Changed the runtest perl + script to read through the entire script once to detect and set these + variables, reset to the beginning of the script, and then run through + the script parsing/test process like normal. + +TL/02 The BSD's have an arc4random API. One of the functions to induce + adding randomness was arc4random_stir(), but it has been removed in + OpenBSD 5.5. Detect this OpenBSD version and skip calling this + function when detected. + +JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now + cause callback expansion. + +TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that + syntax errors in an expansion can be treated as a string instead of + logging or causing an error, due to the internal use of bool_lax + instead of bool when processing it. + +JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for + server certificates when making smtp deliveries. + +JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups. + +JH/04 Add ${sort {list}{condition}{extractor}} expansion item. + +TL/04 Bugzilla 1216: Add -M (related messages) option to exigrep. + + +Exim version 4.84 +----------------- +TL/01 Bugzilla 1506: Re-add a 'return NULL' to silence complaints from static + checkers that were complaining about end of non-void function with no + return. + +JH/01 Bug 1513: Fix parsing of quoted parameter values in MIME headers. + This was a regression intruduced in 4.83 by another bugfix. + +JH/02 Fix broken compilation when EXPERIMENTAL_DSN is enabled. + +TL/02 Bug 1509: Fix exipick for enhanced spoolfile specification used when + EXPERIMENTAL_DSN is enabled. Fix from Wolfgang Breyha. + + +Exim version 4.83 +----------------- + +TF/01 Correctly close the server side of TLS when forking for delivery. + + When a message was received over SMTP with TLS, Exim failed to clear up + the incoming connection properly after forking off the child process to + deliver the message. In some situations the subsequent outgoing + delivery connection happened to have the same fd number as the incoming + connection previously had. Exim would try to use TLS and fail, logging + a "Bad file descriptor" error. + +TF/02 Portability fix for building lookup modules on Solaris when the xpg4 + utilities have not been installed. + +JH/01 Fix memory-handling in use of acl as a conditional; avoid free of + temporary space as the ACL may create new global variables. + +TL/01 LDAP support uses per connection or global context settings, depending + upon the detected version of the libraries at build time. + +TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection + to extract and use the src ip:port in logging and expansions as if it + were a direct connection from the outside internet. PPv2 support was + updated based on HAProxy spec change in May 2014. + +JH/02 Add ${listextract {number}{list}{success}{fail}}. + +TL/03 Bugzilla 1433: Fix DMARC SEGV with specific From header contents. + Properly escape header and check for NULL return. + +PP/01 Continue incomplete 4.82 PP/19 by fixing docs too: use dns_dnssec_ok + not dns_use_dnssec. + +JH/03 Bugzilla 1157: support log_selector smtp_confirmation for lmtp. + +TL/04 Add verify = header_names_ascii check to reject email with non-ASCII + characters in header names, implemented as a verify condition. + Contributed by Michael Fischer v. Mollard. + +TL/05 Rename SPF condition results err_perm and err_temp to standardized + results permerror and temperror. Previous values are deprecated but + still accepted. In a future release, err_perm and err_temp will be + completely removed, which will be a backward incompatibility if the + ACL tests for either of these two old results. Patch contributed by + user bes-internal on the mailing list. + +JH/04 Add ${utf8clean:} operator. Contributed by Alex Rau. + +JH/05 Bugzilla 305: Log incoming-TLS details on rejects, subject to log + selectors, in both main and reject logs. + +JH/06 Log outbound-TLS and port details, subject to log selectors, for a + failed delivery. + +JH/07 Add malware type "sock" for talking to simple daemon. + +JH/08 Bugzilla 1371: Add tls_{,try_}verify_hosts to smtp transport. + +JH/09 Bugzilla 1431: Support (with limitations) headers_add/headers_remove in + routers/transports under cutthrough routing. + +JH/10 Bugzilla 1005: ACL "condition =" should accept values which are negative + numbers. Touch up "bool" conditional to keep the same definition. + +TL/06 Remove duplicated language in spec file from 4.82 TL/16. + +JH/11 Add dnsdb tlsa lookup. From Todd Lyons. + +JH/12 Expand items in router/transport headers_add or headers_remove lists + individually rather than the list as a whole. Bug 1452. + + Required for reasonable handling of multiple headers_ options when + they may be empty; requires that headers_remove items with embedded + colons must have them doubled (or the list-separator changed). + +TL/07 Add new dmarc expansion variable $dmarc_domain_policy to directly + view the policy declared in the DMARC record. Currently, $dmarc_status + is a combined value of both the record presence and the result of the + analysis. + +JH/13 Fix handling of $tls_cipher et.al. in (non-verify) transport. Bug 1455. + +JH/14 New options dnssec_request_domains, dnssec_require_domains on the + dnslookup router and the smtp transport (applying to the forward + lookup). + +TL/08 Bugzilla 1453: New LDAP "SERVERS=" option allows admin to override list + of ldap servers used for a specific lookup. Patch provided by Heiko + Schlichting. + +JH/18 New options dnssec_lax, dnssec_strict on dnsdb lookups. + New variable $lookup_dnssec_authenticated for observability. + +TL/09 Bugzilla 609: Add -C option to exiqgrep, specify which exim.conf to use. + Patch submitted by Lars Timman. + +JH/19 EXPERIMENTAL_OCSP support under GnuTLS.
