OR, HAVING, GROUP BY clauses,
- No more "Views OR"
- We have aggregation a.k.a Group by

7. V2 vs V3:Differences:backend:functionals
Pager, exposed & i18n
- System more pluggable
- Now we can change and specific funtionality, we are working with classes and inheritance (i.e
exposed filters)
- We'll see how to!!
Multiple footer and headers
- Depends of the context
- <IMHO>I think it's too limited, </IMHO>

8. V2 vs V3:Differences:backend:code
- System more pluggable
- More comments
- Add new compatibilities (many settings differences between V2 and v3
- Introduce Group by
- A lot of commented functions
- Hooks
● V2 #hooks = 23 || V3 #hooks = 21
● New hooks in V3
○ hook_views_ajax_data_alter: This hook allows to alter the commands which are used on a views
ajax request.
○ hook_views_invalidate_cache: Allow modules to respond to the Views cache being invalidated.
○ hook_views_ui_display_top_links_alter: This hooks allows to alter the links at the top of the view
edit form. Some modules might want to add links there.
● Removed hooks in V3
○ hook_views_convert
○ hook_views_handlers: How should we do it?
○ hook_views_form_submit
○ hook_views_form_validate
○ hook_views_admin_links_alter
