       were used, and the second one (for mainlog/paniclog) retrieved null

+JH/20 Taint checking: disallow use of tainted data for
+      - the appendfile transport file and directory options
+      - the pipe transport command
+      - the autoreply transport file, log and once options
+      - file names used by the redirect router (including filter files)
+      - named-queue names
+      Previously this was permitted.
+
+JH/21 Bug 2501: Fix init call in the heimdal authenticator.  Previously it
+      adjusted the size of a major service buffer; this failed because the
+      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 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.
