• Added check to only seek on packages where it is supported (#​1644)
• If a malformed URI is encountered, the exception is now the same as v2.x (OpenXmlPackageException with an inner UriFormatException) (#​1644)

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@)
• Introduce equality comparers for OpenXmlElement (#​1476)
• IFeatureCollection can now be enumerated and has a helpful debug view to see what features are registered (#​1452)
• Add mime types to part creation (#​1488)
• DocumentFormat.OpenXml.Office.PowerPoint.Y2023.M02.Main namespace
• DocumentFormat.OpenXml.Office.PowerPoint.Y2022.M03.Main namespace

Changed

• When validation finds incorrect part, it will now include the relationship type rather than a class name
• IDisposableFeature is now a part of the framework package and is available by default on a package or part.

Breaking Changes

• .NET Standard 1.3 is no longer a supported platform. .NET Standard 2.0 is the lowest .NET Standard supported.
• 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.
• 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)

3.0.0-beta3

Added

• Introduce equality comparers for OpenXmlElement (#​1476)
• IFeatureCollection can now be enumerated and has a helpful debug view to see what features are registered (#​1452)
• Add mime types to part creation (#​1488)

Breaking changes

• Changed some spelling issues for property names (#​1463, #​1444)

3.0.0-beta2

Breaking Changes

• 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.

3.0.0-beta1

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@)

• 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
