+Exim version 4.95
+-----------------
+
+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.  Similar fix for radius expansion condition.
+
+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/04 Bug 2590: Fix -bi (newaliases).  A previous code rearrangement had
+      broken the (no-op) support for this sendmail command.  Restore it
+      to doing nothing, silently, and returning good status.
+
+JH/05 Bug 2593: Fix "vacation" in Exim filter.  Previously, when a "once"
+      record path was given (or the default used) without a leading directory
+      path, an error occurred on trying to open it.  Use the transport's working
+      directory.
+
+JH/06 Bug 2594: Change the name used for certificate name checks in the smtp
+      transport.  Previously it was the name on the DNS A-record; use instead
+      the head of the CNAME chain leading there (if there is one).  This seems
+      to align better with RFC 6125.
+
+JH/07 Bug 2597: Fix a resource leak.  Using a lookup in obtaining a value for
+      smtp_accept_max_per_host allocated resources which were not released
+      when the limit was exceeded.  This eventually crashed the daemon.  Fix
+      by adding a relase action in that path.
+
+JH/08 Bug 2598: Fix verify ACL condition.  The options for the condition are
+      expanded; previously using tainted values was rejected.  Fix by using
+      dynamically-created buffers.
+
+JH/09 Relax restrictions on ACL verify condition needing access to message
+      headers.  Previously they were only permitted in data and non-smtp ACLs;
+      permit also mime, dkim, prdr quit and notquit.  Applies to header-syntax,
+      not_blind, header_sender and header_names_ascii verification.

+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)
