Version: 3.6.4-1ubuntu1.1 2023-04-19 17:23:00 UTC

  postfix (3.6.4-1ubuntu1.1) jammy; urgency=medium

  * d/p/1995312-unexpected-eof-fix.patch: Workaround for a breaking
    change in OpenSSL 3: always turn on SSL_OP_IGNORE_UNEXPECTED_EOF,
    to avoid warning messages and missed opportunities for TLS
    session reuse. This is safe because the SMTP protocol implements
    application-level framing, and is therefore not affected
    by TLS truncation attacks. Fix by Viktor Dukhovni (LP: #1995312).
  * d/p/1996524-Linux6-support.patch: Adding LINUX6 support for
    portability (LP: #1996524).
