This may cause changes in what errors are reported. ### Fixed - Fixed some documentation inconsistencies (#582) - Fixed `ToFlatOpcDocument`, `ToFlatOpcString`, `FromFlatOpcDocument`, and `FromFlatOpcString` to correctly process Alternative Format Import Parts, or "altChunk parts" (#659) ## Version 2.9.1 - 2019-03-13 ### Changed - Added a workaround for a .NET Native compiler issue that doesn't support calling Marshal.SizeOf<T> with a struct that contains auto-implemented properties (#569) - Fixed a documentation error (#528) ## Version 2.9.0 - 2018-06-08 ### Added - `ListValue` now implements `IEnumerable<T>` (#385) - Added a `WebExtension.Frozen` and obsoleted misspelled `Fronzen` property (#460) - Added an `OpenXmlPackage.CanSave` property that indicates whether a platform supports saving without closing the package (#468) - Simple types (except `EnumValue` and `ListValue`) now implement `IComparable<T>` and `IEquatable<T>` (#487) ### Changed - Removed state that was carried in validators that would hold onto packages when not in use (#390) - `EnumSimpleType` parsing was improved and uses less allocations and caches for future use (#408) - Fixed a number of spelling mistakes in documentation (#462) - When calling `OpenXmlPackage.Save` on .NET Framework, the package is now flushed to the stream (#468) - Fixed race condition while performing strict translation of attributes (#480) - Schema data for validation uses a more compact format leading to a reduction in dll size and performance improvements for loading (#482, #483) - A number of APIs are marked as obsolete as they have simple workarounds and will be removed in the next major change - Fixed some constraint values for validation that contained Office 2007, even when it was only supported in later versions - Updated `System.IO.Packaging` to 4.5.0 which fixes some issues on Xamarin platforms as well as minimizes dependencies on .NET Framework ## Version 2.8.1 - 2018-01-03 ### Changed - Corrected package license file reference to show updated MIT License ## Version 2.8.0 - 2017-12-28 ### Added - Default runtime directive for better .NET Native support. ### Changed - Fixed part saving to be encoded with UTF8 but no byte order mark. This caused some renderers to not be able to open the generated document. - Fixed exceptions thrown when errors are encountered while opening packages to be consistent across platforms. - Fixed issue on Mono platforms using System.IO.Packaging NuGet package (Xamarin, etc) when creating a document. - Fixed manual saving of a package when autosave is false. - Fixed schema constraint data and standardized serialization across platforms. - Upgraded to `System.IO.Packaging` version 4.4.0 which fixes some consistency with .NET Framework in opening packages. ## Version 2.7.2 - 2017-06-06 ### Added - Package now supports .NET 3.5 and .NET 4.0 in addition to .NET Standard 1.3 and .NET Framework 4.6 ### Changed - Fixed issue where assembly version wasn't set in assembly. ## Version 2.7.1 - 2017-01-31 ### Changed - Fixed crash when validation is invoked on .NET Framework with strong-naming enforced. ## Version 2.7.0 - 2017-01-24 ### Added - SDK now supports .NET Standard 1.3 ### Changed - Moved to using System.IO.Packaging from dotnet/corefx for .NET Standard 1.3 and WindowsBase for .NET 4.5. - Cleaned up project build system to use .NET CLI. ## Version 2.6.1 - 2016-01-15 ### Added - Added hundreds of XUnit tests. There are now a total of 1333 tests. They take about 20 minutes to run, so be patient. ## Version 2.6.0 - 2015-06-29 ### Added - Incorporated a replacement `System.IO.Packaging` that fixes some serious (but exceptional) bugs found in the WindowsBase implementation
