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. - Changed type of `OpenXmlPackage.Package` to `DocumentFormat.OpenXml.Packaging.IPackage` instead of `System.IO.Packaging.Package` with a similar API surface - `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 - 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 (#1429) - Individual implementations of `OpenXmlPartReader` are available now for each package type (i.e. `WordprocessingDocumentPartReader`, `SpreadsheetDocumentPartReader`, `PresentationDocumentPartReader`), and the previous `TypedOpenXmlPartReader` has been removed. (#1403) - Reduced unnecessary target frameworks for packages besides DocumentFormat.OpenXml.Framework (#1471) - Changed some spelling issues for property names (#1463, #1444) - `Model3D` now represents the modified xml element tag name `am3d.model3d` (Previously `am3d.model3D`) - Removed `DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData.PivotCacheHasRichValuePivotCacheRichInfo` - Removed `DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData.RichDataPivotCacheGuid` - Removed unused `SchemaAttrAttribute` (#1316) - Removed unused `ChildElementInfoAttribute` (#1316) - Removed `OpenXmlSimpleType.TextValue`. This property was never meant to be used externally (#1316) - Removed obsolete validation logic from v1 of the SDK (#1316) - Removed obsoleted methods from 2.x (#1316) - Removed mutable properties on OpenXmlAttribute and marked as `readonly` (#1282) - Removed `OpenXmlPackage.Close` in favor of `Dispose` (#1373) - Removed `OpenXmlPackage.SaveAs` in favor of `Clone` (#1376) ## [2.20.0] ### Added - Added DocumentFormat.OpenXml.Office.Drawing.Y2022.ImageFormula namespace - Added DocumentFormat.OpenXml.Office.Word.Y2023.WordML.Word16DU namespace ### Changed - Marked `OpenXmlSimpleType.TextValue` as obsolete. This property was never meant to be used externally (#1284) - Marked `OpenXmlPackage.Package` as obsolete. This will be an implementation detail in future versions and won't be accessible (#1306) - Marked `OpenXmlPackage.Close` as obsolete. This will be removed in a later release, use Dispose instead (#1371) - Marked `OpenXmlPackage.SaveAs` as obsolete as it will be removed in a future version (#1378) ### Fixed - Fixed incorrect file extensions for vbaProject files (#1292) - Fixed incorrect file extensions for ImagePart (#1305) - Fixed incorrect casing for customXml (#1351) - Fixed AddEmbeddedPackagePart to allow correct extensions for various content types (#1388) ## [2.19.0] - 2022-12-14 ### Added - .NET 6 target with support for trimming (#1243, #1240) - Added DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData namespace - Added DocumentFormat.OpenXml.Office.PowerPoint.Y2019.Main.Command namespace - Added DocumentFormat.OpenXml.Office.PowerPoint.Y2022.Main.Command namespace - Added Child RichDataPivotCacheGuid to DocumentFormat.OpenXml.Office2010.Excel.PivotCacheDefinition ### Fixed - Removed reflection usage where possible (#1240) - Fixed issue where some URIs might be changed when cloning or creating copy (#1234) - Fixed issue in FlatOpc generation that would not read the full stream on .NET 6+ (#1232) - Fixed issue where restored relationships wouldn't load correctly (#1207) ## [2.18.0] 2022-09-06 ### Added - Added DocumentFormat.OpenXml.Office.SpreadSheetML.Y2021.ExtLinks2021 namespace (#1196) - Added durableId attribute to DocumentFormat.OpenXml.Wordprocessing.NumberingPictureBullet (#1196) - Added few base classes for typed elements, parts, and packages (#1185) ### Changed - Adjusted LICENSE.md to conform to .NET Foundation requirements (#1194) - Miscellaneous changes for better perf for internal services ## [2.17.1] - 2022-06-28 ### Removed - Removed the preview namespace DocumentFormat.OpenXml.Office.Comments.Y2020.Reactions because this namespace will currently create invalid documents. ### Fixed - Restored the PowerPointCommentPart relationship to PresentationPart. ### Deprecated - The relationship between the PowerPointCommentPart and the PresentationPart is deprecated and will be removed in a future version. ## [2.17.0] - Unreleased ### Added - Added DocumentFormat.OpenXml.Office.Comments.Y2020.Reactions namespace (#1151) - Added DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotVersionInfo namespace (#1151) ### Fixed - Moved PowerPointCommentPart relationship to SlidePart (#1137) ### Updated - Removed public API analyzers in favor of EnablePackageValidation (#1154) ## [2.16.0] - 2022-03-14 ### Added - Added method `OpenXmlPart.UnloadRootElement` that will unload the root element if it is loaded (#1126) ### Updated - Schema code generation was moved to the SDK project using C# code generators Thanks to the following for their contribution: @f1nzer ## [2.15.0] - 2021-12-16 ### Added - Added samples for strongly typed classes and Linq-to-XML in the `./samples` directory (#1101, #1087) - Shipping additional libraries for some additional functionality in `DocumentFormat.OpenXml.Features` and `DocumentFormat.OpenXml.Linq`.
