------------------
**New features**
- Partial collection of records when user has no ``read`` permission on collection (fixes 76).
Alice can now obtain a list of Bob records on which she has individual ``read`` permission!

The feature is marked as *experimental* and should be explicitly enabled
from settings (181)
- Accept empty payload on buckets and collections creation (63)
- Allow underscores in Kinto bucket and collection names (153, fixes 77)
- Collection records can now be filtered using multiple values (``?in_status=1,2,3``) (mozilla-services/cliquet39)
- Collection records can now be filtered excluding multiple values (``?exclude_status=1,2,3``) (mozilla-services/readinglist68)
- Current userid is now provided when requesting the hello endpoint with an ``Authorization``
header (mozilla-services/cliquet319)
- UUID validation now accepts any kind of UUID, not just v4 (mozilla-services/cliquet387)
- Querystring parameter ``_to`` on collection records was renamed to ``_before`` (*the former is now
deprecated*) (mozilla-services/cliquet391)
- Allow to configure info link in error responses with ``cliquet.error_info_link``
setting (mozilla-services/cliquet395)
**Bug fixes**

The list of principals for each specified permission is now replaced by the one
provided.
