4.1.0

Next release of WPF UI mainly consist of fixes provided by our wonderful community. Many people have put their hearts into working on the library.

The new version is now available on NuGet:
https://www.nuget.org/packages/WPF-UI/4.1.0

We have also added support for .NET 10 and several experimental tests with the amazing FlaUI library.

Instructions for GitHub Copilot and other agents working with MCP have also been added. I hope this will help with documentation in future releases.

Special thanks go to @Nuklon for numerous quality of life improvements, Win32 refactoring, and a number of general library performance enhancements. @chucker also added corrections and kept track of many of the changes that were made. @apachezy and @jbryknar added valuable improvements.
I would like to thank everyone else who contributed their time and enthusiasm.

Leszek aka @pomianowski

Fresh Features & Fixes!

Hey, amazing people! 👋

It’s been a while (yes, keeping tiny humans alive takes a lot of time ⏳), but we’re back with a packed release full of improvements, fixes, and even support for .NET 9! Let’s dive in.

💡 What’s New?
🔹 .NET 9 Support – Staying ahead of the game.
🔹 Package Signing – Our NuGet package is now digitally signed, ensuring package integrity.
🔹 New Abstractions Package – We’ve introduced Wpf.Ui.Abstractions to separate WPF-specific and non-WPF code, making it easier to work across different platforms.
🔹 Updated Fluent System Icons – The latest Fluent System Icons are now included, bringing new symbols and improved visuals.
🔹 Flow Improvements – Moving from main to release instead of development for a smoother workflow.
🔹 Expander Fix – Content height now behaves properly (because we love consistency).
🔹 Performance Boost – Optimized string comparison and excluded unnecessary fields for snappier performance.

…And many more!
