Crawler::each() andCrawler::reduce() now return Crawler instances instead of DomElement instances:

Before:

$data = $crawler->each(function ($node, $i) {   return $node->nodeValue;});

After:

$data = $crawler->each(function ($crawler, $i) {   return $crawler->text();});

These changes should get documented in thecomponents/dom_crawler article in the following examples:
