced code in a sublist (#180).

- Added an explicit CC-BY-SA license to the spec (#55).

I just pushed another release, 0.15, that fixes some seriously misleading typos in 0.14.
