This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.
It DOES NOT substitute the  CVS log-message one should put at every

-----------------------------------------------
12 November 2021 - Ben Morgan (visQt3D-V10-07-12)
- Retire G4VIS_... preprocessor symbols in toolkit build, only required
  by obsolete GNUmake system

8 November 2021 - Ben Morgan (visQt3D-V10-07-11)
- Retire G4UI/G4INTY_... preprocessor symbols in toolkit build, only required
  by obsolete GNUmake system

20 October 2021  Gabriele Cosmo  (visQt3D-V10-07-10)
- Fixed broken dependency in GNUmakefile...

18 October 2021  John Allison  (visQt3D-V10-07-09)
- G4Qt3DSceneHandler:
  - Introduce AddCompound(const G4Mesh&).
    - This copies G4OpenGLSceneHandler.
    - Subsequently it may be refined for Qt3D - but works well for now.

01 September 2021  John Allison  (visQt3D-V10-07-08)
- G4Qt3DSceneHandler.cc:
  o Raise G4Exception if no available node.
- G4Qt3DViewer.cc:
  o Protect against illegal call to show() - it may only be called from
    the master thread.

22 August 2021  John Allison  (visQt3D-V10-07-07)
- Fix the problem of drawing from the vis sub-thread.

20 August 2021  John Allison  (visQt3D-V10-07-06)
- Minor updates - optional debug printing, etc.
- Revert to black background.
- Add G4Qt3DViewer::MovingToVisSubThread and MovingToMasterThread.

07 June 2021  John Allison  (visQt3D-V10-07-05)
- Requires greps-V10-07-07 (new method AddCompound (const G4Mesh&)).
- Requires modeling-V10-07-09 (new class G4Mesh).
- Requires visman-V10-07-10 (new default method and new commands).
- G4Qt3DViewer.hh:
  o Fix hidden function warning.
- G4Qt3DViewer.cc:
  o Force kernel visit if special mesh rendering parameters change.

28-May-2021 Ben Morgan (visQt3D-V10-07-04)
- Migrate to modular CMake build

27 May 2021  John Allison (visQt3D-V10-07-03)
- AddPrimitive(const G4Polyhedron&):
  o Minor improvement to error message in the case of unexpected number
    of edges.

17-Apr-2021  John Allison  (visQt3D-V10-07-02)
- Fix compiler warning (unused variable "text")

08-Apr-2021  John Allison  (visQt3D-V10-07-01)
- Move //#define G4QT3DDEBUG to G4Qt3DUtils.hh.
  o Improve overall protection of debug output with #ifdef G4QT3DDEBUG.
- Include some trial code for text output, but comment it out.

29-Dec-2020  John Allison  (visQt3D-V10-07-00)
- G4Qt3DViewer: Move code from constructor to G4Qt3DViewer::Initialise().
- G4Qt3DSceneHandler:
  o Implement auxiliary edge suppression.
  o Tidy up G4Qt3DSceneHandler::AddPrimitive(const G4Text& - still doesn't work.

29-Oct-2020  Ben Morgan (visQt3D-V10-06-02)
- Remove inclusion of obsolete CMake module

26-Oct-2020  Gabriele Cosmo  (visQt3D-V10-06-01)
- Corrected GNUmake setup and fixed compilation warnings.

23-Oct-2020  John Allison  (visQt3D-V10-06-00)
- First version.
- Requires cmake-V10-06-34.

27-Sep-2019  John Allison
- First skeleton. Based on XXXSG driver.
