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.
