Few days after the announcement of the free version, a new version of gDEBugger is available. gDEBugger 5.8 supports the latest version of the OpenCL specification (OpenCL 1.1). Detailed changelog can be found here.

gDEBugger is an advanced OpenGL and OpenCL debugger, profiler and memory analyzer. gDEBugger does what no other tool can – lets you trace application activity on top of the OpenGL and OpenCL APIs and see what is happening within the system implementation.
gDEBugger is free and you can get a free one-year licence here.
