views_send 8.x-1.1

This maintenance release fixes

• #2863488: Fatal error when dblog module is disabled
• #2879094: Hidden fields of the view are available in the field selection of the sending form
• #2842725: Call to undefined function rules_invoke_event() in views_send.module
• #2843871: Remove @file tag docblock from all the .php files.
• #2843872: Use $this->t() instead of t() in classes

In addition the Views Send field configuration has been simplified by removing irrelevant settings. (This is not the much requested simplification of configuring the actual mail to be sent.)

I have also tested that Views Send still works for Drupal 8.4.

NB! Enabling the Rules module doesn't break the module anymore. However, the Rules integration isn't complete yet since it is unclear to me how to create the needed data type.
