The container classes are implicitly shared, they are reentrant, and they are optimized for speed, low memory consumption, and minimal inline code expansion, resulting in smaller executables. In addition, they are thread-safe in situations where they are used as read-only containers by all threads...
The ISO C++ Standard specifies that all virtual methods of a class that are not pure-virtual must be defined, but does not require any diagnostic for violations of this rule [class.virtual]/8. Based on this assumption, GCC will only emit the implicitly defined constructors, the assignment op...

Values for enums declared with Q_ENUMS are not available as properties of individual wrapper objects; rather, they are properties of theQMetaObjectwrapper object that can be created withQScriptEngine::newQMetaObject(). Conversion Between QtScript and C++ Types ...

Single argument value object constructors are now marked as explicit. For example,SpatialReference(int wkid)is now explicit, which means passing an int into a function that requires aSpatialReferenceobject will no longer implicitly convert. Signal arguments have been standardized to beconst-refthroughou...
