The signature of FeedsProcessor::entityValidate() changed

The signature of the method FeedsProcessor::entityValidate() changed. It now has a second optional parameter.

If you extend the FeedsProcessor class and override the method entityValidate() you'll need update the signature: add , FeedsSource $source = NULL in the method's parameters section.
Otherwise you would get a PHP warning like the following:

Declaration of MyProcessor::entityValidate() should be compatible with FeedsProcessor::entityValidate($entity, FeedsSource $source = NULL)

If you were calling parent::entityValidate($entity); in your code, be sure to update that to parent::entityValidate($entity, $source);.

Before

protected function entityValidate($entity) {
  parent::entityValidate($entity);

After

protected function entityValidate($entity, FeedsSource $source = NULL) {
  parent::entityValidate($entity, $source);
