3.1.2

• SECURITY FIX: update dot-prop to 5.2.0

Breaking changes

• Unfortunately, due to fixing the vulnerability, the minimum supported version of the Node.js is 8.

3.1.1

• Fix: typescript definitions weren't in the published package.

3.1.0

• Fixed numerous bugs in attribute nodes relating to the handling of comments
  and whitespace. There's significant changes to attrNode.spaces and attrNode.raws since the 3.0.0 release.
• Added Attribute#offsetOf(part) to get the offset location of
  attribute parts like "operator" and "value". This is most
  often added to Attribute#sourceIndex for error reporting.

3.0.0

Breaking changes

• Some tweaks to the tokenizer/attribute selector parsing mean that whitespace
  locations might be slightly different to the 2.x code.
• Better attribute selector parsing with more validation; postcss-selector-parser
  no longer uses regular expressions to parse attribute selectors.
• Added an async API (thanks to @jacobp100); the default process API is now
  async, and the sync API is now accessed through processSync instead.
• process() and processSync() now return a string instead of the Processor
  instance.
• Tweaks handling of Less interpolation (thanks to @jwilsson).
• Removes support for Node 0.12.

Other changes

• ast() and astSync() methods have been added to the Processor. These
  return the Root node of the selectors after processing them.
• transform() and transformSync() methods have been added to the
  Processor. These return the value returned by the processor callback
  after processing the selectors.
• Set the parent when inserting a node (thanks to @chriseppstein).
• Correctly adjust indices when using insertBefore/insertAfter (thanks to @tivac).
• Fixes handling of namespaces with qualified tag selectors.
• process, ast and transform (and their sync variants) now accept a
  postcss rule node. When provided, better errors are generated and selector
  processing is automatically set back to the rule selector (unless the updateSelector option is set to false.)
• Now more memory efficient when tokenizing selectors.

Upgrade hints

The pattern of:

rule.selector = processor.process(rule.selector).result.toString();

is now:

processor.processSync(rule)

2.2.3

• Resolves an issue where the parser would not reduce multiple spaces between an
  ampersand and another simple selector in lossy mode (thanks to @adam-26).

2.2.2

• No longer hangs on an unescaped semicolon; instead the parser will throw
  an exception for these cases.

2.2.1

• Allows a consumer to specify whitespace tokens when creating a new Node
  (thanks to @Semigradsky).

2.2.0

• Added a new option to normalize whitespace when parsing the selector string
  (thanks to @adam-26).

2.1.1

• Better unquoted value handling within attribute selectors
  (thanks to @evilebottnawi).

2.1.0

• Added: Use string constants for all node types & expose them on the main
  parser instance (thanks to @Aweary).

 2.0.0

This release contains the following breaking changes:

• Renamed all eachInside iterators to walk. For example, eachTag is now
  walkTags, and eachInside is now walk.
• Renamed Node#removeSelf() to Node#remove().
• Renamed Container#remove() to Container#removeChild().
• Renamed Node#raw to Node#raws (thanks to @davidtheclark).
• Now parses & as the nesting selector, rather than a tag selector.
• Fixes misinterpretation of Sass interpolation (e.g. #{foo}) as an
  id selector (thanks to @davidtheclark).

and;

• Fixes parsing of attribute selectors with equals signs in them
  (e.g. [data-attr="foo=bar"]) (thanks to @montmanu).
• Adds quoted and raw.unquoted properties to attribute nodes
  (thanks to @davidtheclark).

1.3.3

• Fixes an infinite loop on ) and ] tokens when they had no opening pairs.
  Now postcss-selector-parser will throw when it encounters these lone tokens.

 1.3.2

• Now uses plain integers rather than str.charCodeAt(0) for compiled builds.

1.3.1

• Update flatten to v1.x (thanks to @shinnn).

1.3.0

• Adds a new node type, String, to fix a crash on selectors such as
  foo:bar("test").

1.2.1

• Fixes a crash when the parser encountered a trailing combinator.

1.2.0

• A more descriptive error is thrown when the parser expects to find a
  pseudo-class/pseudo-element (thanks to @ashelley).
• Adds support for line/column locations for selector nodes, as well as a
  Node#sourceIndex method (thanks to @davidtheclark).

1.1.4

• Fixes a crash when a selector started with a > combinator. The module will
  now no longer throw if a selector has a leading/trailing combinator node.

1.1.3

• Fixes a crash on @ tokens.

1.1.2

• Fixes an infinite loop caused by using parentheses in a non-pseudo element
  context.

1.1.1

• Fixes a crash when a backslash ended a selector string.

1.1.0

• Adds support for replacing multiple nodes at once with replaceWith
  (thanks to @jonathantneal).
• Parser no longer throws on sequential IDs and trailing commas, to support
  parsing of selector hacks.

1.0.1

• Fixes using insertAfter and insertBefore during iteration.

1.0.0

• Adds clone and replaceWith methods to nodes.
• Adds insertBefore and insertAfter to containers.
• Stabilises API.

0.0.5

• Fixes crash on extra whitespace inside a pseudo selector's parentheses.
• Adds sort function to the container class.
• Enables the parser to pass its input through without transforming.
• Iteration-safe each and eachInside.

0.0.4

• Tidy up redundant duplication.
• Fixes a bug where the parser would loop infinitely on universal selectors
  inside pseudo selectors.
• Adds length getter and eachInside, map, reduce to the container class.
• When a selector has been removed from the tree, the root node will no longer
  cast it to a string.
• Adds node type iterators to the container class (e.g. eachComment).
• Adds filter function to the container class.
• Adds split function to the container class.
• Create new node types by doing parser.id(opts) etc.
• Adds support for pseudo classes anywhere in the selector.

0.0.3

• Adds next and prev to the node class.
• Adds first and last getters to the container class.
• Adds every and some iterators to the container class.
• Add empty alias for removeAll.
• Combinators are now types of node.
• Fixes the at method so that it is not an alias for index.
• Tidy up creation of new nodes in the parser.
• Refactors how namespaces are handled for consistency & less redundant code.
• Refactors AST to use nodes exclusively, and eliminates excessive nesting.
• Fixes nested pseudo parsing.
• Fixes whitespace parsing.

0.0.2

• Adds support for namespace selectors.
• Adds support for selectors joined by escaped spaces - such as .\31\ 0.

0.0.1

• Initial release.
