Have good unit tests on your code so you can tell what's broken after  
you update.  You can use the code-coverage features in XDebug and  
PHPUnit to see where you might be missing tests.

Recheck any assumptions written into any mock objects your tests use.   
It's up to you to verify that a mock actually behaves like the real  
thing.  When the real implementation changes, but you don't update the  
mocks, you'll have passing tests but your code is actually broken.
