[0.29]

• Clarify that entities can't be used to indicate structure (#474). For example, you can't use * instead of * for a bullet list, or 
 to create a new paragraph.

• Limit numerical entities to 6 hex or 7 decimal digits (#487). This is all that is needed given the upper bound on unicode code points.

• Specify dropping of initial/final whitespace in setext heading content (#461).

• Add example with a reference link definition where the reference is never used (#454).

• Add example with setext header after reference link defs (#395).

• Clarify that script, pre, style close tags can begin an HTML block (#517).

• Remove meta from list of block tags in start condition #6 of HTML blocks (#527). meta tags are used in some inline contexts (though this isn't valid HTML5), e.g. in schema.org.

• Disallow newlines inside of unquoted attributes (#507, Shyouhei Urabe) as per HTML spec: https://html.spec.whatwg.org/multipage/syntax.html#unquoted.

• Remove vestigial restriction in list item spec (#543). The "not separated by more than one blank line" was a left-over from an earlier version of the spec in which two blank lines ended a list.

• Fix tests where list items are indented 4+ spaces (#497). The tests did not accord with the spec here; these lines should be continuation lines (if no blank space) or indented code blocks (if blank space).

• Clarify tildes and backticks in info strings (#119). We disallow backticks in info strings after backtick fences only. Both backticks and tildes are allowed in info strings after tilde fences. Add example.

• Indicate that info string is trimmed of all whitespace (#505, Ashe Connor). As noted in github/cmark-gfm#60, the info string is not only trimmed of "spaces" (U+0020) but also of tabs.

• Don't strip spaces in code span containing only spaces (#569). This allows one to include a code span with just spaces, using the most obvious syntax.

• Add example w/ reference link w/ empty destination in <> (#172).

• Disallow link destination beginning with < unless it is inside <..> (#538). This brings the description in line with the spec example:
  [foo]: (baz)

   [foo]
   .
   <p>[foo]: <bar>(baz)</p>
   <p>[foo]</p>
  

• Allow spaces inside link destinations in pointy brackets (#503). This reverts a change in 0.24 and should make things easier for people working with image paths containing spaces.

• Remove redundant condition. We don't need to specify that the absolute URI in an autolink doesn't contain <, since this is specified in the description of an absolute URI.

• Add additional spec examples involving link destinations in <> (#473).

• Add test for [test](<url\>) (#562).

• Disallow unescaped ( in parenthesized link titles (#526).

• Add example showing need for space before title in reference link (#469).

• Add codepoints for punctuation characters (#564, Christoph Päper).

• Clarify the left- and right-flanking definitions (#534, Jay Martin).

• Match interior delimiter runs if lengths of both are multiples of 3 (#528). This gives better results on a***b***c without giving bad results on the cases that motivated the original multiple of 3 rule.

• Add another test case for emphasis (#509, Michael Howell).

• Code spans: don't collapse interior space (#532).

• Simplify revisions to code span normalization rules. Remove the complex rule about ignoring newlines adjacent to spaces. Now newlines are simply converted to spaces.

• Replace image 'url' with 'destination' (#512, Phill).

• Add some links for occurrences of "above" (#480).

• Various typo fixes (#514, Kenta Sato; #533, nikolas; tnaia, #556; #551, Grahame Grieve).

• Create .gitattributes so that changelog.txt is highlighted as markdown (#499, Christoph Päper).

• Update GitHub links (Morten Piibeleht).

• Update references to container and leaf block headers to use the correct pluralization (#531, Elijah Hamovitz).

• Rephrase example #111 to indicate that the rendering is not mandated (#568).

• Improve documentation of parsing strategy (#563). Note that openers_bottom needs to be indexed to delimiter run lengths as well as types.

• make_spec.lua: Fix migration of children nodes in create_anchors (#536, Zhiming Wang). This resulted in some bugs in the rendered spec (where words would be dropped from links).

• Fix dingus link when double clicking Markdown code (#535, Zhiming Wang). Prior to this commit, the link opened is always /dingus/?text= (no text).

• Add spec.json generator to Makefile (M Pacer).
