Description: 

element_validate_integer() and element_validate_integer_positive() have been removed.

Before:

$form['count'] = array(
  '#type' => 'textfield',
  '#title' => t('Item count'),
  '#description' => t('Enter a number of items'),
  '#element_validate' => array('element_validate_integer_positive'),
);

After:

$form['count'] = array(
  '#type' => 'number', // New HTML 5 number type.
  '#title' => t('Item count'),
  '#description' => t('Enter a number of items'),
  '#min' => 0, // Use this to replace element_validate_integer_positive() validation.
               // Having just #type => 'number'
               // already replaces element_validate_integer().
);

See the number element change notification for more information about the new number element type.
