+Exim version 4.95
+-----------------
+
+JH/01 Bug 1329: Fix format of Maildir-format filenames to match other mail-
+ related applications. Previously an "H" was used where available info
+ says that "M" should be, so change to match.
+
+JH/02 Bug 2587: Fix pam expansion condition. Tainted values are commonly used
+ as arguments, so an implementation trying to copy these into a local
+ buffer was taking a taint-enforcement trap. Fix by using dynamically
+ created buffers.
+
+JH/03 Bug 2586: Fix listcount expansion operator. Using tainted arguments is
+ reasonable, eg. to count headers. Fix by using dynamically created
+ buffers rather than a local. Do similar fixes for ACL actions "dcc",
+ "log_reject_target", "malware" and "spam"; the arguments are expanded
+ so could be handling tainted values.
+
+JH/04 Bug 2590: Fix -bi (newaliases). A previous code rearrangement had
+ broken the (no-op) support for this sendmail command. Restore it
+ to doing nothing, silently, and returning good status.
+
+JH/05 Bug 2593: Fix "vacation" in Exim filter. Previously, when a "once"
+ record path was given (or the default used) without a leading directory
+ path, an error occurred on trying to open it. Use the transport's working
+ directory.
+
+JH/06 Bug 2594: Change the name used for certificate name checks in the smtp
+ transport. Previously it was the name on the DNS A-record; use instead
+ the head of the CNAME chain leading there (if there is one). This seems
+ to align better with RFC 6125.
+
+
Exim version 4.94
-----------------
JH/39 DKIM verification: the RFC 8301 restriction on sizes of RSA keys is now
the default. See the (new) dkim_verify_min_keysizes option.
+JH/40 Fix a memory-handling bug: when a connection carried multiple messages
+ and an ACL use a lookup for checking either the local_part or domain,
+ stale data could be accessed. Ensure that variable references are
+ dropped between messages.
+
+JH/41 Bug 2571: Fix SPA authenticator. Running as a server, an offset supplied
+ by the client was not checked as pointing within response data before
+ being used. A malicious client could thus cause an out-of-bounds read and
+ possibly gain authentication. Fix by adding the check.
+
+JH/42 Internationalisation: change the default for downconversion in the smtp
+ transport to be "if needed". Previously it was "as previously set" for
+ the message, which usually meant "if needed" for message-submission but
+ "no" for everything else. However, MTAs have been seen using SMTPUTF8
+ even when the envelope addresses did not need it, resulting in forwarding
+ failures to non-supporting MTAs. A downconvert in such cases will be
+ a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
+ transport. The change does mean that addresses needing conversion will
+ be converted when previously a delivery failure would occur.
+
+JH/43 Fix possible long line in DSN. Previously when a very long SMTP error
+ response was received it would be used unchecked in a fail-DSN, violating
+ standards on line-length limits. Truncate if needed.
+
+HS/01 Remove parameters of the link to www.open-spf.org. The linked form
+ doesn't work. (Additionally add a new main config option to configure the
+ spf_smtp_comment)
+
Exim version 4.93
-----------------
JH/21 The smtp transport option "hosts_noproxy_tls" is now unset by default.
A single TCP connection by a client will now hold a TLS connection open
- for multiple message deliveries, by default. Previoud the default was to
+ for multiple message deliveries, by default. Previously the default was to
not do so.
JH/22 The smtp transport option "hosts_try_dane" now enables all hosts by
