Version	Description
7.2.0	Usage of a string as the assertion became deprecated. It now emits an E_DEPRECATED notice when both assert.active and zend.assertions are set to 1.
7.0.0	assert() is now a language construct and not a function. assertion can now be an expression. The second parameter is now interpreted either as an exception (if a Throwable object is given), or as the description supported from PHP 5.4.8 onwards.
5.4.8	The description parameter was added. The description is also now provided to a callback function in ASSERT_CALLBACK mode as the fourth argument.
