-> [v3.0.0 beta 1](https://www.nuget.org/packages/DocumentFormat.OpenXml/3.0.0-ci0083) refactors and addresses some technical debt, with the goal to retain (as much as possible) source compatibility. We hope to maintain things such that you can update your package and recompile with limited changes. However, binary compatibility is not a goal and will break that for some changes which we plan on keeping documented. PRs that introduce such changes are marked with a `breaking-change` label and are added to a list to help migrating to v3.0.0.

-The functionality of the specific classes in this version of the Open XML SDK is similar to version 2.5, therefore the [Open XML SDK 2.5 for Office](http://msdn.microsoft.com/en-us/library/office/bb448854.aspx) documentation available on MSDN is still accurate.

 In addition to open sourcing of the SDK, Microsoft has opened up the conceptual documentation for public review / contributions.  A copy of the documentation is  available for you to edit and review [in GitHub](https://github.com/OfficeDev/office-content).
