<!--## Unreleased-->

## [2.0.0-alpha.33] - 2017-03-14

* Populate `astNode` on `PolymerElementMixin`.

## [2.0.0-alpha.32] - 2017-03-13

* Added options argument for Analyzer's experimental `_fork` method, supporting individual property overrides.
* Parse observers and computed functions in Polymer declarations. Warn on parse errors, or using the wrong syntax (e.g. function calls in `observer`, not a function call in `computed`).
* Correctly scan the `customElements.define(MyClass.is, MyClass)` pattern.

## [2.0.0-alpha.31] - 2017-03-07

* Clean up method descriptions

## [2.0.0-alpha.30] - 2017-03-03

* Fix typo in package.json.

## [2.0.0-alpha.29] - 2017-03-03

* Added a `_fork` method to Analyzer.
* Support for method detection on polymer elements and mixins via the new `methods` property.
* Support for function analysis (namespaced functions only for now, via the `@memberof` jsdoc tag).
* Track privacy on elements, mixins, properties, methods, and functions on namespaces.
  * replaced `private: boolean` with `privacy: 'public' | 'private' | 'protected'`
  * respects `@public` `@private` and `@protected` in jsdoc
  * considers one leading underscore to be protected, and two to be private
  * one trailing underscore is private (closure style)
* Track inheritance source for mixin and element members.
* Exported all public api through the package's `main` file, so that all public api can be accessed directly off of the object returned by `require('polymer-analyzer')` without the need to add imports into `polymer-analyzer/lib/whatever`.
* Track mixins on mixins and emit them in the Analysis. We don't mix properties into mixins yet.

## [2.0.0-alpha.28] - 2017-02-24
* Support for `@memberof` jsdoc tag
* Fix bad mixin descriptions


### Fixed
* PackageUrlResolver encodes URIs returned from `resolve` method.
* Support new properties/observers getters in Polymer 2.0 elements

## [2.0.0-alpha.27] - 2017-02-24

### Added
* Support for `@extends` and `@namespace` jsdoc tags
* Analyze inherited members for class-based elements annotated with `@extends`
* New Namespace and Reference features
* Mixins and namespaces are included in metadata export
* Ability to generate metadata for a package and filter exported metadata
* Analyze Polymer 2.0 elements that override observedAttributes

### Fixed
* Analyzer will not attempt to load or add warnings for imports which can not be resolved by its urlResolver.
* Protocol-less URLs such as `//host/path` are properly handled instead of treated as absolute paths.
* Infer tagnames from the static `is` getter.
* Unified Polymer and Vanilla element scanners

## [2.0.0-alpha.26] - 2017-02-22
* Fix issue with file missing from package.json "files" array.

## [2.0.0-alpha.25] - 2017-02-22

### Added
* Polymer 2.0 mixin scanner
* [polymer] Parse polymer databinding expressions.
  Give accurate warnings on parse errors.

## [2.0.0-alpha.24] - 2017-02-14

### Added
* HTML Documents now include a `baseUrl` property which is properly resolved
  from a `<base href="...">` tag, when present.
* Add `localIds` to `PolymerElement`, tracking elements in its template by their id attributes.

### Fixed

* [Polymer] Better handle unexpected behavior reference syntax.

## [2.0.0-alpha.23] - 2017-02-10

### Added

* [BREAKING] All methods on Document no longer return results from dependencies, but do return results from inline documents. Added a queryOptions param to all query methods to specify getting results from dependencies.
* [BREAKING] All methods on both Document and Package no longer return results from external code. Must specify `externalPackages: true` to get features from code outside the current package.

### Fixed

* Properly cache warning for incorrect imports or when failing parsing an import.
* Notice references to elements within `<template>` tags.

## [2.0.0-alpha.22] - 2017-01-13

### Fixed

* Do not complain about ES6 module syntax, but store enough information that we can warn about referencing modules as scripts.


## [2.0.0-alpha.21] - 2016-12-22

### Added
* Add an analyzePackage() method, for getting a queryable representation of everything in a package.

### Fixed
* Fix a deadlock when there are concurrent analysis runs of cyclic graphs.

## [2.0.0-alpha.20] - 2016-12-19

### Added
* [Polymer] Extract 'listeners' from 1.0-style declarations.
* [Polymer] Extract pseudo elements from HTML comments

### Fixed
* Fix a class of race conditions and cache invalidation errors that can occur when there are concurrent analysis runs and edits to files.


## [2.0.0-alpha.19] - 2016-12-12

### Added
* Add `changeEvent` to `Attribute`.

### Fixed
* Bump JS parser up to parse ES2017 (ES8).
* [Polymer] Property descriptors are allowed to be just a type name, like `value: String`.

## [2.0.0-alpha.18] - 2016-11-21

### Fixed
* [Polymer] A number of fixes around warnings when resolving behaviors
  * Warn, don't throw when a behavior is declared twice.
  * Warn when there's a problem mixing behaviors into other behaviors, the same way that we warn when mixing behaviors into elements.

* Fix some bugs with recursive and mutually recursive imports.

### Added
* Add `slots` to `Element`.

## [2.0.0-alpha.17] - 2016-10-28 - [minor]

### Added

* Add a new default scanner for custom element references in html.
  * Also adds a non-default scanner for all element references in html.
  * Known bug: does not find element references inside of `<template>` elements.

## [2.0.0-alpha.15] - 2016-10-15

### Changed

* (polymer) - computed properties are implicitly readOnly.

* (editor service) - Greatly improve `getLocationForPosition` for determining the meaning of text at an HTML source location. Presently used for doing autocompletions.
  * Handles the contents of `<template>` elements.
  * Distinguishes attribute names from values.
  * Understands when text is inside a comment, inline style, and inline script.
  * Better handle many, many edge cases.
