-Change log file for Exim from version 4.21
-------------------------------------------
 This document describes *changes* to previous versions, that might
 affect Exim's operation, with an unchanged configuration file.  For new
 options, and new features, see the NewStuff file next to this ChangeLog.
 
 
+Exim version 4.94
+-----------------
+
+JH/01 Avoid costly startup code when not strictly needed.  This reduces time
+      for some exim process initialisations.  It does mean that the logging
+      of TLS configuration problems is only done for the daemon startup.
+
+JH/02 Early-pipelining support code is now included unless disabled in Makefile.
+
+JH/03 DKIM verification defaults no long accept sha1 hashes, to conform to
+      RFC 8301.  They can still be enabled, using the dkim_verify_hashes main
+      option.
+
+JH/04 Support CHUNKING from an smtp transport using a transport_filter, when
+      DKIM signing is being done.  Previously a transport_filter would always
+      disable CHUNKING, falling back to traditional DATA.
+
+JH/05 Regard command-line receipients as tainted.
+
+JH/06 Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.
+
+JH/07 Bug 2489: Fix crash in the "pam" expansion condition.  It seems that the
+      PAM library frees one of the arguments given to it, despite the
+      documentation.  Therefore a plain malloc must be used.
+
+JH/08 Bug 2491: Use tainted buffers for the transport smtp context.  Previously
+      on-stack buffers were used, resulting in a taint trap when DSN information
+      copied from a received message was written into the buffer.
+
+JH/09 Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix
+      the ordering of its ARC headers.  This caused a crash.
+
+JH/10 Bug 2492: Use tainted memory for retry record when needed.  Previously when
+      a new record was being constructed with information from the peer, a trap
+      was taken.
+

 Exim version 4.93

 HS/05 Handle trailing backslash gracefully. (CVE-2019-15846)
 
+JH/39 Promote DMARC support to mainline.
+
+JH/40 Bug 2452: Add a References: header to DSNs.
+
+JH/41 With GnuTLS 3.6.0 (and later) do not attempt to manage Diffie-Hellman
+      parameters.  The relevant library call is documented as "Deprecated: This
+      function is unnecessary and discouraged on GnuTLS 3.6.0 or later. Since
+      3.6.0, DH parameters are negotiated following RFC7919."
+
+HS/06 Change the default of dnssec_request_domains to "*"
+
+JH/42 Bug 2545: Fix CHUNKING for all RCPT commands rejected.  Previously we
+      carried on and emitted a BDAT command, even when PIPELINING was not
+      active.
+
+JH/43 Bug 2465: Fix taint-handling in dsearch lookup.  Previously a nontainted
+      buffer was used for the filename, resulting in a trap when tainted
+      arguments (eg. $domain) were used.
+
+JH/44 With OpenSSL 1.1.1 (onwards) disable renegotiation for TLS1.2 and below;
+      recommended to avoid a possible server-load attack.  The feature can be
+      re-enabled via the openssl_options main cofiguration option.
+
+JH/45 local_scan API: documented the current smtp_printf() call. This changed
+      for version 4.90 - adding a "more data" boolean to the arguments.
+      Bumped the ABI version number also, this having been missed previously;
+      release versions 4.90 to 4.92.3 inclusive were effectively broken in
+      respect of usage of smtp_printf() by either local_scan code or libraries
+      accessed via the ${dlfunc } expansion item.  Both will need coding
+      adjustment for any calls to smtp_printf() to match the new function
+      signature; a FALSE value for the new argument is always safe.
+
+JH/46 FreeBSD: fix use of the sendfile() syscall.  The shim was not updating
+      the file-offset (which the Linux syscall does, and exim expects); this
+      resulted in an indefinite loop.
+
+JH/47 ARC: fix crash in signing, triggered when a configuration error failed
+      to do ARC verification.  The Authentication-Results: header line added
+      by the configuration then had no ARC item.
+
