**Release created on: 30.12.2022 - 08:19:24**

New Features

* Dependency graph in `Design` for packages, contexts referenced from design units.
* New `_dependencyGraph` field in `Design`.
* New `_dependencyVertex` field in `DesignUnit`.
* New `CreateDependencyGraph` method on `Design`.

**Release created on: 26.12.2022 - 21:11:29**

New Features

* Converted many existing symbol classes to new symbol classes deriving from `Name` and `NewSymbol`.
This simplifies the usage of symbols, as names in VHDL are already very close to symbols.
⚠️ `NewSymbol` will be renamed to `Symbol` or `SymbolMixin` once all symbols are converted to the new style.
* `LibraryReferenceSymbol`
* `PackageReferenceSymbol`
* `PackageMembersReferenceSymbol`
* `AllPackageMembersReferenceSymbol`
* `ContextReferenceSymbol`
* `EntitySymbol`
* `ArchitectureSymbol`
* `PackageSymbol`
* Named entities and new-style symbols now provide a `NormalizedIdentifier` property.
* Implemented more analyze methods on Design:
* `LinkPackageReferences`
* `LinkContextReferences`
* Added `_references`, `_contextReferences` and `_referenced***` fields to `Context` class.
* Added predefined flag groups to `PossibleReference`.
* Added `_referenced***` fields to `DesignUnitWithContextMixin` class.
* Added `DesignUnits` flag for filtering in `IterateDesignUnits`.

Changes

* Changed `PossibleReference` from `IntEnum` to `Flag`.
* Merged parameters `libraryReferences`and `packageReferences` of class `Context` to new parameter `references`.
* A package body now doesn't except an identifier for its name, but a PackageSymbol.
* Improved analyze methods:
* `LinkLibraryReferences`
* `LinkArchitectures`
* `LinkPackageBodies`
* Using `...Identifier` instead of `...Name` in variables and parameters for a name of an entity. This identifier variable is normalized. In exceptions, `...Identifier` is used to print the original name without normalization.
* Improved predefined libraries and packages `std.standard`, etc.


Bug Fixes

* Added missing initializer for `IndexedName`.
* Fixed how flag values are combined: `+` → `|`
* Fixed example code in README.

**Release created on: 23.12.2022 - 22:38:50**

New Features

* Added `Document` property to `DesignUnit`.
* Added `LibraryReferenceSymbol`, `PackageReferenceSymbol` and `ContextReferenceSymbol`.
* Added new packages `std` and `ieee` containing pre-defined VHDL libraries and VHDL packages.
* Added `LoadStdLibrary` and `LoadIEEELibrary` to `Design`.
* Added `IterateDesignUnits` generator on `Design` and `Library`.
* Implemented various analyze methods on `Design`:
* `LinkLibraryReferences`
* `LinkArchitectures`
* `LinkPackageBodies`
* Added `_Add***` methods to `Document`.
* Added `DesignUnits`, `VerificationUnits`, `VerificationProperties` and `VerificationModes` properties to `Document`.

Changes

* Moved classes:
* `pyVHDLModel.SyntaxModel.Name` → `pyVHDLModel.Name`
* `pyVHDLModel.SyntaxModel.Symbol` → `pyVHDLModel.Symbol`
* `pyVHDLModel.SyntaxModel.Reference` → `pyVHDLModel.Reference`
* `pyVHDLModel.SyntaxModel.LibraryClause` → `pyVHDLModel.LibraryClause`
* `pyVHDLModel.SyntaxModel.UseClause` → `pyVHDLModel.UseClause`
* `pyVHDLModel.SyntaxModel.ContextReference` → `pyVHDLModel.ContextReference`
* Property `PrimaryUnit.Library` uses it's own private field `_library` instead of `_parent`, so `_parent` can be used to refer to the document a design unit is in.
* Improved `EntitySymbol`, `ArchitectureSymbol`, `PackageSymbol`.
* Improved `GetLibrary` in `Design`.
* Improved `AddDocument` in `Library`.
* Changed almost all internal lists in `Library` and `Document` to dictionaries for quick name lookups.
* Enabled CI job Windows + Python 3.11 again.
* Bumped dependencies.
* Updated MAKEFILE for Sphinx documentation.

Bug Fixes

* Fixed usage of Names vs. Symbols.
