+Exim version 4.93+fixes
+-----------------------
+This is not an official release. It is just a branch, collecting
+proposed bugfixes. Depending on your environment the fixes may be
+necessary to build and/or run Exim successfully.
+
+JH/05 Regard command-line receipients as tainted.
+
+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.

@@ -213,6 +237,14 @@ JH/45 local_scan API: documented the current smtp_printf() call. This changed
       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.
