Release notes are at:

The 2.7.0 is a new features release. It is largely compatible with 2.6.*, but
there are some small differences which may require manual intervention
during upgrade, such as adding four new fields to an SQL schema, or
a change in a default log template which may affect log parsers.
Please review the COMPATIBILITY section of release notes for details.


- significant improvements affecting a pre-queue content filtering setup
  (time limiting, warm/flying restart, ...) - requires Postfix 2.7.0 and
  SpamAssassin 3.3.0, or later;

- new daemon amavisd-signer makes it possible to sign mail with DKIM
  signatures without requiring amavisd process to have access to private
  signing keys;

- added support for the Sophos-SSSP, Avira SAVAPI and ClamAV clamd streaming
  protocols allows amavisd to communicate with these antivirus solutions;

- allow specifying multiple (fail-over) back-end mailers for resubmission
  of messages from amavisd back to MTA;

- support for Postfix 2.8.0 XFORWARD IDENT, passes a local message identifier
  (queue id) downstream to a post-queue content filter and back to Postfix;

- speedup in data transfer rate on receiving large mail via SMTP/LMTP
  sessions by a factor of 3.9 for plain text sessions, and by a factor
  of 11 for encrypted (TLS) sessions;

- recognize and insert header fields as prepared by SpamAssassin 3.3.0
  or later through its 'add_header' configuration option;

- a new setting allows a forward_method to be chosen based on a message
  content type and/or recipient address; this may be useful for outgoing
  mail routing purposes or to implement sender reputation schemes;

- per-recipient (or per- policy bank) SpamAssassin configuration files or
  SQL configuration sets are supported (@sa_userconf_maps), and per-recipient
  SQL Bayes database usernames (@sa_username_maps);

- new macros: client_helo, client_addr, client_port, client_addr_port,
  mime2utf8, rusage, ADDEDHEADERHAM, ADDEDHEADERSPAM, banned_parts_as_attr,
  actions_performed, new arguments to macros dkim, header_field, HEADER,

- @listen_sockets setting offers a unified configuration of listening
  sockets; it may be configured directly, or the traditional way: the
  $inet_socket_port, $unix_socketname and $inet_socket_bind just add their
  entries to the @listen_sockets list;

- lists of lookup tables (the @*_maps variables) can now contain
  explicit SQL and LDAP lookup objects as their elements, instead of
  (or in addition to) the implied SQL and LDAP lookups;

- a new configuration variable @virus_name_to_policy_bank_maps allows
  loading of policy banks based on a virus name;

- a new configuration variable $mail_id_size_bits allows setting the size
  of randomly generated mail_id and secret_id codes;

- a new configuration variable $sql_store_info_for_all_msgs allows storing
  information on mail messages selectively just for quarantined messages;

- added SNMP counters InMsgsStatus* which combine the final mail checking
  status with a direction of a mail flow;

- optional transparent archival quarantine, retaining envelope recipient
  addresses on delivery to a dedicated SMTP server;
