Key enhancements in these releases include:
- New assertions, for instance ones that operate on JSON data
- Redesigned code coverage report
- It is possible again to expect (with @expectedException) the generic Exception class. Doing so is still a bad idea, though.
Please note that PHPUnit 3.7 is only supported on PHP 5.3.3 (or later) and that PHP 5.4.7 (or later) is highly recommended. While PHP_CodeCoverage still works with Xdebug 2.0.5, upgrading to Xdebug 2.2.1 (or later) is highly recommended.
The full list of changes are listed in the ChangeLog of each project (linked above).
