Some major changes have happened:
- Automatic test discovery has been added. It's no longer required to manually define tests.
- Multiple tests per unit are now supported.
And there are other minor but important changes too:
- Added a tweakable way to rebuild the whole project automatically if the GNUmakefile changes.
- Temporary files (test objects, binaries and timestamps) are now built to a hidden unified directory named
.caddeus. - NDEBUG is no longer defined on release trees.
- Unused function parameters are treated as warnings by default now.
- Overall code quality has been improved.
