Welcome to the CDT Release update site. All releases compatible with Eclipse 2.x are available here.
To install a release, from the Update Manager, create a Site Bookmark that points to the following URL:
http://update.eclipse.org/tools/cdt/updates/release
Open the bookmark and select the desired features to install. As of
release 1.2, you must install one or both of the builder features for
the CDT to function.
For those writing extensions to the CDT, or just would like to take
a look at the code, the Source feature can be installed to enable
automatic source attachment for importing the CDT plugins as binary
plugins.
