The What's New notes of versions 7.0 to 11.0 list no member of TX Spell .NET for Windows Forms that was changed or removed, and none is marked obsolete. An upgrade therefore changes your project, not your code, plus a few behaviors worth testing. When your application uses TX Text Control as well, read its breaking changes too, as [Update Together With TX Text Control](https://docs.textcontrol.com/tx-spell-dotnet-winforms/whats-new/breaking-changes/#update-together-with-tx-text-control) describes.

### By the Version You Come From

An upgrade from 10.0 needs a project that targets .NET 8 or higher; an upgrade from a version earlier than 7.0 needs the .NET Framework 4.0 or higher. Beyond the target framework, test the suggestions (changed in 10.0), user dictionaries with flags and the scaling of the dialog boxes (both changed in 8.0). [Breaking Changes](https://docs.textcontrol.com/tx-spell-dotnet-winforms/whats-new/breaking-changes/llms-full.txt) in What's New describes each change in full, with a table of what to change and what to test for the version you come from, and [Deprecated APIs](https://docs.textcontrol.com/tx-spell-dotnet-winforms/whats-new/deprecated-apis/llms-full.txt) confirms that nothing is marked for removal.
