========


- Neue Kolonnen "Aktive Akten" und "Komplette Akten" in der 
  Übersichtstabelle :func:`Klienten pro Benutzer 
  <lino.apps.dsbe.models.persons_by_user>`.


- The parameters :attr:`lino.core.table.Table.filter` and 
  :attr:`lino.core.table.Table.exclude` are no longer expected to be 
  `dict` objects, but `models.Q` objects.
  
- New field `PersonGroup.active` used in 
  :func:`lino.apps.dsbe.models.persons_by_user`.
  
- Decimal fields were not handled correctly. 
  It was not possible to enter decimal (non-integer) values even 
  if `decimal_places` was set to 2.
  New Lino configuration attribute :attr:`lino.Lino.decimal_separator`.
  
Check-in wegen Feierabend.
