linkchecker 7.x-1.0

This release contains a major new feature that took nearly 4 years to get accomplished. With the HTTPRL module the Link checker module is able to check your urls in parallel. Compared to Drupal core with typically 80-120 url checks per cron run, the tests with HTTPRL have shown that 800-1400 links per cron run are typical with 8 simultaneous connections. More simultaneous connections are not recommended! Many thanks to mikeytown2 for his help on the integration.

Drupal 7.15 or later
