Pyramid 1.9a1 released

[Michael Merickel]

Hey folks, this is the first alpha release in the Pyramid 1.9 series.

This release contains some exciting new features with no known backward incompatibilities.

- Added a new execution policy hook that can be used by plugins to control the entire execution cycle of a request. The first implementation is pyramid_retry which the cookiecutters will be updated to use.

- Added support for alternative file formats other than the PasteDeploy INI format. Pyramid now uses the plaster package to lookup files based on the config_uri passed on the command-line (e.g. development.ini). To maintain backward compatibility Pyramid 1.9 depends on plaster_pastedeploy to restore integrated PasteDeploy support. This dependency may be removed in the future so applications are encouraged to depend on the specific binding they need.

- CSRF support has been decoupled from sessions and new APIs are available in the ``pyramid.csrf`` module. You can now manage CSRF tokens using a simple cookie if you wish, or any other mechanism by implementing an appropriate storage policy. By default the ``LegacySessionCSRFStoragePolicy`` is used which maintains backward compatibility for applications that are using ``request.session.get_csrf_token()``. Users should update to the new APIs to support alternate storage policies.

- The ``Configurator`` now activates threadlocals during actions and also supports being used as a context manager such that the threadlocals are active during the entire config lifecycle. The threadlocals (``pyramid.threadlocal.get_current_registry()``) are important in some situations like when depending on i18n or asset overrides at config-time.
