+Version 4.93
+------------
+
+ 1. An "external" authenticator, per RFC 4422 Appendix A.
+
+ 2. A JSON lookup type, and JSON variants of the forall/any expansion conditions.
+
+ 3. Variables $tls_in_cipher_std, $tls_out_cipher_std giving the RFC names
+    for ciphersuites.
+
+ 4. Log_selectors "msg_id" (on by default) and "msg_id_created".
+
+ 5. A case_insensitive option for verify=not_blind.
+
+ 6. EXPERIMENTAL_TLS_RESUME optional build feature.  See the experimental.spec
+    file.
+
+ 7. A main option exim_version to override the version Exim
+    reports in verious places ($exim_version, $version_number).
+
+ 8. Expansion operator ${sha2_N:} for N=256, 384, 512.
+
+ 9. Router variables, $r_... settable from router options and usable in routers
+    and transports.
+
+10. The spf lookup now supports IPv6.
+
+11. Main options for DKIM verify to filter hash and key types.
+
+12. Under GnuTLS, with TLS1.3, support for full-chain OCSP stapling.
+
+13. Dual-certificate stacks on servers now support OCSP stapling, under OpenSSL.
+
+
+Version 4.92
+--------------
+
+ 1. ${l_header:<name>} and ${l_h:<name>} expansion items, giving a colon-sep
+    list when there are multiple headers having a given name.  This matters
+    when individual headers are wrapped onto multiple lines; with previous
+    facilities hard to parse.
+
+ 2. The ${readsocket } expansion item now takes a "tls" option, doing the
+    obvious thing.
+
+ 3. EXPERIMENTAL_REQUIRETLS and EXPERIMENTAL_PIPE_CONNECT optional build
+    features.  See the experimental.spec file.
+
+ 4. If built with SUPPORT_I18N a "utf8_downconvert" option on the smtp transport.
+
+ 5. A "pipelining" log_selector.
+
+ 6. Builtin macros for supported log_selector and openssl_options values.
+
+ 7. JSON variants of the ${extract } expansion item.
+
+ 8. A "noutf8" debug option, for disabling the UTF-8 characters in debug output.
+
+ 9. TCP Fast Open support on MacOS.
