v4.1.0

• Move to analyzer 2.7.0. (#2845)
• The library interface is now explicitly marked as experimental via meta.
• Experimental feature: HTML output from markdown rendering, {@tool} and
  {@inject-html} is sanitized when hidden option --sanitize-html is passed.
• Refactor of ModelElement and ElementType constructors. Technically breaking
  but known users of the API do not attempt to construct these types by hand.
  (#2828, #2829)
• Move to recommended set of hints in linter and correct some small errors
  in regexps. (#2833)

v4.0.0

4.0.0

• BREAKING CHANGE: Refactors to support NNBD and adapt to new analyzer
  changes are technically semver breaking. If you make extensive use of
  the documentationComment getter on ModelElement or other deep
  structural elements in dartdoc or custom templates, they could break
  dependent code. (#2819, #2818, #2817, #2806, #2798)
• BREAKING CHANGE: Remove a large number of long-standing deprecated
  symbols in dartdoc. (#2821)
• Fix a problem where certain comment reference strings could
  crash the parser. (#2813, #2808)
• Fix an assert in canonicalization for enums. (#2812)

v3.1.0

• This version supports the Dart language feature constructor tearoffs,
  pending completion by other tools.
• Allow embedded type parameters in comment references. (#2772)
• Add testing for constructor tearoff constant rendering. (#2780)
• Do not crash on package not found, instead provide a more useful
  explanation for users. (#2781, #2778)
• --allow-warnings-in-packages no longer also applies to errors.
  The --allow-errors-in-packages flag should now work as intended.
  (#2785)
• Some additional deprecations preparing for NNBD. (#2784)

v3.0.0

• BREAKING CHANGE: Refactor of Class, Enum, and Mixin types result in some
  deleted interfaces in templates and a change in class hierarchy. (#2770)
• The experimental 'constructor-tearoffs' feature has been partially
  implemented in dartdoc and should work in simple cases. (#2655, #2770,
  #2768, #2766, #2763).
• BREAKING CHANGE: The old lookup code has been deleted, along with the
  --no-enhanced-reference-lookup flag. (#2765)
• Deprecated uses of pub have been removed. (#2764)
• Some internal refactors to support NNBD migration.

v2.0.0

• BREAKING CHANGE: changes to dartdoc options API
  to prepare for NNBD migration (#2745, #2744).
• Fix unbound type reference in extension method comment
  reference creating a null dereference (#2741, #2740)
• Update to analyzer 2.0. (#2734)
• Fix comment references on generic typedefs in new
  lookup code. (#2755, #2756)

v1.0.2

• Fix where extensions header in library sidebar linked to the
  wrong place. (#2717)
• Fix concurrency issues in tool execution and parallelize
  optimally for the number of cores in the system. (#2730)
• Display message if tool snapshotting fails. (#2731)

v1.0.1

• Fix several issues with new type hierarchy. (#2714, #2721)
• Allow code in "diff" language to be syntax highlighted. (#2718)

v1.0.0

1.0.0

• BREAKING CHANGE: Enable the enhanced lookups by default.
  Some formerly invalid doc references will no longer be
  ignored and now generate warnings, and some ambiguous
  references may change where they point. As a fallback,
  allow a --no-enhanced-reference-lookup but this will
  be removed soon so please file bugs if you need to use this.
  (#2705)
• Use the Mustachio AOT compiler for default templates. (#2677)
• Unhide the --format option so users can discover
  the markdown support (#2703)
• Internal refactors of tool/dartdoc code. (#2686, 2669)
• Many changes to improve compliance on the new lookup code.
  (#2709, #2707, #2706, #2703, #2702, #2700, #2691, #2687, #2684,
  #2682, #2673, #2672, #2671)
• Update favicon to match dart.dev. (#2681)
• Runtime and AOT renderer fixes for Mustachio. (#2697,
  #2674, #2676, #2670, #2697)
• Fix several problems with head analyzer. (#2680, #2687)
• The favicon has been updated to match dart.dev. (#2681)
• A variety of internal refactoring changes.

v0.45.0

• BREAKING CHANGE: Custom templates using some obscure
  getters of modelType may no longer function (returnElement
  and others not used in standard templates). (#2665)
• BREAKING CHANGE: Implicit Future detection, where an
  asynchronous function without a declared return type had
  its return type listed as Future, is no more. Those
  functions now show a dynamic return type. (#2665)
• Fix a problem with enum field location calculations.
  (#2660, #2659)
• Support for AOT compilation of templates added to Mustachio,
  but not yet enabled. (#2664, #2651)
• Some additional new lookup code implementation and testing.

v0.44.0

• BREAKING CHANGE: Add support for generic metadata rendering in
  typedefs. (#2649, #2654). This changes how typedefs are rendered
  so that they all appear as new generic typedefs. This means
  that typedefs can no longer share the _callable templates
  and have their own implementations.
• Add query strings to static assets to ensure they refresh in
  browsers on changes. (#2646)
• Change the comment reference unparser to use analyzer AST tokens
  instead of file access. (#2642)
