Release summary

This release continues working on the Model Context Protocol (MCP) server introduced in 1.2.0-alpha01, adding three new tools, multi-window support, multi-root handling for semantic tree and reload-state reporting in status. It also improves the error-reporting experience in the Dev Tools notification overlay and raises minimal supported Compose version to 1.10.0.

Am I doing something wrong or why isn't the copy icon/button not showing up?

[Niklas Baudy (vanniktech)]

Oh yes, I need to make the window way way way bigger:

Can this be fixed, such that the icons are always shown? I already do love the button though, it does exactly what I want ❤️

[Azat Abdullin (AbdullinAM)]

Yes, I will fix this. I attached the buttons to the wrong line
