+Box2D.NET Release 🎉
+
+We’re excited to announce the first release of Box2D.NET 3.1.0!
+This is a C# port of the original Box2D, which was written in C — now bringing a lightweight and fast 2D physics engine to the .NET ecosystem.
+
+More than just a direct port, it’s been carefully refined to feel natural and intuitive for C# developers.
+After many trials and iterations, we’re truly happy to finally share the result.
+
+Huge thanks to everyone who showed interest and supported the project along the way! 🙏
+
+### Special Thanks
