       API was removed, so update to use the newer ones.

+      any timeout set, is taking a long time.  Previously we would hang on to a
       rotated logfile "forever" if the input was arriving with long gaps
       (a previous attempt to fix addressed lack, for a long time, of initial
       input).
 
+HS/01 Bug 2390: Use message_id for tempfile creation to avoid races in a
+      shared (NFS) environment. The length of the tempfile name is now
+      4 + 16 ("hdr.$message_exim_id") which might break on file
+      systems which restrict the file name length to lower values.

+HS/02 Bug 2392: exigrep does case sensitive *option* processing (as it
+      did for all versions <4.90). Notably -M, -m, --invert, -I may be
+      affected.

+JH/15 Use unsigned when creating bitmasks in macros, to avoid build errors
+      on some platforms for bit 31.
+
+JH/16 GnuTLS: rework ciphersuite strings under recent library versions.  Thanks
+      to changes apparently associated with TLS1.3 handling some of the APIs
+      previously used were either nonfunctional or inappropriate.  Strings
+      like TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM__AEAD:256
+      and TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_128_CBC__SHA256:128 replace
+      the previous TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 .
+      This affects log line X= elements, the $tls_{in,out}_cipher variables,
+      and the use of specific cipher names in the encrypted= ACL condition.
+
+JH/17 OpenSSL: the default openssl_options now disables ssl_v3.
