Changes for version 0.12 - 2026-10-04
- undo() rebuilt a base64 or quoted-printable body encoded twice: Recipes work on wire lines, so the rebuilt body is already in its transfer encoding, and Email::MIME->body_set encoded it again. Every such message a list re-encoded (footer appended, body re-wrapped) failed "m=1 does not match content" and the milter refused to sign it -- 17 of 88 charset-corpus samples through Mailman, while the Python undo rebuilt them byte for byte. The body is now set as raw octets. (t/undo-encoded-body.t)
- DKIM2_DATE is 2026-10-04: the Message-Instance headers this library emits changed shape in 0.11 ("b" literals, integer copy ranges), and the X-DKIM2-Info date stamp follows emitted-header changes.
