JH/35 Bug 2343: Harden exim_tidydb against corrupt wait- files.
+JH/36 Bug 2687: Fix interpretation of multiple ^ chars in a plaintext
+ authenticator client_send option. Previously the next char, after a pair
+ was collapsed, was taken verbatim (so ^^^foo became ^^foo; ^^^^foo became
+ ^^\x00foo). Fixed to get ^\x00foo and ^^foo respectively to match the
+ documentation. There is still no way to get a leading ^ immediately
+ after a NUL (ie. for the password of a PLAIN method authenticator.
+
+JH/37 Enforce the expected size, for fixed-size records read from hints-DB
+ files. For bad sizes read, delete the record and whine to paniclog.
+
+JH/38 When logging an AUTH failure, as server, do not include sensitive
+ information. Previously, the credentials would be included if given
+ as part of the AUTH command line and an ACL denied authentidcation.
+
+JH/39 Bug 2691: fix $local_part_data. When the matching list element
+ referred to a file, bad data was returned. This likely also affected
+ $domain_part_data.
+
+JH/40 The gsasl authenticator now supports caching of the salted password
+ generated by the client-side implementation. This required the addition
+ of a new variable: $auth4.
+
+JH/41 Fix daemon SIGHUP on FreeBSD. Previously, a named socket for IPC was
+ left undeleted; the attempt to re-create it then failed - resulting in
+ the usual "SIGHUP tp have daemon reload configuration" to not work.
+ This affected any platform not supporting "abstract" Unix-domain
+ sockets (i.e. not Linux).
+
+JH/42 Bug 2693: Harden against a peer which reneges on a 452 "too many
+ recipients" response to RCPT in a later response, with a 250. The
+ previous coding assumed this would not happen, and under PIPELINING
+ would result in both lost and duplicate recipients for a message.
+
+JH/43 Bug 2694: Fix weighted distribution of work to multiple spamd servers.
+ Previously the weighting was incorrectly applied. Similar fix for socks
+ proxies. Found and fixed by Heiko Schlichting.
+
+JH/44 Bug 2701: Fix list-expansion of dns_ipv4_lookup. Previously, it did
+ not handle sub-lists included using the +namedlist syntax. While
+ investigating, the same found for dns_trust_aa, dns_again_means_nonexist,
+ dnssec_require_domains, dnssec_request_domains, srv_fail_domains,
+ mx_fail_domains.
+
+JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
+ Previously the permanent pool was used, so the sore could not be freed.
+ This meant a connection with many messages would use continually-growing
+ memory.
+
+JH/46 Use an exponentially-increasing block size when malloc'ing store. Do it
+ per-pool so as not to waste too much space. Previously a constant size
+ was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+ DOS attacks harder. The cost is wasted memory use in the larger blocks.
+
+JH/47 Use explicit alloc/free for DNS lookup workspace. This permits using the
+ same space repeatedly, and a smaller process footprint.
+
+JH/48 Use a less bogus-looking filename for a temporary used for DH-parameters
+ for GnuTLS. Previously the name started "%s" which, while not a bug,
+ looked as if if might be one.
+
+JH/49 Bug 2710: when using SOCKS for additional messages after the first (a
+ "continued connection") make the $proxy_* variables available. Previously
+ the information was not passed across the exec() call for subsequent
+ transport executions. This also mean that the log lines for the
+ messages can show the proxy information.
+
+JH/50 Bug 2672: QT elements in log lines, unless disabled, now exclude the
+ receive time. With modern systems the difference is significant.
+ The historical behaviour can be restored by disabling (a new) log_selector
+ "queue_time_exclusive".
+
+JH/51 Taint-check ACL line. Previously, only filenames (for out-of-line ACL
+ content) were specifically tested for. Now, also cover epxansions
+ rerulting in acl names and inline ACL content.
+
+JH/52 Fix ${ip6norm:} operator. Previously, any trailing line text was dropped,
+ making it unusable in complex expressions.
+
+JH/53 Bug 2743: fix immediate-delivery via named queue. Previously this would
+ fail with a taint-check on the spoolfile name, and leave the message
+ queued.
+
+HS/01 Enforce absolute PID file path name.
+
+HS/02 Handle SIGINT as we handle SIGTERM: terminate the Exim process.
+
+PP/01 Add a too-many-bad-recipients guard to the default config's RCPT ACL.
+
+PP/02 Bug 2643: Correct TLS DH constants.
+ A missing NUL termination in our code-generation tool had led to some
+ incorrect Diffie-Hellman constants in the Exim source.
+ Reported by kylon94, code-gen tool fix by Simon Arlott.
+
+PP/03 Impose security length checks on various command-line options.
+ Fixes CVE-2020-SPRSS reported by Qualys.
+
+PP/04 Fix Linux security issue CVE-2020-SLCWD and guard against PATH_MAX
+ better. Reported by Qualys.
