• Call stack view – The process thread call stack that led to the event which suspended the debugged process run is displayed. Such events include: breakpoint hit, OpenGL errors, step, break and second chance exceptions.
• Source code viewer - Displays a call stack function's source code file. The line where a call to the next call stack function appears is highlighted.
• User Guide – gDEBugger User Guide (Help -> User Guide).

Changed:

• Enhanced views: gDEBugger views are now resizable. You can change their size, hide, restore, undock and dock them.
• A debug notice is displayed if OpenGL has already recorded an error when turning on "Break on OpenGL Errors" instead of reporting an OpenGL error on the current function call.
• Enhanced license mechanism - The days left until the trial version expires are displayed in the application title bar.
• The debugged process is suspended when second chance exceptions occur. This allows you to observe the thread call stack that led to the exception.
• Debug settings dialog - Added default directories.

Fixed bugs:

• When opening a workspace, the old workspace breakpoints and state variables were not saved in the workspace file.
• gDEBugger sometimes froze when the debugged process threw foreign breakpoint exceptions (breakpoints not initiated by gDEBugger).
• When the debugged application stepped into a glBegin-glEnd block using the "Step" command an OpenGL error was triggered.
• After starting and stopping the debugged application a few times (using the "Stop debugging" command), gDEBugger displayed the following message: "Communication between the debugged application and gDEBugger failed".
• gDEBugger failed to debug applications on WinXP Service Pack 1 and 2 when running gDEBugger.exe from a command line.

• gDEBugger now supports applications that load OpenGL32.dll dynamically after the process run starts.
• Display monitor information was added into the system information dialog (Tools -> System information -> Display tab)
• An error message is displayed when gDEBugger fails to communicate with the debugged application.

Changed:

• The function that caused the breakpoint hit / OpenGL error is now displayed with a marking yellow arrow (->) in the ("OpenGL functions call history" view).
• The "Breakpoints" dialog functions list is now sorted alphabetically. The user can type the function prefix and the list will scroll to the right location.

Fixed bugs:

• The first command line argument was not passed to the debugged application.
• Breakpoint and step events displayed wrong properties when the event was not the last reported event (Properties view).
• Break event was displayed as step event (Debugged Process Events view).

• Support OpenGL 1.4 and 1.5 versions.
• Support Windows XP Service pack 2.
• The following extension support:
     - GL_ARB_occlusion_query
     - GL_ARB_texture_cube_map
     - GL_ARB_texture_compression
     - GL_HP_occlusion_test
     - GL_NV_primitive_restart
     - GL_NV_occlusion_query
     - WGL_I3D_genlock

Changed:

• Pause stops the application run at the next OpenGL function call (and not immediately).

Fixed bugs:

• Pause sometimes made the debugged application stuck.
• State variable values were not displayed after executing pause (OpenGL state variables view).
• Not all the loaded / unloaded DLL names were displayed (Debugged process events view).
• A false "wglGetPixelFormat" call appeared after each extension function call (OpenGL function calls history view).

• Support OpenGL 1.2 and 1.3 versions.
• "Break on OpenGL error" option.
• The displayed OpenGL state variables are saved into the breakpoints project file.

Changed:

• Application GUI enhancements - WinXP look and feel, enhanced views frames.
• String arguments values are displayed instead of the string pointer value (Example: wglGetProcAddress argument).
• Breakpoints menu was added (breakpoint menu items previously resided in the Debug menu).
• The machine path is now divided into directories (Tools -> System information ->System tab).
• The log file name now contains the debugged application name.
• Removed the right click customization menu (It was replaced by the View menu).
• Removed the views grab handles, X and > (free the space they consumed).
• Removed the row drag handles (free the space they consumed).

Fixed bugs:

• Crash when loading twice the "new workspace" wizard.
• State variables values sometimes got garbage values instead of "N/A"
• Dates and times smaller that 10 are now padded with 0's. Example: 3:9:55 -> 03:09:55
• The GL_LINES and GL_POINTS enumerations were displayed incorrectly.

• Save the OpenGL calls log into a file (OpenGL functions call history toolbar -> Record button).
• System information dialog now supports OpenGL and WGL extensions information (Tools ->System Information -> OpenGL Extensions Tab)
• Ignore all breakpoint was added into the debug menu and allocated with a shortcut key (Ctrl-I)
• Context ID is written into the saved OpenGL state variables file.

Changed:

• Shortcut keys of the debug commands were changed.

Fixed bugs:

• Some applications throw an "access violation" exception and exit on application launch from gDEBugger.
• In some cases, gDEBugger didn't run from a command line shell.
• When loading a gdb file – the title of the application didn't specify the debugged application name.
• Indentation problems when outputting strings into a file.
• When creating new workspace the old workspace was not saved.
• The working directory was not change automatically when typing manually the debugged application exe path in the new project wizard.

• Save OpenGL state variables snapshot to a file (File -> Save state variables)
• Display the values of vector and matrix arguments instead of just the vector/matrix pointer (OpenGL calls history view).
• When an OpenGL functions input a GLenum through a GLfloat argument - display the enum value.
• Check for updated gDEBugger version (Help -> Check for updates).
• Send feedback option (Help -> Send us feedback).
• Computer Graphic Card renderer information (Tools ->System Information -> Graphic Card Tab)

Changed:

• Improved license expired message box.
• Improved Help about dialog.
• Changed toolbars and views names.
• Changed the look of the installation dialogs.

Fixed bugs:

• When using X to close the "select workspace" dialog, the debug settings was corrupted.
• Save workspace sometimes saved wrong workspace information.
• Do not highlight a state variable as changed when switching from N/A to a real value (OpenGL state variables view).

• State variable view.

Fixed bugs:

• gDEBugger gets stuck when the debugged .exe file does not exist.
• In some scenarios, when pressing the X button, gDEBugger exits with errors.
• Viewing a calls log that contains enum values may produce errors.
• Step does not work well when used on process startup.
• View and Toolbars are not synchronized with the view menu.
• When the process is suspended, the views are updated twice.
• Views size was not adjusted correctly when using different screen resolutions.
