Next release
============
Bug Fixes
---------
- Forward port from 1.3 branch: When no authentication policy was configured,
a call to ``pyramid.security.effective_principals`` would unconditionally
return the empty list. This was incorrect, it should have unconditionally
returned ``[Everyone]``, and now does.
- Explicit url dispatch regexes can now contain colons.
https://github.com/Pylons/pyramid/issues/629
- On at least one 64-bit Ubuntu system under Python 3.2, using the
``view_config`` decorator caused a ``RuntimeError: dictionary changed size
during iteration`` exception. It no longer does. See
https://github.com/Pylons/pyramid/issues/635 for more information.
- In Mako Templates lookup, check if the uri is already adjusted and bring
it back to an asset spec. Normally occurs with inherited templates or
included components.

Features
--------
- Third-party custom view and route predicates can now be added for use by
view authors via ``pyramid.config.Configurator.add_view_predicate`` and
``pyramid.config.Configurator.add_route_predicate``. So, for example,
doing this::
config.add_view_predicate('abc', my.package.ABCPredicate)
Might allow a view author to do this in an application that configured that
predicate::
@view_config(abc=1)
See "Adding A Third Party View or Route Predicate" in the Hooks chapter for
more information.
- Custom objects can be made easily JSON-serializable in Pyramid by defining
a ``__json__`` method on the object's class. This method should return
values natively serializable by ``json.dumps`` (such as ints, lists,
dictionaries, strings, and so forth).
- The JSON renderer now allows for the definition of custom type adapters to
convert unknown objects to JSON serializations.
- As of this release, the ``request_method`` predicate, when used, will also
imply that ``HEAD`` is implied when you use ``GET``. For example, using
``@view_config(request_method='GET')`` is equivalent to using
``@view_config(request_method=('GET', 'HEAD'))``. Using
``@view_config(request_method=('GET', 'POST')`` is equivalent to using
``@view_config(request_method=('GET', 'HEAD', 'POST')``. This is because
HEAD is a variant of GET that omits the body, and WebOb has special support
to return an empty body when a HEAD is used.
- ``config.set_request_property`` now causes less code to be executed at
request construction time.
- Don't add a ``?`` to URLs generated by request.resource_url if the
``query`` argument is provided but empty.
- Don't add a ``?`` to URLs generated by request.route_url if the
``_query`` argument is provided but empty.
- The static view machinery now raises (rather than returns) ``HTTPNotFound``
and ``HTTPMovedPermanently`` exceptions, so these can be caught by the
NotFound view (and other exception views).
- The mako renderer now accepts a def name and returns the template def
result for the view being called. The uri format using an asset spec is
package:path/to/template#defname.mako. The old way of returning a tuple
from the view is supported for backward compatibility, ('defname', {}).
- When there is a predicate mismatch exception (seen when no view matches for
a given request due to predicates not working), the exception now contains
a textual description of the predicate which didn't match.
