JH/13 Fix dsearch "subdir" filter to ignore ".". Previously only ".." was
excluded, not matching the documentation.
+JH/14 Bug 2606: Fix a segfault in sqlite lookups. When no, or a bad, filename
+ was given for the sqlite_dbfile a trap resulted.
+
+JH/15 Bug 2620: Fix "spam" ACL condition. Previously, tainted values for the
+ "name" argument resulted in a trap. There is no reason to disallow such;
+ this was a coding error.
+
+JH/16 Bug 2615: Fix pause during message reception, on systems that have been
+ suspended/resumed. The Linux CLOCK_MONOTONIC does not account for time
+ spent suspended, ignoring the Posix definition. Previously we assumed
+ it did and a constant offset from real time could be used as a correction.
+ Change to using the same clock source for the start-of-message and the
+ post-message next-tick-wait. Also change to using CLOCK_BOOTTIME if it
+ exists, just to get a clock slightly more aligned to reality.
+
+JH/17 Bug 2295: Fix DKIM signing to always semicolon-terminate. Although the
+ RFC says it is optional some validators care. The missing char was not
+ intended but triggered by a line-wrap alignement. Discovery and fix by
+ Guillaume Outters, hacked on by JH.
+
+JH/18 Bug 2617: Fix a taint trap in parse_fix_phrase(). Previously when the
+ name being quoted was tainted a trap would be taken. Fix by using
+ dynamicaly created buffers. The routine could have been called by a
+ rewrite with the "h" flag, by using the "-F" command-line option, or
+ by using a "name=" option on a control=submission ACL modifier.
+
+JH/21 Bug 2630: Fix eol-replacement string for the ${readsocket } expansion.
+ Previously when a whitespace character was specified it was not inserted
+ after removing the newline.
+
+JH/24 Bug 2634: Fix a taint trap seen on NetBSD: the testing coded for
+ is_tainted() had an off-by-one error in the overenthusiastic direction.
+ Find and fix by Gavan. Although NetBSD is not a supported platform for
+ 4.94 this bug could affect other platforms.

+ Previously when a whitespace character was specified it was not inserted

+
+JH/22 Bug 2265: Force SNI usage for smtp transport DANE'd connections, to be
+ the domain part of the recipient address. This overrides any tls_sni
+ option set, which was previously used.
+
+JH/23 Logging: with the +tls_sni log_selector, do not wrap the received SNI
+ in quotes.
+
+JH/26 Bug 2646: fix a memory usage issue in ldap lookups. Previously, when more
+ than one server was defined and depending on the platform memory layout
+ details, an internal consistency trap could be hit while walking the list
+ of servers.
+
+JH/27 Bug 2648: fix the passing of an authenticator public-name through spool
+ files. The value is used by the authresults expansion item. Previously
+ if this was used in a router or transport, a crash could result.
+
+JH/30 Bug 2677: fix matching of long addresses. Since 4.93 a limit of 256 was
+ applied. This resulted, if any header-line rewrite rules were configured,
+ in a panic-log trigerrable by sending a message with a long address in
+ a header. Fix by increaing the arbitrary limit to larger than a single
+ (dewrapped) 5322 header line maximum size.
+
+JH/31 The ESMTP option name advertised for the SUPPORT_EARLY_PIPE build option
+ is changed from X_PIPE_CONNECT to PIPE_CONNECT. This is in line with
+ RFC 6648 which deprecates X- options in protocols as a general practice.
+ Changeover between the implementations is handled by the mechanisms
+ alrready coded.
+
+JH/32 Bug 2599: fix delay of delivery to a local address where there is also
+ a remote which uses callout/hold. Previously the local was queued.
+
+JH/33 Fix a taint trap in the ${listextract } expansion when the source data
+ was tainted.
+
+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/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/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 2692: 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.
+
+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.
+
+PP/05 Fix security issue CVE-2020-PFPSN and guard against cmdline invoker
+ providing a particularly obnoxious sender full name.
+ Reported by Qualys.
+
+PP/06 Fix CVE-2020-28016 (PFPZA): Heap out-of-bounds write in parse_fix_phrase()
+
+PP/07 Refuse to allocate too little memory, block negative/zero allocations.
+ Security guard.
+
+PP/08 Change default for recipients_max from unlimited to 50,000.
+
+PP/09 Fix security issue with too many recipients on a message (to remove a
+ known security problem if someone does set recipients_max to unlimited,
+ or if local additions add to the recipient list).
+ Fixes CVE-2020-RCPTL reported by Qualys.
+
+PP/10 Fix security issue in SMTP verb option parsing
+ Fixes CVE-2020-EXOPT reported by Qualys.
+
+PP/11 Fix security issue in BDAT state confusion.
+ Ensure we reset known-good where we know we need to not be reading BDAT
+ data, as a general case fix, and move the places where we switch to BDAT
+ mode until after various protocol state checks.
+ Fixes CVE-2020-BDATA reported by Qualys.
