+Exim version 4.95
+-----------------
+
+JH/01 Move the wait-for-next-tick (needed for unique messmage IDs) from
+      after reception to before a subsequent reception.  This should
+      mean slightly faster delivery, and also confirmation of reception
+      to senders.
+
+JH/02 Move from using the pcre library to pcre2.  The former is no longer
+      being developed or supported (by the original developer).
+
+JH/03 Constification work in the filters module required a major version
+      bump for the local-scan API.  Specifically, the "headers_charset"
+      global which is visible via the API is now const and may therefore
+      not be modified by local-scan code.
+
+JH/04 Fix ClamAV TCP use under FreeBSD. Previously the OS-specific shim for
+      sendfile() didi not account for the way the ClamAV driver code called it.
