Qt 5.15.1 is a bug-fix release. It maintains both forward and backward
|

The Qt version 5.15 series is binary compatible with the 5.14.x series.
|
||||
Applications compiled for 5.14 will continue to run with 5.15.

|
||||
accessed on ApplicationWindow or another non-Item object.
|

|
||||
* [QTBUG-40220] If polish() is called within updatePolish(), or a polish

loop occurs for some other reason, the detection is now more correct, and

||||
changes are not immediately emitted after a layout has been modified.
|
||||
|
||||
- MouseArea:
|
||||

||||
QQuickWidget now becomes visible even though the parent window is offscreen.
