Announce - 0.8.6-rc2

[Alessandro Dentella]

I'm pleased to announce a new official release of sqlkit: 0.8.6-rc2.
After some more testing 0.8.6 will be the first 'stable' release.

Here are the main changes introduced.

sqlkit 0.8.6-rc2 - March, 26 2009

* sqlwidget: record_has_changed forces setting attributes in the
object: this makes validation more stable
save dialogs: much better representation of
differences that are to be saved
readonly mode now correctly sets actiongroup_edit
not sensitive

* uimanager: menus are now handled with uimanager so that was possible
to make them sensitive o context

* signals: added signal after-flush (added demo)
added delete-event to sqlwidget
'button-press-event'now has also a 'menu' arg

* filters: filters on relationships are now aliased (see note in
docs on relationship)

* hooks: hooks have been added:
+ on_completion__%s
+ on_change_value__%s
+ on_validation
+ on_field_validation__%s
+ on_activate__%s
Added 5 examples in demo

* table: added popup menu on right click on records to:
+ delete
+ view in mask (see below)
+ add new record
popup menu is changable in a simple way from
'button-press-event' signal (see demo)
better handling of silent deletion of object not changed
added View Record that can also show with a layout (see demo)

* miniwidgets: rewritten DateEdit to warn and complein of parse errors

* django2sa: now join are made in a way that is accepted by sa rel 0.5+

* utils: fixed get_differences to return all modified attributes
and added get_history

* validation: no validation on empty values (if not nullable is
triggered just before saving)

* fixes: as usual many fixes:
- back the possibility to delete foreign keys in table
- completion in m2m corner cases
- fixed hide_fields()

* fields: float now have format=None
you can now set BLANK_OK globally if instead of setting
it on all fields

* demo: many more examples and added not nullable fields and set
cascade on relation between director and movies.
