@@ -100,13 +100,36 @@ JH/21 Bug 2501: Fix init call in the heimdal authenticator.  Previously it
       buffer was in use at the time.  Change to a compile-time increase in the
       buffer size, when this authenticator is compiled into exim.
 
-JH/22 Taint checking: move to a hybrid approach for checking.  Previously, one
-      of two ways was used, depending on a build-time flag.  The fast method
-      relied on assumptions about the OS and libc malloc, which were known to
-      not hold for the BSD-derived platforms, and discovered to not hold for
-      32-bit Linux either.  In fact the glibc documentation describes cases
-      where these assumptions do not hold.  The new implementation tests for
-      the situation arising and actively switches over from fast to safe mode.
+JH/22 Taint-checking: move to safe-mode taint checking on all platforms.  The
+      previous fast-mode was untenable in the face of glibs using mmap to
+      support larger malloc requests.
+
+PP/01 Update the openssl_options possible values through OpenSSL 1.1.1c.
+      New values supported, if defined on system where compiled:
+      allow_no_dhe_kex, cryptopro_tlsext_bug, enable_middlebox_compat,
+      no_anti_replay, no_encrypt_then_mac, prioritize_chacha, tlsext_padding
+
+JH/23 Performance improvement in the initial phase of a two-pass queue run.  By
+      running a limited number of proceses in parallel, a benefit is gained. The
+      amount varies with the platform hardware and load.  The use of the option
+      queue_run_in_order means we cannot do this, as ordering becomes
+      indeterminate.
+
+JH/24 Bug 2524: fix the cyrus_sasl auth driver gssapi usage.  A previous fix
+      had introduced a string-copy (for ensuring NUL-termination) which was not
+      appropriate for that case, which can include embedded NUL bytes in the
+      block of data.  Investigation showed the copy to actually be needless, the
+      data being length-specified.
+
+JH/25 Fix use of concurrent TLS connections under GnuTLS.  When a callout was
+      done during a receiving connection, and both used TLS, global info was
+      used rather than per-connection info for tracking the state of data
+      queued for transmission.  This could result in a connection hang.
+
+JH/26 Fix use of the SIZE parameter on MAIL commands, on continued connections.
+      Previously, when delivering serveral messages down a single connection
+      only the first would provide a SIZE.  This was due to the size information
+      not being properly tracked.
