• Fix for https://github.com/dart-lang/sdk/issues/60553, PrefixElement2.

v7.4.1

• Restore InstanceElement.augmented getter.
  This API was removed in 7.4.0 under the assumption that its removal would
  not be a breaking change, because it was marked as @experimental.
  But it turns out that some clients had been published to pub that relied
  on it. So, these APIs were restored, and implemented on top of Element2.

v7.4.0

• Deprecated element model V1.
  See migration guide.

v7.3.0

• Add flags optional named parameter to FeatureSet.latestLanguageVersion().

v6.11.0

• Un-deprecated LibraryElement.exportedLibraries.
• Un-deprecated LibraryElement.importedLibraries.

v6.10.0

• Deprecated LibraryElement.accessibleExtensions, use
  CompilationUnitElement.accessibleExtensions instead.
• Deprecated LibraryElement.exportedLibraries.
• Deprecated LibraryElement.importedLibraries.
• Deprecated LibraryElement.isBrowserApplication.
• Deprecated LibraryElement.libraryExports,
  use CompilationUnitElement.libraryExports instead.

• Deprecated File.createSource(), it violates levels of abstraction.
  You can get Source instances from AnalysisResults.

v6.6.0

• Stop exporting src/file_system/file_system.dart
  from file_system/file_system.dart.
• Deprecated package:analyzer/src/source/source_resource.dart,
  import package:analyzer/source/file_source.dart instead.
• Deprecated exports from package:analyzer/src/source/source.dart,
  import package:analyzer/source/source.dart instead.

v6.5.2

• Updated constraints macros: '>=0.1.2-0 <0.1.3'.

v6.5.1

• Updated constraints macros: '>=0.1.1-0 <0.1.2'.

v6.5.0

• Deprecated LibraryElement.toLegacyTypeIfOptOut.
• Deprecated LibraryElement.toLegacyElementIfOptOut.
• Deprecated LibraryElement.isNonNullableByDefault.
• Deprecated InterfaceElement.lookUpGetter, InterfaceElement.lookUpMethod,
  and InterfaceElement.lookUpSetter.
• Fixed GeneralizingAstVisitor.visitNamedType to invoke visitTypeAnnotation.
• Deprecated PropertyInducingElement get variable in PropertyAccessorElement,
  use PropertyInducingElement? get variable2 instead.
  The reason for this is that when the property accessor is an augmentation
  without the corresponding declaration, there is no corresponding variable.
• Deprecated ExtensionDeclaration.onKeyword and extendedType.
  Use ExtensionOnClause? get onClause instead.
  Extension augmentations are not allowed to have onClause.
• Deprecated OnClause, use MixinOnClause instead.

• Support new meta annotation: @mustBeConst.
• Support new meta TargetKinds: constructor, directive, enumValue, and
  typeParameter.
• Fix for accessing constants from extension type, when import prefixed.
• Deprecated AstNode.getProperty and AstNode.setProperty. Clients who need
  the ability to add arbitrary decorations to AST nodes can achieve the same
  effect using Dart's built-in
  Expando class.

v6.4.1

• Patch for crash in ffi_verifier.

v6.3.0

• Updated the current language version to 3.3.
• Removed generated ConstantEvaluator.

v6.2.0

• Improvements for extension types.
• Heap usage improvements.

v6.1.0

• Added InstanceElement, a super-interface for InterfaceElement
  and ExtensionElement.
• Added TypeSystem.greatestLowerBound.

v6.0.0

• Remove deprecated declaredElement2 from AST.
• Remove deprecated element2 from AST.
• Remove deprecated name2 from AST.
• Remove deprecated FunctionBody.isPotentiallyMutatedInClosure.
• Remove deprecated extensionName, staticElement from ExtensionOverride.
• Remove deprecated name from NamedType.

v5.13.0

• InvalidType is now used when types or property cannot be resolved.
  Previously DynamicType was used.
• Fixed #​52352, #​52360, #​52362, #​35828, #​26710, #​52313, #​52327.

v5.12.0

• Deprecated DartType.isDynamic, use is DynamicType instead.
• Updated NamedType to use importPrefix and name2 token.
  The deprecated name node is still visited in this version, but will stop
  in the next major version.
• Updated ExtensionOverride to use importPrefix and name token.
  The deprecated extensionName node is still visited in this version, but
  will stop in the next major version.
• Deprecated the default AnalysisError constructor, use tmp constructor,
  with names formal parameters. Theoretically no clients should use either,
  but practically there are two uses currently.
• Added InvalidType, used when a named type cannot be resolved, or a
  property cannot be resolved, etc. Previously DynamicType was used.
  In the future DynamicType will be used only when specified explicitly,
  or a property is resolved against a dynamic target. The clients should
  prepare by checking also for InvalidType in addition to DynamicType.

v5.11.1

• Restore previously published finalKeyword, interfaceKeyword and
  sealedKeyword of MixinElement. We added them preliminary while
  working on the class modifiers feature, but eventually decided to remove.
  https://github.com/dart-lang/sdk/issues/521592159 for details.

v5.11.0

• Removed @experimental from AST nodes and elements for records and patterns.
• Deprecated IfStatement.condition, use expression instead.
• Added NamedType.importPrefix, NamedType.name2, and NamedType.element.
  Deprecated NamedType.name. Currently Identifier is an expression, and
  an expression as a name of a type does not make sense. So, instead we model
  it as a name token, the Element that it references, and an optional import
  library prefix reference.

v5.10.0

• Added DartType.isDartCoreType.

v5.9.0

• Deprecated FunctionBody.isPotentiallyMutatedInClosure, not used by clients.
• Fix for FunctionBody.isPotentiallyMutatedInScope and pattern assignment.

v5.8.0

• Deprecated DartType.isVoid, use is VoidType instead.
• records, patterns, and class-modifiers features enabled by default.

v5.7.1

• Require SDK >=2.19.0 <3.0.0 to use PathNotFoundException from dart:io.

v5.6.0

• Fixes for patterns parsing.
• Implemented DartPattern.precedence.

v5.5.0

• Rename RecordPatternFieldName to PatternFieldName.

v5.4.0

• Bug fixes: 50660

v5.3.1
