Qt 6.12 LTS Released With QML Hot Reloading and Experimental StyleKit

The Qt developers have released Qt 6.12, the newest version of the cross-platform Qt6 toolkit. What sets this release apart is its Long Term Support (LTS) status, meaning it will receive updates over an extended period — the kind of release typically chosen for products where stability and predictable maintenance matter.

Among the notable additions is QML Hot Reloading. This feature lets developers see changes to a QML-based interface without a full rebuild and restart of the application, noticeably speeding up the development cycle.

Another new arrival is StyleKit, offered for now in experimental form. Its experimental status means the component is available to try out and test, but its behavior and interface may still change in future releases.

Qt 6.12 continues the Qt6 line and, as a long-term support release, is likely to become a reference point for anyone planning to move to a current version of the toolkit.
