affect Exim's operation, with an unchanged configuration file. For new
options, and new features, see the NewStuff file next to this ChangeLog.
-Since 4.95
-----------
+Exim version 4.95
+-----------------
JH/01 Move the wait-for-next-tick (needed for unique messmage IDs) from
- after reception to before a subsequence reception. This should
+ after reception to before a subsequent reception. This should
mean slightly faster delivery, and also confirmation of reception
to senders.
global which is visible via the API is now const and may therefore
not be modified by local-scan code.
+JH/04 Fix ClamAV TCP use under FreeBSD. Previously the OS-specific shim for
+ sendfile() didi not account for the way the ClamAV driver code called it.
+
+JH/05 Bug 2819: speed up command-line messages being read in. Previously a
+ time check was being done for every character; replace that with one
+ per buffer.
+
+JH/06 Bug 2815: Fix ALPN sent by server under OpenSSL. Previously the string
+ sent was prefixed with a length byte.
+
+JH/07 Change the SMTP feature name for pipelining connect to be compliant with
+ RFC 5321. Previously Dovecot (at least) would log errors during
+ submission.
+
+JH/08 Remove stripping of the binaries from the FreeBSD build. This was added
+ in 4.61 without a reason logged. Binaries will be bigger, which might
+ matter on diskspace-constrained systems, but debug is easier.
+
+JH/09 Fix macro-definition during "-be" expansion testing. The move to
+ write-protected store for macros had not accounted for these runtime
+ additions; fix by removing this protection for "-be" mode.
+
+JH/10 Convert all uses of select() to poll(). FreeBSD 12.2 was found to be
+ handing out large-numbered file descriptors, violating the usual Unix
+ assumption (and required by Posix) that the lowest possible number will be
+ allocated by the kernel when a new one is needed. In the daemon, and any
+ child procesees, values higher than 1024 (being bigger than FD_SETSIZE)
+ are not useable for FD_SET() [and hence select()] and overwrite the stack.
+ Assorted crashes happen.
+
+JH/11 Fix use of $sender_host_name in daemon process. When used in certain
+ main-section options or in a connect ACL, the value from the first ever
+ connection was never replaced for subsequent connections. Found by
+ Wakko Warner.
+
+JH/12 Bug 2838: Fix for i32lp64 hard-align platforms. Found for SPARC Linux,
+ though only once PCRE2 was introduced: the memory accounting used under
+ debug offset allocations by an int, giving a hard trap in early startup.
+ Change to using a size_t. Debug and fix by John Paul Adrian Glaubitz.
+
+JH/13 Bug 2845: Fix handling of tls_require_ciphers for OpenSSL when a value
+ with underbars is given. The write-protection of configuration introduced
+ in 4.95 trapped when normalisation was applied to an option not needing
+ expansion action.
+
+JH/14 Bug 1895: TLS: Deprecate RFC 5114 Diffie-Hellman parameters.
+
+JH/15 Fix a resource leak in *BSD. An off-by-one error resulted in the daemon
+ failing to close the certificates directory, every hour or any time it
+ was touched.
+
+JH/16 Debugging initiated by an ACL control now continues through into routing
+ and transport processes, when delivery is immediate. Previously debugging
+ stopped any time Exim re-execs.
+
+JH/17 The "expand" debug selector now gives more detail, specifically on the
+ result of expansion operators and items.
+
+JH/18 Bug 2751: Fix include_directory in redirect routers. Previously a
+ bad comparison between the option value and the name of the file to
+ be included was done, and a mismatch was wrongly identified.
+ 4.88 to 4.95 are affected.
+
+JH/19 Support for Berkeley DB versions 1 and 2 is withdrawn.
+
+JH/20 When built with NDBM for hints DB's check for nonexistence of a name
+ supplied as the db file-pair basename. Previously, if a directory
+ path was given, for example via the autoreply "once" option, the DB
+ file.pag and file.dir files would be created in that directory's
+ parent.
+
+JH/21 Remove the "allow_insecure_tainted_data" main config option and the
+ "taint" log_selector. These were previously deprecated.
+
+JH/22 Fix static address-list lookups to properly return the matched item.
+ Previously only the domain part was returned.
+
Exim version 4.95
-----------------
to do ARC verification. The Authentication-Results: header line added
by the configuration then had no ARC item.
+JH/48 Bug 2784: fix shutdown=no in the ${readsocket) expansion item. Previously
+ an incorrect mode was used for reading the result, resulting in it being
+ ignored.
+
Exim version 4.92
-----------------
