6.1.34

Two months ago, we launched our most monumental release yet: Uno Platform 6.0. It introduced a unified Skia rendering engine for Uno Platform across all target platforms and officially declared our premium tooling, Uno Platform Studio, as generally available. Together, they streamline your .NET development, allowing you to build cross-platform .NET apps in record time.

Two months may seem like a long time (and yes, we took a bit of a breather after our 6.0 release), but even during that time, our team and community still managed to finalize over 300 pull requests, refining previous releases and adding new features.

Full Changelog: 5.6.33...5.6.61

5.6.30

In Uno Platform 5.6, our first release of 2025, we’re doubling down on what matters most to you — productivity, performance, and seamless cross-platform development experiences. There are major advancements across the board, from faster Hot Reload and expanded app packaging support to significant runtime and memory optimizations.

• Hot Reload continues to evolve and lead the .NET ecosystem. As it is the foundation of Hot Design, our next-generation visual designer, nothing short of an amazing Hot Reload experience will satisfy us.
• App packaging is now even easier, with new support for .pkg and .dmg formats, code signing, notarization, and destructive mode Snap package creation for CI environments.
• Performance improvements across Uno Platform include up to 10x faster execution for Wasm AOT, more efficient visual states, and memory optimizations that make apps leaner and faster.

Take a look at our blog post for now details!
