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.

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
