Deprecated

• The methods assertInternalType() and assertNotInternalType() are now deprecated. There is no behavioral change in this version of PHPUnit. Using these methods will trigger a deprecation warning in PHPUnit 8 and in PHPUnit 9 these methods will be removed.

There is no behavioral change in this version of PHPUnit. Using these methods will trigger a deprecation warning in PHPUnit 8 and in PHPUnit 9 these methods will be removed.
• The optional parameters $delta, $maxDepth, $canonicalize, and $ignoreCase of assertEquals() and assertNotEquals() are now deprecated. There is no behavioral change in this version of PHPUnit. Using these parameters will trigger a deprecation warning in PHPUnit 8 and in PHPUnit 9 these parameters will be removed.
• The annotations [**expectedException**](https://github.com/expectedException), [**expectedExceptionCode**](https://github.com/expectedExceptionCode), [**expectedExceptionMessage**](https://github.com/expectedExceptionMessage), and [**expectedExceptionMessageRegExp**](https://github.com/expectedExceptionMessageRegExp) are now deprecated. There is no behavioral change in this version of PHPUnit. Using these annotations will trigger a deprecation warning in PHPUnit 8 and in PHPUnit 9 these annotations will be removed.
• Using the methods assertContains() and assertNotContains() on string haystacks is now deprecated. There is no behavioral change in this version of PHPUnit. Using these methods on string haystacks will trigger a deprecation warning in PHPUnit 8 and in PHPUnit 9 these methods cannot be used on on string haystacks anymore.
• The optional parameters $ignoreCase, $checkForObjectIdentity, and $checkForNonObjectIdentity of assertContains() and assertNotContains() are now deprecated. There is no behavioral change in this version of PHPUnit. Using these parameters will trigger a deprecation warning in PHPUnit 8 and in PHPUnit 9 these parameters will be removed.
