Upgrade to version 7.x-5.0

Hello,

The module page at https://www.drupal.org/project/webform_civicrm → says that version 7.x-5.0 is the recommended one, but gives no information on how it differs from 4.28. Neither does the release note.

I had some problems upgrading from version 7.x-4.28 to 7.x-5.0 (hoping it would deal with a couple of problems I have):

• I can't use the Drupal automatic module update because it doesn't recognise that an update exists.
• If I uninstall 4.28 and install 5.0 it loses all the connections between existing Webform fields and CiviCRM.
• In the end I just swapped the code for the new version by hand, which seems to work.

Please confirm that the latter is the recommended process.

Thank you.
