Features

  • Add support for Python 3.12.

  • Added HTTP 418 error code via pyramid.httpexceptions.HTTPImATeapot. See #3667

  • Coverage reports in tests based on Python 3.12 instead of Python 3.8.

  • All scripts now pass a new option __script__ when loading the WSGI app. For example, pserve sets __script__ == 'pserve'. This works for pserve, pshell, prequest, proutes, ptweens, pviews, as well as when using pyramid.paster.bootstrap directly.

    When using plaster-pastedeploy to load an INI file, this option will manifest as a new value passed into the global_conf arg of your application factory, where you can use it as part of initializing your app.

    See #3735

  • Replace usage of md5 in the Pyramid view system with sha256. This is not a security-related feature and is considered an implementation detail that should not impact users.

    See #3745

  • Replace usage of pkg_resources in pyramid.path.DottedNameResolver. See #3748

  • Replace usage of pkg_resources in pdistreport and pshell CLI commands. See #3749

Bug Fixes

  • Fix issues where permissions may be checked on exception views. This is not supposed to happen in normal circumstances.

    This also prevents issues where a request.url fails to be decoded when logging info when pyramid.debug_authorization is enabled.

    See https://github.com/Pylons/pyramid/pull/3741/files

  • Applications raising pyramid.exceptions.BadCSRFToken and pyramid.exceptions.BadCSRFOrigin were returning invalid HTTP status lines with values like 400 Bad CSRF Origin instead of 400 Bad Request.

    See #3742

Backward Incompatibilities

  • Drop support for Python 3.6 and 3.7.
  • Drop support for l*gettext() methods in the i18n module. These have been deprecated in Python's gettext module since 3.8, and removed in Python 3.11.

Deprecations

  • Deprecated the ability to use a non-existent package with pyramid.config.Configurator.add_static_view and pyramid.static.static_view. This can be fixed by choosing a path located within a real package as the root_dir for your static files. This is almost always either a misconfig or an attempt to define an alias location for use with pyramid.config.Configurator.override_asset. See #3752

Documentation Changes

  • Sync the SQLAlchemy Wiki tutorial with changes to the pyramid-cookiecutter-starter. Includes updates to use pyproject.toml to replace separate config files for pytest, coverage, and setuptools. Also upgrades patterns to support SQLAlchemy 2.0. See #3747
  • Sync the ZODB Wiki tutorial with changes to the pyramid-cookiecutter-starter. Includes updates to use pyproject.toml to replace separate config files for pytest, coverage, and setuptools. See #3751
