 Exim version 4.89

+-----------------
 
 JH/01 Bug 1922: Support IDNA2008.  This has slightly different conversion rules
       than -2003 did; needs libidn2 in addition to libidn.

 PP/05 FreeBSD compat: handle that Ports no longer create /usr/bin/perl
 
+JH/16 Drop variables when they go out of scope.  Memory management drops a whole
+      region in one operation, for speed, and this leaves assigned pointers
+      dangling.  Add checks run only under the testsuite which checks all
+      variables at a store-reset and panics on a dangling pointer; add code
+      explicitly nulling out all the variables discovered.  Fixes one known
+      bug: a transport crash, where a dangling pointer for $sending_ip_address
+      originally assigned in a verify callout, is re-used.
+
+PP/06 Drop '.' from @INC in various Perl scripts.
+
+PP/07 Switch FreeBSD iconv to always use the base-system libc functions.
+
+PP/08 Reduce a number of compilation warnings under clang; building with
+      CC=clang CFLAGS+=-Wno-dangling-else -Wno-logical-op-parentheses
+      should be warning-free.
+
+JH/17 Fix inbound CHUNKING when DKIM disabled at runtime.
+
+HS/01 Fix portability problems introduced by PP/08 for platforms where
+      realloc(NULL) is not equivalent to malloc() [SunOS et al].
