Fixed #35514 -- Implemented dictionary-based MAILERS.

2026-05-13T21:00:56Z

See DEP 0018. Added: * MAILERS setting. * django.core.mail.mailers dict-like EmailBackend factory. * `using` argument to mail sending APIs. * `sent_using` attribute to mail.outbox messages in locmem backend. * MAILERS in startproject settings template, set to console backend. * AdminLogHandler.using argument. * BrokenLinkEmailsMiddleware.send_mail() method. Updated: * BaseEmailBackend to track the MAILERS alias used to construct it, and to report errors for unknown kwargs (OPTIONS). * EmailBackend implementations to initialize from kwargs (OPTIONS) only when MAILERS is being used. * smtp.EmailBackend to require `host` option and to default `port` option based on SSL/TLS options. * SimpleTestCase setup to substitute the locmem backend for all defined MAILERS configurations. * Django's tests that send mail to define MAILERS. Deprecated: * EMAIL_BACKEND and other backend-related EMAIL_* settings. * mail.get_connection(). * The `connection`, `fail_silently`, `auth_user`, and `auth_password` arguments to mail functions. * The EmailMessage.connection attribute. * BaseEmailBackend support for `fail_silently`. Backends that support fail_silently (SMTP, console, file) now implement it directly. * AdminEmailHandler.email_backend argument. Removed undocumented features without deprecation: * EmailMessage.get_connection() method. (send() now raises an error if a subclass has attempted to override it.) * EmailMessage.send() no longer sets self.connection to the connection used for sending. (It still _uses_ a pre-existing self.connection.) * AdminEmailHandler.connection() method. (Init now raises an error if a subclass has attempted to override it.) Thanks to Natalia Bidart for shepherding DEP 0018 and for extensive reviews and suggestions on the implementation. Thanks to Jacob Rief for the initial implementation and multiple iterations while refining the design. Co-authored-by: Jacob Rief

Fixed CVE-2026-3902 -- Ignored headers with underscores in ASGIRequest.

Thanks Tarek Nakkouch for the report and Jake Howard and Natalia Bidart for reviews.

Refs #36770 -- Guarded against an endless wait in LiveServerThread.terminate().

2026-03-30T19:56:52Z

terminate() shouldn't assume the main server was started. (A deadlock from mishandling of in-memory SQLite databases may have occurred.)

Fixed #36958 -- Reloaded logging config when logging settings are changed in tests.

2026-03-19T16:36:34Z

Thanks JaeHyuck Sa and Jake Howard for the reviews.

Fixed #36859 -- Made assertContains and assertNotContains idempotent for streaming responses.

2026-03-16T20:44:40Z

Fixed #36966 -- Fixed ValueError when `query_params` and `follow` are used on test client.

2026-03-13T17:46:49Z

Refs #34118 -- Removed asgiref coroutine detection shims.

2026-01-31T13:59:54Z

As Python 3.12 is now the floor, we can drop the shims and use the `inspect` module.

Applied Black's 2026 stable style.
