This is the New & Noteworthy page for CDT 9.3 which is part of the Eclipse Oxygen release of June 2017
Open Declaration now supports navigation from the definition of a class template to its forward declaration.
This can be useful in cases where some of the class template's template parameter have default arguments, as the default arguments may only be declared at the forward declaration.
Open Declaration in assembly files
The Open Declaration action is now supported in assembly files.
