Release

This is the New & Noteworthy page for CDT 9.4 which will be part of Eclipse Oxygen.2

Editor

Open Declaration on `decltype`	Open Declaration on a `decltype` token now opens the declaration of the deduced expression type (bug 520913).

A new quick fix was added for suppressing a problem by adding a suppression comment (bug 495842).

Headless Build

Headless build has three new command line arguments:

-marker-type which specifies which marker types to consider when failing a build. Can be all (default) cdt (shortcut for C/C++ Problems) or any marker ID. Can be specified multiple times to check for multiple markers. Can be used to, for example, prevent C/C++ Scanner errors from causing build failures.
-printErrorMarkers prints all error markers (debugging option) at the end of a build. Can be used to diagnose why build has failed (specific error markers).
-help display help.

org.eclipse.cdt.debug.gdbjtag.ui	The method GDBJtagStartupTab#createRunOptionGroup(Composite) has been deprecated because the the content of the run options group and the run commands group has been merged within the Startup page of the UI (see bug 525692). Extenders should use override GDBJtagStartupTab#createRunGroup(Composite) instead.
