You will need to rebuild 44 your conversations databases with :cyrusman:`ctl_conversationsdb(8)` and 45 the `-b` switch to benefit from this 46* IMAP FETCH accepts two new data items, MAILBOXIDS and MAILBOXES, which 47 respectively return the unique ids or names of the containing mailboxes of 48 each message in the sequence (for best performance, rebuild your 49 conversations databases as above) 50* :cyrusman:`mbpath(8)` is now much more useful 51* Twoskip database format now supports shared locks, and ensures record 52 headers do not span disk block boundaries 53* All Cyrus binaries now use real sysexits exit codes instead of mapping 54 nearly everything to EX_TEMPFAIL 55* CyrusDB errors now syslog the actual error instead of just "cyrusdb error" 56* New `allowdeleted` :cyrusman:`imapd.conf(5)` option (default off), which 57 allows admin users to see deleted mailboxes and expunged messages over IMAP 58* :cyrusman:`cyr_virusscan(8)` now supports custom templates for notifications 59 sent about infected messages that have been deleted 60* :cyrusman:`imapd.conf(5)` options that represent a time duration now accept 61 'd', 'h', 'm', 's' suffixes rather than arbitrary units 62* The `tls_server_cert` and `tls_server_key` :cyrusman:`imapd.conf(5)` options 63 now allow two certificate/key pairs (e.g. RSA and EC) to be used. Thanks 64 Дилян Палаузов 65* Mailbox create/delete/rename are now performed under a lock on the user's 66 namespace, to prevent races (especially during big renames) 67* The :cyrusman:`cyr_info(8)` `conf-lint` subcommand no longer complains 68 about channel-prefixed sync options 69* New `master_bind_errors_fatal` :cyrusman:`imapd.conf(5)` option (default 70 off), with which master will refuse to start if any of the configured 71 services are unable to successfully bind their port. The default and legacy 72 behaviour is for master to start with the affected services disabled, and 73 not try to start them again until a SIGHUP is received 74* New `autocreate_acl` :cyrusman:`imapd.conf(5)` option, for specifying ACLs 75 to use when mailboxes are created by `autocreate_inbox_folders` 76 77Updates to default configuration 78================================ 79 80The :cyrusman:`cyr_info(8)` `conf`, `conf-all` and `conf-default` subcommands 81now accept an `-s <version>` argument to highlight :cyrusman:`imapd.conf(5)` 82options that are new or whose behaviour has changed since the specified 83version. We recommend using this when evaluating a new Cyrus version to 84check which configuration options you will need to re-examine and maybe change 85during the process. 86 87* The `specialusealways` option is now enabled by default. It must 88 explicitly be disabled for interoperability with legacy clients that 89 can't handle RFC 6154 attributes in extended LIST commands. 90* The values accepted by `expunge_mode` have changed, please see the 91 documentation for more information about the changes. 92* The legacy GETANNOTATIONS/SETANNOTATIONS IMAP commands will no longer 93 work unless `annotation_enable_legacy_commands` is enabled. 94* The `outbox_sendlater` option and its functionality have been removed. 95 96 97Security fixes 98============== 99 100* Contains fix for `CVE-2017-14230 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-14230>`_ 101* Contains fix for `CVE-2019-18928 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-18928>`_ 102* Contains fix for `CVE-2019-19783 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19783>`_ 103 104 105Significant bugfixes 106==================== 107 108* Contains fix for :issue:`2839` 109 110 111.. _Xapian: https://xapian.org 112.. _ClamAV: https://www.clamav.net 113.. _JMAP: http://jmap.io 114
