Prevent notices when an anonymous user tries to run an action with insufficient permissions (which usually happens on cron).

Removed the VBO_AGGREGATE_FORCED / VBO_AGGREGATE_FORBIDDEN / VBO_AGGREGATE_OPTIONAL constants. The 'aggregate' flag is now a boolean.

Fix the Cancel button not appearing on the config step. Use ->get_url() instead of ['q'] for redirecting back to the View.

One of the 'tweaks' was wrong. Fix that so that the correct plural form is always used in the confirmation screen, even if we don't show the number of rows selected (as suggested in #1198222)

Port the VBO configuration form changes from 6.x-1.x, allowing custom labels and confirmation skipping per action.

Enable the delete action by default on the default VBO views. Fix a bug causing the message after an action to always say that 1 row was modified.

Issue #724686 by dafeder, bojanz - Add a 'force single' option, making VBO show radios instead of checkboxes

Core actions integration: Add back support for the 'behavior' key, save explicitly all entities that need to be saved (as specified through behavior).

Pass the full entities when aggregating results for an action, not just the ids (since everything is already loaded anyway). Tweak the 'pass ids to url' and 'execute script' actions a bit.

Move VBO's validate / submit logic to custom callbacks, implementing hook_views_form_validate / hook_views_form_submit will get expensive once more modules start implementing views forms.

Since views_form has been merged into views, remove the views_form dependency and make VBO compatible with the newest changes.

Performance optimizations. Brought back the '... and X more' text to the confirmation screen, stopped storing entire rows in the session, became more careful with entity_load, massively improved the speed of selecting all items (the 'adjust' function).
