+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [10.0.0] - 2019-09-11
+### Security
+- Fix quadratic parse time for some combinations of pairs, #583. Algorithm is
+  now similar to one in reference implementation.
+
+### Changed
+- Minor internal structs change, to make pairs parse more effective (cost is
+  linear now). If you use external "pairs" extensions, you need sync those with
+  "official ones". Without update, old code will work, but can cause invalid
+  result in rare case. This is the only reason of major version bump. With high probability you don't need to change your code, only update version dependency.
+- Updated changelog format.
+- Deps bump.
+
+
+## [9.1.0] - 2019-08-11

+
+
+## [8.2.0] - 2016-12-01
+### Changed

+
+
+## [8.0.0] - 2016-09-16
+### Changed

+  autodetected links by default. `md.linkifier.set('---', true)` will return old
+  behaviour.
+- Major version bumped, because internals or `linkify-it` was changed.
+  You will not be affected anyhow, if not used direct access to
+  `require('linkify-it/re')` for customizations.
+

+  immutable after renderer call.
+
+

+### Fixed
+- Process `\r` the same way as `\n` and `\r\n\`, #252.
+
+
+## [6.0.4] - 2016-05-30
+### Added
+- Added `Token.attrGet()` method for convenience, #251.
+
+
+## [6.0.3] - 2016-05-30
+### Security
+- Security fix: possible ReDOS in `linkify-it` (forced bump of `linkify-it` &
+  `uc-micro` dependencies). New installs will use fixed packages automatically,
+  but we bumped `markdown-it` version for sure & for web builds.
+
+
+## [6.0.2] - 2016-05-16
+### Fixed

+### Fixed
+- Improve support of missing values in tables, #224.
+
+
+## [6.0.0] - 2016-02-11
+### Changed

+  (multiline setext headers, no spaces inside links, ...). API was not changed.
+- Fit CM 0.24 spec requirements.
+
+### Fixed

+- Allow single column and mismatched columns count in tables.
+- Smartquotes: take into account adjacent tokens.
+- Fill `content` property in image token with `alt` source.
+
+
+## [5.0.2] - 2015-11-20
+### Fixed
+- Fix meta information (`token.markup` and `token.info`) for autolink tokens.
+
+
+## [5.0.1] - 2015-10-30
+### Fixed
+- Improved tables compatibility with github, #120.
+
+
+## [5.0.0] - 2015-10-05
+### Changed
+- Internal API change. Due to new CM spec requirements, we had to update
+  internals. That should not touch ordinary users, but can affect some external
+  plugins. If you are plugin developper - see migration guide:
+  https://github.com/markdown-it/markdown-it/blob/master/docs/5.0_migration.md.
+- Updated CM spec compatibility to 0.22 (see list below).

+### Changed
+- Minor emphasis update to match CM spec 0.19.
+
+
+## [4.2.0] - 2015-04-21
+### Changed
+- Bumped [linkify-it](https://github.com/markdown-it/linkify-it) version to
+  1.1.0. Now links with IP hosts and without protocols are not linkified by
+  default, due possible collisions with some version numbers patterns (0.5.0.0).
+  You still can return back old behaviour by `md.linkify.set({ fuzzyIP: true })`.
+
+
+## [4.1.2] - 2015-04-19

+- Improved pipe chars support in table cells, #86 (thanks to @jbt).
+
+
+## [4.1.0] - 2015-03-31
+### Security

+  possible XSS. Version bumped, because features changed (formally). If you did
+  not used `data:` URLs, consider this version as 4.0.4 (no API changes).
+
+### Changed
+- Simplified link validator code. Now more easy to understand and to copy
+  into your projects for customization.
+
+
+## [4.0.3] - 2015-03-25

+
+
+### Simple
+
+```js
+// node.js, "classic" way:
+var MarkdownIt = require('markdown-it'),
+    md = new MarkdownIt();
+var result = md.render('# markdown-it rulezz!');
+
+// node.js, the same, but with sugar:
+var md = require('markdown-it')();
+var result = md.render('# markdown-it rulezz!');
+
+// browser without AMD, added to "window" on script load
+// Note, there is no dash in "markdownit".
+var md = window.markdownit();
+var result = md.render('# markdown-it rulezz!');
+```
+
+Single line rendering, without paragraph wrap:
+
+```js
+var md = require('markdown-it')();
+var result = md.renderInline('__markdown-it__ rulezz!');
+```
+
+
+### Init with presets and options
+
+(*) presets define combinations of active rules and options. Can be
+`"commonmark"`, `"zero"` or `"default"` (if skipped). See
+[API docs](https://markdown-it.github.io/markdown-it/#MarkdownIt.new) for more details.
+
+```js
+// commonmark mode
+var md = require('markdown-it')('commonmark');
+
+// default mode
+var md = require('markdown-it')();
+
+// enable everything
+var md = require('markdown-it')({
+  html: true,
+  linkify: true,
+  typographer: true
+});
+
+// full options list (defaults)
+var md = require('markdown-it')({
+  html:         false,        // Enable HTML tags in source
+  xhtmlOut:     false,        // Use '/' to close single tags (<br />).
+                              // This is only for full CommonMark compatibility.
+  breaks:       false,        // Convert '\n' in paragraphs into <br>
+  langPrefix:   'language-',  // CSS language prefix for fenced blocks. Can be
+                              // useful for external highlighters.
+  linkify:      false,        // Autoconvert URL-like text to links
+
+  // Enable some language-neutral replacement + quotes beautification
+  typographer:  false,
+
+  // Double + single quotes replacement pairs, when typographer enabled,
+  // and smartquotes on. Could be either a String or an Array.
+  //
+  // For example, you can use '«»„“' for Russian, '„“‚‘' for German,
+  // and ['«\xA0', '\xA0»', '‹\xA0', '\xA0›'] for French (including nbsp).
+  quotes: '“”‘’',
+
+  // Highlighter function. Should return escaped HTML,
+  // or '' if the source string is not changed and should be escaped externally.
+  // If result starts with <pre... internal wrapper is skipped.
+  highlight: function (/*str, lang*/) { return ''; }
+});
+```
+
+### Plugins load
+
+```js
+var md = require('markdown-it')()
+            .use(plugin1)
+            .use(plugin2, opts, ...)
+            .use(plugin3);
+```
+
+
+### Syntax highlighting
+
+Apply syntax highlighting to fenced code blocks with the `highlight` option:
+
+```js
+var hljs = require('highlight.js'); // https://highlightjs.org/
+
+// Actual default values
+var md = require('markdown-it')({
+  highlight: function (str, lang) {
+    if (lang && hljs.getLanguage(lang)) {
+      try {
+        return hljs.highlight(lang, str).value;
+      } catch (__) {}
+    }
+
+    return ''; // use external default escaping
+  }
+});
+```
+
+Or with full wrapper override (if you need assign class to `<pre>`):
+
+```js
+var hljs = require('highlight.js'); // https://highlightjs.org/
+
+// Actual default values
+var md = require('markdown-it')({
+  highlight: function (str, lang) {
+    if (lang && hljs.getLanguage(lang)) {
+      try {
+        return '<pre class="hljs"><code>' +
+               hljs.highlight(lang, str, true).value +
+               '</code></pre>';
+      } catch (__) {}
+    }
+
+    return '<pre class="hljs"><code>' + md.utils.escapeHtml(str) + '</code></pre>';
+  }
+});
+```
+
+### Linkify
+
+`linkify: true` uses [linkify-it](https://github.com/markdown-it/linkify-it). To
+configure linkify-it, access the linkify instance through `md.linkify`:
+
+```js
+md.linkify.tlds('.py', false);  // disables .py as top level domain
+```
+

+
+Embedded (enabled by default):
+
+- [Tables](https://help.github.com/articles/organizing-information-with-tables/) (GFM)
+- [Strikethrough](https://help.github.com/articles/basic-writing-and-formatting-syntax/#styling-text) (GFM)

+
+
+### Manage rules
+
+By default all rules are enabled, but can be restricted by options. On plugin
+load all its rules are enabled automatically.
+
+```js
+// Activate/deactivate rules, with curring
+var md = require('markdown-it')()
+            .disable([ 'link', 'image' ])
+            .enable([ 'link' ])
+            .enable('image');
+
+// Enable everything
+md = require('markdown-it')({
+  html: true,
+  linkify: true,
+  typographer: true,
+});
+```
+
+
+## Benchmark
+
+Here is the result of readme parse at MB Pro Retina 2013 (2.4 GHz):
+
+```bash
+make benchmark-deps
+benchmark/benchmark.js readme
+
+Selected samples: (1 of 28)
+ > README
+
+Sample: README.md (7774 bytes)
+ > commonmark-reference x 1,222 ops/sec ±0.96% (97 runs sampled)
+ > current x 743 ops/sec ±0.84% (97 runs sampled)
+ > current-commonmark x 1,568 ops/sec ±0.84% (98 runs sampled)
+ > marked x 1,587 ops/sec ±4.31% (93 runs sampled)
+```
+
+__Note.__ CommonMark version runs with [simplified link normalizers](https://github.com/markdown-it/markdown-it/blob/master/benchmark/implementations/current-commonmark/index.js)
+for more "honest" compare. Difference is ~ 1.5x.
+
+As you can see, `markdown-it` doesn't pay with speed for it's flexibility.
+Slowdown of "full" version caused by additional features not available in
+other implementations.

+- Alex Kocharin [github/rlidwka](https://github.com/rlidwka)
+- Vitaly Puzrin [github/puzrin](https://github.com/puzrin)
+
+_markdown-it_ is the result of the decision of the authors who contributed to
+99% of the _Remarkable_ code to move to a project with the same authorship but
+new leadership (Vitaly and Alex). It's not a fork.

+ **/
+
+/**
+ * new MarkdownIt([presetName, options])
+ * - presetName (String): optional, `commonmark` / `zero`
+ * - options (Object)
+ *
+ * Creates parser instanse with given config. Can be called without `new`.
+ *
+ * ##### presetName
+ *
+ * MarkdownIt provides named presets as a convenience to quickly
+ * enable/disable active syntax rules and options for common use cases.
+ *
+ * - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -
+ *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
+ * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -
+ *   similar to GFM, used when no preset name given. Enables all available rules,
+ *   but still without html, typographer & autolinker.
+ * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -
+ *   all rules disabled. Useful to quickly setup your config via `.enable()`.
+ *   For example, when you need only `bold` and `italic` markup and nothing else.
+ *
+ * ##### options:
+ *
+ * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!
+ *   That's not safe! You may need external sanitizer to protect output from XSS.
+ *   It's better to extend features via plugins, instead of enabling HTML.
+ * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags
+ *   (`<br />`). This is needed only for full CommonMark compatibility. In real
+ *   world you will need HTML output.
+ * - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`.
+ * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.
+ *   Can be useful for external highlighters.
+ * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.
+ * - __typographer__  - `false`. Set `true` to enable [some language-neutral
+ *   replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +
+ *   quotes beautification (smartquotes).
+ * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement
+ *   pairs, when typographer enabled and smartquotes on. For example, you can
+ *   use `'«»„“'` for Russian, `'„“‚‘'` for German, and
+ *   `['«\xA0', '\xA0»', '‹\xA0', '\xA0›']` for French (including nbsp).
+ * - __highlight__ - `null`. Highlighter function for fenced code blocks.
+ *   Highlighter `function (str, lang)` should return escaped HTML. It can also
+ *   return empty string if the source was not changed and should be escaped
+ *   externaly. If result starts with <pre... internal wrapper is skipped.
+ *
+ * ##### Example
+ *
+ * ```javascript
+ * // commonmark mode
+ * var md = require('markdown-it')('commonmark');
+ *
+ * // default mode
+ * var md = require('markdown-it')();
+ *
+ * // enable everything
+ * var md = require('markdown-it')({
+ *   html: true,
+ *   linkify: true,
+ *   typographer: true
+ * });
+ * ```
+ *
+ * ##### Syntax highlighting
+ *
+ * ```js
+ * var hljs = require('highlight.js') // https://highlightjs.org/
+ *
+ * var md = require('markdown-it')({
+ *   highlight: function (str, lang) {
+ *     if (lang && hljs.getLanguage(lang)) {
+ *       try {
+ *         return hljs.highlight(lang, str, true).value;
+ *       } catch (__) {}
+ *     }
+ *
+ *     return ''; // use external default escaping
+ *   }
+ * });
+ * ```
+ *
+ * Or with full wrapper override (if you need assign class to `<pre>`):
+ *
+ * ```javascript
+ * var hljs = require('highlight.js') // https://highlightjs.org/
+ *
+ * // Actual default values
+ * var md = require('markdown-it')({
+ *   highlight: function (str, lang) {
+ *     if (lang && hljs.getLanguage(lang)) {
+ *       try {
+ *         return '<pre class="hljs"><code>' +
+ *                hljs.highlight(lang, str, true).value +
+ *                '</code></pre>';
+ *       } catch (__) {}
+ *     }
+ *
+ *     return '<pre class="hljs"><code>' + md.utils.escapeHtml(str) + '</code></pre>';
+ *   }
+ * });
+ * ```
