Fixed #37152 -- Raised ValueError when Bcc is used in EmailMessage headers.

2026-06-16T22:56:20Z

Bcc addresses are sent via the SMTP envelope and must never appear in the message itself. A "Bcc" key in `extra_headers` was not excluded like From/To/Cc/Reply-To, so it leaked into the generated message as a visible header. Thanks Mike Edmunds for reviews.

Refs #36532 -- Optimized CSP decorator async checking.

2026-06-16T20:54:39Z

The previous approach created both sync and async wrappers before checking which one was needed. Checking first reduces about 1 microsecond off each decorator application.

Fixed #37163 -- Optimized @user_passes_test async checking.

2026-06-16T15:48:22Z

Fixed #31317 -- Avoided crash in CreateModel with unique_together and AlterUniqueTogether.

2026-06-11T20:26:32Z

Thanks Johannes Maron for reviews.

Fixed #37141 -- Added --using option to sendtestemail command.

2026-06-11T17:53:46Z

2026-06-11T15:02:36Z
