- QDesktopWidget on X11 no longer emits the resized(int) signal when screens
are added or removed. This was not done on other platforms. Use the
screenCountChanged signal instead
-
+
- QUrl's parser is more strict when for hostnames in URLs. QUrl now
enforces STD 3 rules:
-
+
* each individual hostname section (between dots) must be at most
63 ASCII characters in length;
-
+
* only letters, digits, and the hyphen character are allowed in the
ASCII range; letters outside the ASCII range follow the normal
IDN rules
-
+
That means QUrl no longer accepts some URLs that were invalid
before, but weren't interpreted as such.
-
+
- The Unix configure-time check for STL is stricter now in Qt
4.6.0. This means some legacy STL implementations may fail to pass
the test and, therefore, Qt will automatically disable STL support.
-
+
This is a binary-compatible change: existing code will continue to
work without being recompiled. However, it affects the source code,
since some STL-compatibility API will not be enabled.

Platforms affected by this change:
* solaris-cc-* with the default (Cstd) C++ STL library
recommendation: use -library=stlport4
See Sun Studio's documentation for the effects of this option
+
+ - QVariant has now a new implicit constructor that takes a float. This
+ means that code that assigned a float to a variant would create a
+ variant with userType QMetaType::Float, instead of QVariant::Double.
