# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).

## [3.0.0]

### Added
- Packages can now be saved on .NET Core and .NET 5+ if constructed with a path or stream (#1307).
- Packages can now support malformed URIs (such as relationships with a URI such as `mailto:person@`)

### Changed
- When validation finds incorrect part, it will now include the relationship type rather than a class name

### Removed
- .NET Standard 1.3 is no longer a supported platform. .NET Standard 2.0 is the lowest .NET Standard supported.
- Removed unused `SchemaAttrAttribute`
- Removed unused `ChildElementInfoAttribute`
- Removed `OpenXmlSimpleType.TextValue`. This property was never meant to be used externally
- Removed obsolete validation logic from v1 of the SDK
- Removed obsoleted methods from 2.x
- Removed mutable properties on OpenXmlAttribute and marked as `readonly`
- Removed `OpenXmlPackage.Close` in favor of Dispose (#1373)
- Removed `OpenXmlPackage.SaveAs` in favor of Clone (#1376)
- Removed `OpenXmlPackage.Package` property. A `OpenXmlPackage` is now backed by an internal (for now) type `IPackage` instead of `System.IO.Packaging.Package`

### Breaking change
- Core infrastructure is now contained in a new package DocumentFormat.OpenXml.Framework. Typed classes are still in DocumentFormat.OpenXml. This means that you may reference DocumentFormat.OpenXml and still compile the same types, but if you want a smaller package, you may rely on just the framework package.
- `EnumValue<T>` now is used to box a struct rather than a `System.Enum`. This allows us to enable behavior on it without resorting to reflection
- Methods on parts to add child parts (i.e. `AddImagePart`) are now implemented as extension methods off of a new marker interface `ISupportedRelationship<T>`
- Part type info enums (i.e. `ImagePartType`) is no longer an enum, but a static class to expose well-known part types as structs. Now any method to define a new content-type/extension pair can be called with the new `PartTypeInfo` struct that will contain the necessary information.
- `OpenXmlPackage.CanSave` is now an instance property (#1307)
- Removed `OpenXmlSettings.RelationshipErrorHandlerFactory` and associated types and replaced with a built-in mechanism to enable this
- `IdPartPair` is now a readonly struct rather than a class
- `IDisposableFeature` is now a part of the framework package and is available by default on a package or part.
- Renamed PartExtensionProvider to IPartExtensionFeature and reduced its surface area to only two methods (instead of a full Dictionary<,>). The property to access this off of OpenXmlPackage has been removed, but may be accessed via `Features.Get<IPartExtensionFeature>()` if needed.
- `OpenXmlPart`/`OpenXmlContainer`/`OpenXmlPackage` and derived types now have internal constructors (these had internal abstract methods so most likely weren't subclassed externally)
- `OpenXmlElementList` is now a struct that implements `IEnumerable<OpenXmlElement>` and `IReadOnlyList<OpenXmlElement>` (where available)
- Individual implementations of `OpenXmlPartReader` are available now for each package type (i.e. `WordprocessingDocumentPartReader`, `SpreadsheetDocumentPartReader`, `PresentationDocumentPartReader`), and the previous `TypedOpenXmlPartReader` has been removed.

## [2.20.0]

### Changed
