+-----------------
+
+JH/01 Bug 1329: Fix format of Maildir-format filenames to match other mail-
+      related applications.  Previously an "H" was used where available info
+      says that "M" should be, so change to match.
+
+JH/02 Bug 2587: Fix pam expansion condition.  Tainted values are commonly used
+      as arguments, so an implementation trying to copy these into a local
+      buffer was taking a taint-enforcement trap.  Fix by using dynamically
+      created buffers.
+
+JH/03 Bug 2586: Fix listcount expansion operator.  Using tainted arguments is
+      reasonable, eg. to count headers.  Fix by using dynamically created
+      buffers rather than a local.  Do similar fixes for ACL actions "dcc",
+      "log_reject_target", "malware" and "spam"; the arguments are expanded
+      so could be handling tainted values.

+JH/41 Bug 2571: Fix SPA authenticator.  Running as a server, an offset supplied
+      by the client was not checked as pointing within response data before
+      being used.  A malicious client could thus cause an out-of-bounds read and
+      possibly gain authentication.  Fix by adding the check.
+
+JH/42 Internationalisation: change the default for downconversion in the smtp
+      transport to be "if needed".  Previously it was "as previously set" for
+      the message, which usually meant "if needed" for message-submission but
+      "no" for everything else.  However, MTAs have been seen using SMTPUTF8
+      even when the envelope addresses did not need it, resulting in forwarding
+      failures to non-supporting MTAs.  A downconvert in such cases will be
+      a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
+      transport.  The change does mean that addresses needing conversion will
+      be converted when previously a delivery failure would occur.
+
+JH/43 Fix possible long line in DSN.  Previously when a very long SMTP error
+      response was received it would be used unchecked in a fail-DSN, violating
+      standards on line-length limits.  Truncate if needed.
+
+HS/01 Remove parameters of the link to www.open-spf.org. The linked form
+      doesn't work. (Additionally add a new main config option to configure the
+      spf_smtp_comment)
