For new options, and new features, see the NewStuff file next to this ChangeLog. +Exim version 4.94 +----------------- + +JH/01 Avoid costly startup code when not strictly needed. This reduces time + for some exim process initialisations. It does mean that the logging + of TLS configuration problems is only done for the daemon startup. + +JH/02 Early-pipelining support code is now included unless disabled in Makefile. + +JH/03 DKIM verification defaults no long accept sha1 hashes, to conform to + RFC 8301. They can still be enabled, using the dkim_verify_hashes main + option. + +JH/04 Support CHUNKING from an smtp transport using a transport_filter, when + DKIM signing is being done. Previously a transport_filter would always + disable CHUNKING, falling back to traditional DATA. + +JH/05 Regard command-line receipients as tainted. + +JH/06 Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM. + +JH/07 Bug 2489: Fix crash in the "pam" expansion condition. It seems that the + PAM library frees one of the arguments given to it, despite the + documentation. Therefore a plain malloc must be used. + +JH/08 Bug 2491: Use tainted buffers for the transport smtp context. Previously + on-stack buffers were used, resulting in a taint trap when DSN information + copied from a received message was written into the buffer. + +JH/09 Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix + the ordering of its ARC headers. This caused a crash. + +JH/10 Bug 2492: Use tainted memory for retry record when needed. Previously when + a new record was being constructed with information from the peer, a trap + was taken. + +JH/11 Bug 2494: Unset the default for dmarc_tld_file. Previously a naiive + installation would get error messages from DMARC verify, when it hit the + nonexistent file indicated by the default. Distros wanting DMARC enabled + should both provide the file and set the option. + Also enforce no DMARC verification for command-line sourced messages. + +JH/12 Fix an uninitialised flag in early-pipelining. Previously connections + could, depending on the platform, hang at the STARTTLS response. + + Exim version 4.93 ----------------- @@ -204,6 +250,23 @@ JH/44 With OpenSSL 1.1.1 (onwards) disable renegotiation for TLS1.2 and below; recommended to avoid a possible server-load attack. The feature can be re-enabled via the openssl_options main cofiguration option. +JH/45 local_scan API: documented the current smtp_printf() call. This changed + for version 4.90 - adding a "more data" boolean to the arguments. + Bumped the ABI version number also, this having been missed previously; + release versions 4.90 to 4.92.3 inclusive were effectively broken in + respect of usage of smtp_printf() by either local_scan code or libraries + accessed via the ${dlfunc } expansion item. Both will need coding + adjustment for any calls to smtp_printf() to match the new function + signature; a FALSE value for the new argument is always safe. + +JH/46 FreeBSD: fix use of the sendfile() syscall. The shim was not updating + the file-offset (which the Linux syscall does, and exim expects); this + resulted in an indefinite loop. + +JH/47 ARC: fix crash in signing, triggered when a configuration error failed + to do ARC verification. The Authentication-Results: header line added + by the configuration then had no ARC item. + Exim version 4.92 -----------------
