[0.18.0]

• Added nextNonspace, blank, indent properties to Parser.
• Factored out advance-to-nonspace code into findNextNonspace.
• Put block starts into blockStarts property of Parser. Now almost all block-specific material has been moved out of incorporateLine.
• Removed parameter from addLine.
• Simplified code, removed matchAt.
• Small optimization in entityToChar
• Use charCodeAt in a few places where charAt was used.
• Added peek() function in blocks. This ensures we check bounds before calling charCodeAt.
• Use peek instead of raw charCodeAt in inlines.js.
• Dingus improvements:
  • Use ACE editor in dingus. Implemented L->R sync scroll. Also, the block containing the cursor is highlighted on the right.
  • Split code from dingus.html into separate file dingus.js.
  • Split CSS into separate file, dingus.css.
  • Added debounce.
  • Moved dingus code to dingus/ directory. dingus/Makefile builds commonmark.js in the dingus directory. So to deploy, you just need to copy the dingus directory.
  • Use local copies of js dependencies. Instead of including these in the repository, though, we have the Makefile install them with bower.
  • Fixed one-off error in line number calculation.
  • XML and HTML are now same font size.
  • Allow line wrapping in editor.
  • AST window now scrolls like HTML window.
• Updated reNonSpace for new whitespace definition in spec.
• Added smart punctuation parsing option.
  • Added options param to InlineParser. options.smart triggers smart punctuation parsing.
  • Added --smart option to bin/commonmark.
  • Implemented "smart" parsing of dashes, ellipses, quotes. The algorithm is the same as in cmark.
  • Renamed handleEmphasis -> handleDelims.
  • Added benchmark with smart.
  • Added checkbox for smart to dingus.
• Fixed code example for walk.
• Made isContainer a getter to conform to README (#7).
• Allow list start number of 0 in HTML writer (#10).
• Fixed use of isContainer in XML writer. isContainer is now a getter, not a function.

[0.17.1]

• Reorganized block parsing in a more modular way. There is now a blocks property of the parser that contains information about each type of block, which is used in parsing. Ultimately this will make it easier to extend the library, but the project is still only partially completed.
• Code cleanup and simplification, with some performance optimizations.
• Removed version from bower.json. Bower takes version from tags.
• Initialize some properties at beginning of 'parse'. This fixes some mistakes in source position when the same Parser object was used to parse multiple times (#3).
• Made parsing of backslash escapes a bit more efficient.
• Removed refmap parameter of InlineParser.parse(). Instead, set the refmap property before running the parser.
• Set _string_content to null after using, allowing it to be GCd.
• Removed _strings; just append to _string_content. This gives better performance with v8.
• Format benchmarks so that samples are linked.
• Added in-browser benchmark.
• Added API documentation to README.
• xml renderer: use sourcepos attribute, not data-sourcepos.
• Changed license to 2-clause BSD. Added clause for spec.

[0.17.0]

• Renamed DocParser -> Parser. Note: library users should update their code or it will break.
• Added normalize-reference.js. This does a proper unicode case fold instead of just using toUpperCase. It is also faster, partly because we can do one pass for space and case normalization.
• Removed artificial distinction btw FencedCode, IndentedCode in blocks.js.
• Removed vestigial ReferenceDef node type.
• Added getters and (in some cases) setters for "public" properties of Nodes. Renamed non-public properties to start with underscore. This will allow us to keep the API stable while changing the underlying data structure. And it will avoid exposing properties that have only an instrumental value in parsing.
• Removed Node.toObject().
• Rename bullet_char -> bulletChar.
• Check for blank line before checking indent in Item.
• Removed unnecessary setting of default tight=true in finalize. We do that when the listData object is initialized.
• Performance optimization - avoid repeating scan for nonspace.
• Moved check for closing fence to close-block-check section. This is a more logical arrangement and addresses jgm/CommonMark#285.
• Added offset property to DocParser. Use this in addLine, instead of offset parameter, which has been removed.
• Implemented new spec for emphasis and strong emphasis with _.
• html.js - explicitly specify second parameter of escapeXml.
• Fixed escaping error in CDATA regex.
• Removed some dead code and fixed incorrect call to addChild with three arguments (Robin Stocker).
• Adjust lastLineLength before returning after close fence.
• Propagate lastLineBlank up through parents. Previously we just kept it set on the bottom child. But this will give a quicker determination of lastLineBlank.
• Moved continuation checks & finalizers into blocks property of Parser. This is a first step towards keeping the code for each kind of block in a central place, rather than spread all over the code base. This is preparatory for a more modular structure, where each type of block has a record describing how it is parsed and finalized. Eventually this will also contain functions for checking for a block start, and metadata that determines how line data should be handled.
• Added currentLine property to Parser.
• Renamed first_nonspace -> next_nonspace.
• Put generated commonmark.js in dist/ rather than js/.
• Miscellaneous code cleanup.
• Split JS code into (this) independent repository.
• Added detailed benchmark with samples (make bench-detailed).
• Added dist/commonmark.js to repo (for bower).
• Added bower.json (jgm/CommonMark#288).
• Updated test suite. Now shows how performance depends on length in pathological cases.
• Don't use -1 as second param for .slice. This seems to cause a deoptimization, as reported by node --trace-deopt.
• Added CONTRIBUTING.md.
• Added .travis.yml to test against various node versions.
• Renamed changelog.js.txt -> changelog.txt.

[0.16]

• Improved regex for HTML comments (#263).
• Fixed CDATA regex (#267).
• Use linked list instead of arrays in AST: the same doubly linked node structure as cmark uses. This simplifies some code and eliminates the need for recursive algorithms, so we can render deeply-nested structures without stack overflows.
• Use children instead of label (in Image and Link), inline_content (in Paragraph), and c (in Emph and Strong).
• Renamed the c property to literal to match libcmark.
• Use literal rather than string_content property for code blocks, HTML. string_content is reserved for raw string content that has yet to be parsed as inlines.
• Improved end lines (#276).
• Added a node walker, for easy AST traversal (see node.js).
• Regularized position information into a sourcepos property. Added end column information.
• Renamed html-renderer.js to html.js.
• Replace NUL characters with U+FFFD, as per spec.
• Optimized code, resulting in significant performance gains. (We've gone from being twice as fast as showdown.js to being three times as fast, on par with marked.)
• Made tight a property of list_data rather than Node.
• Added options to renderer, parser objections.
• Added a --sourcepos command line option to js/bin/commonmark.
• HTML renderer now throws an error on unknown tag type (which indicates a programming error).
• Removed ansi.js code from the source tree. The test suite now uses its own mini ansi colors implementation.
• Added --time option to js/bin/commonmark.
• Added an XML renderer (XML representation of the AST, matching Commonmark.dtd).
• Changed url property to destination to match cmark and spec.
• Added js/common.js to hold some common code, like string unescaping and URI normalization.
• Use decodeURI instead of unescape.
• Added some "pathological" test cases to test suite.
