This file lists incompatible changes and additional/new features made to mutt. Please read this file carefully when upgrading your installation. The description of changes are intentionally brief. For a more detailed explanation of features, please refer to the manual at http://www.mutt.org/doc/manual/ and the release notes at http://www.mutt.org/relnotes/ The keys used are: !: modified feature, -: deleted feature, +: new feature 2.2.12 (2023-09-09): ! Bug fix release. 2.2.11 (2023-08-18): ! Bug fix release. 2.2.10 (2023-03-25): ! Bug fix release. ! $message_id_format %r and %z expandos use a URL-safe Base64 encoding: '-' and '_' instead of '+' and '/'. 2.2.9 (2022-11-12): ! Bug fix release. 2.2.8 (2022-11-05): ! Bug fix release. ! Ncurses now uses ioctl for window size calculation. Previously, Mutt and ncurses differed on this, which could result in screen corruption in some cases. ! The index now handles resizes without recalculating the top line, as other menus in Mutt do. This should reduce the "jumbling around" visual effect during resizes. + IMAP Fcc is now supported in batch mode. ! In batch mode with $fcc_before_send set, Mutt will abort sending if one or more of the Fcc's fails. 2.2.7 (2022-08-07): ! Bug fix release. ! $query_command output is more strictly parsed, with one tab expected between fields. This allows the name field to be empty. ! $pager may contain a %s to specify the argument placement. 2.2.6 (2022-06-05): ! Bug fix release. 2.2.5 (2022-05-16): ! Bug fix release. 2.2.4 (2022-04-30): ! Path variables (DT_PATH) are normalized to remove a trailing '/'. ! If $header_cache is used as a directory, the directory must already exist or else it will be interpreted as a file. 2.2.3 (2022-04-12): ! Bug fix release. 2.2.2 (2022-03-25): ! Bug fix release. 2.2.1 (2022-02-19): ! Bug fix release. 2.2.0 (2021-02-12): + $pager_skip_quoted_context determines the number of lines to show before unquoted text when using in the pager. ! Quadoption prompts and a few boolean prompts now have a '?' choice, which will display the associated configuration variable. ! , , and can be bound to separate functions/macros. + $sort_thread_groups can be used to sort top-level thread groups differently than subthreads. ! contrib/smime.rc now uses the cms utility for SMIME encryption/decryption. + $compose_confirm_detach_first helps prevent accidentally deleting your typed message in the compose menu. + The $attach_save_charset_convert quadoption prompts to allow charset conversion of received text-type attachments when saving them to disk. + --with-gsasl allows configuration with the GNU SASL library, as an alternative to Cyrus. ! $reply_regexp is now localizable by translators, to add other non-standard prefixes used in the locale. "aw" was removed from the default value. ! $rfc2047_parameters is enabled by default. 2.1.5 (2021-12-30): ! Bug fix release. 2.1.4 (2021-12-11): ! Bug fix release. 2.1.3 (2021-09-10): ! Bug fix release. 2.1.2 (2021-08-24): ! Bug fix release. 2.1.1 (2021-07-12): ! Bug fix release. 2.1.0 (2021-06-12): ! The -d option allows a negative number. If negative, debug files are not rotated. The debug level is the absolute value. + in the attachment menu uses a copiousoutput mailcap entry, or falls back to raw text. + , , and functions added to the compose menu. + in the compose menu allows previewing the output of the $send_multipart_alternative_filter the way does. + , bound to Esc-L in the index and pager menu, brings up a menu of operations to perform on mailing list emails, such as subscribe/unsubscribe. + , bound to 'H' in the pager, will skip to the first blank line following the headers. ! ~h patterns over IMAP and POP3 will only download the headers of the message. However with message caching enabled (via $message_cachedir) the whole message will still be downloaded. + $ssl_verify_host_override allows manually specifying the host name to verify a server certificate against. ! --enable-hcache, with no particular backend enabled, will scan in the order: kyotocabinet, tokyocabinet, lmdb, qdbm, gdbm, bdb. ! $allow_ansi understands 256-color ANSI escape sequences. + $message_id_format can be used to specify a custom message-id format. Since it's a format string, this can also use a filter. Please use this option with care, as Mutt won't check if your message-id is legal. ! mailboxes -nonotify will poll a mailbox for new mail, but will not trigger new mail notifications (e.g. $beep_new or $new_mail_command). ! $reverse_name affects tagged reply/forward/compose-to-sender actions too. ! ANSI sequences are filtered for inline-forwarded autoview content, in addition to replies. ! $forward_decrypt is now a quadoption, defaulting 'yes' for backward compatibility. ! Pattern functions, (e.g. search and limit) can be interrupted with ctrl-c. ! The default mailto_allow list now includes cc, in-reply-to, and references. + $sort_browser_mailboxes controls mailbox browsing, and defaults "unsorted". $sort_browser now only controls directory browsing. ! $sort_browser and $sort_browser_mailboxes "unsorted" now means the order added (e.g. specified in the muttrc). Switching back to "unsorted" will now resort in that order (previously it was a no-op.) ! In the browser ".." is excluded from sorting and kept at the top. ! Temp filenames generated for mailcap invocation now allow non-ascii characters. + $local_date_header, when unset, causes the date in the Date header to be formatted using the GMT timezone. 2.0.7 (2021-05-04): ! Bug fix release. 2.0.6 (2021-03-06): ! Bug fix release. 2.0.5 (2021-01-21): ! Bug fix release. 2.0.4 (2020-12-30): ! Bug fix release. 2.0.3 (2020-12-04): ! Bug fix release. ! Some bugs with exact-address handling were fixed. The "personal" field was not properly updated in some case. The fix may result in behavior changes for those who have enabled this mode; most notably in alias creation, the query menu, $from + $realname setting, and unset $reverse_realname handling. 2.0.2 (2020-11-20): ! Bug fix release. 2.0.1 (2020-11-14): ! Bug fix release. 2.0.0 (2020-11-07): + Domain-literal support for email addresses, e.g user@[IPv6:fcXX:...] ! Buffy completion only occurs for the "change-folder" set of functions. It has been disabled for , , the fcc mailbox prompt, and the autocrypt scan mailbox prompt. ! The "save/copy message to mailbox" set of functions use the "mailbox" history list, instead of the "filename" list. ! Message-ID extraction permits values missing angle brackets and '@' to allow properly threading the garbage sent by some providers. Mutt will add missing angle brackets when sending out replies, however. ! When adding multiple attachments, via in the compose menu, the browser menu can be exiting via after tagging the files. Previously, had to be used. ! ctrl-p/ctrl-n are by default bound to / in the editor menu. + The "cd" command allows changing the current working directory. As part of this, Mutt expands relative paths internally. There may be a change to some "prettified" relative paths because of this. ! Some configuration variable default values are localizable by translators. Currently these are: $attribution, $compose_format, $forward_attribution_intro, $forward_attribution_trailer, $status_format, $ts_icon_format, $ts_status_format. + Mutt will try to automatically reconnect to an IMAP mailbox on error, and will merge unsync'ed changes if possible. ! $crypt_protected_headers_subject defaults to "...", following the protected headers revised specification. ! Date, From, To, Cc, and Reply-To headers are stored as protected headers. + XOAUTH2 support. Please see the manual, contrib script mutt_oauth2.py, and mutt_oauth.py.README for more details. + $tunnel_is_secure, default set, assumes a connection via $tunnel is encrypted. Unsetting this will cause $ssl_starttls and $ssl_force_tls to be respected. + Patterns are completable in the editor menu. Invoke the function (by default bound to Tab) after typing ~ to get a selectable list. ! $reply_to is consulted before $reply_self. + $copy_decode_weed, default unset, controls header weeding for and . + $pipe_decode_weed, default set, enables header weeding for . + $print_decode_weed, default set, enables header weeding for . ! format=flowed attachments are space-unstuffed when viewed, saved, piped, and printed. + The "run" command will execute MuttLisp. $muttlisp_inline_eval, if set, will execute unquoted parenthesized command arguments as MuttLisp. Please see the manual for more details about both. + $cursor_overlay, when set, will overlay the indicator, tree, sidebar_highlight, and sidebar_indicator colors onto the current line. "default" colors will be overridden and attributes will be merged. ! The message-id generation algorithm uses a random number instead of the step counter and PID. ! $ssl_force_tls defaults set. (Trying this again for 2.0). ! $hostname is set *after* muttrc processing. It can be manually set in the muttrc to avoid using DNS calls to obtain the FQDN. + $attach_save_dir specifies a directory to use when saving attachments. 1.14.7 (2020-08-29): ! Bug fix release. 1.14.6 (2020-07-11): ! Bug fix release. 1.14.5 (2020-06-23): ! Bug fix release. - $ssl_starttls no longer controls aborting an unencrypted IMAP PREAUTH connection. Only $ssl_force_tls does this. Mutt highly recommends setting $ssl_force_tls if you rely on STARTTLS. ! Using a $tunnel is considered secure, and will not consult $ssl_force_tls for an unencrypted IMAP PREAUTH connection. 1.14.4 (2020-06-18): ! Bug fix release. 1.14.3 (2020-06-14): ! Bug fix release. ! $ssl_starttls and $ssl_force_tls also control aborting an unencrypted IMAP PREAUTH connection. 1.14.2 (2020-05-25): ! Bug fix release. 1.14.1 (2020-05-16): ! Bug fix release. 1.14.0 (2020-05-02): + $imap_deflate enables support for COMPRESS=DEFLATE compression. Defaults unset, but please give it a try and report any issues. ! Date pattern modifiers accept YYYYMMDD format dates. + $crypt_opportunistic_encrypt_strong_keys modifies $crypt_opportunistic_encrypt to only look at strong (fully-valid) keys. ! Pattern modifiers ~b, ~B, and ~h are allowed in send2-hook patterns. + New compose menu functions and to rearrange the order parts. + Background editing support. Compose and browse your mailbox at the same time, or have multiple compose sessions ongoing! New config vars $background_edit, $background_confirm_quit, and $background_format. New function in the index and pager menu. New %B expando added to the default for $status_format. Please see the manual and release notes for details. + $fcc_delimiter, when set, allows Fcc'ing to multiple mailboxes via $record or fcc-hook. + Index and pager menu functions and . ! "mailboxes -label" allows displaying a label in the sidebar or mailbox browser instead of the mailbox path. "-nolabel" removes an existing label. ! "mailboxes -nopoll" turn off new mail polling for the mailbox. "-poll" restores polling for an existing mailbox. ! "root" disposition added to the "attachments" command. Please see the manual for the details of how it works. ! Decryption failures will no longer abort the displaying the pager. ! With "exact address" enabled, mailboxes that contain non-ascii characters, or sequences that require RFC 2047 encoding, will be written in normalized "Name " form when sending emails, so that they can be properly RFC 2047 and IDNA encoded. 1.13.5 (2020-03-28): ! Bug fix release. 1.13.4 (2020-02-15): ! Bug fix release. ! $ssl_force_tls reverted to default unset. Defaulting this set was overly optimistic, and caused breakage. 1.13.3 (2020-01-12): ! Bug fix release. 1.13.2 (2019-12-18): ! Bug fix release. 1.13.1 (2019-12-14): ! Bug fix release. + $sidebar_relative_shortpath_indent, default unset, enables the indentation and shortpath behavior introduced in 1.13.0. + $sidebar_use_mailbox_shortcuts, default unset, displays standard mailbox shortcuts, '~' and '=' in the sidebar. When unset, the sidebar will remove a $folder prefix but won't display mailbox shortcuts. 1.13.0 (2019-11-30): ! and in the pager are now symmetric. ! $ssl_force_tls is now set by default. ! Configure option --with-regex is renamed to --with-bundled-regex. Most modern OS should be fine using their own regex library. The rename is to clarify the intention of the option. ! Configure option --disable-doc now only disables the manual generation. Other parts of the doc directory (man pages, Muttrc file) are generated. ! $user_agent is now unset by default. ! unattachments now has a '*' parameter to remove all attachment counting. + Autocrypt support. Enabled via configure option --enable-autocrypt. Please see the manual for details on how to enable and use this properly. + Byte size displays can be customized via new variables $size_show_bytes, $size_show_mb, $size_show_fractions, $size_units_on_left. + $ssl_use_tlsv1_3, default set, allows TLS1.3 connections if supported by the server. ! format=flowed space stuffing works again, and is performed after every edit, not just the first time. + $browser_sticky_cursor, default set, attempts to keep the cursor on the same mailbox when performing operations in the browser. ! in the browser menu shows the full path for local and IMAP mailboxes. ! $sidebar_folder_indent and $sidebar_short_path are now based on previous entries in the sidebar, allowing them to work on mailboxes outside $folder. ! Sidebar entries are now prefixed with mailbox shortcuts '~' and '='. This uses the same code as other parts of mutt, for more consistent display. + allows direct access to the mailboxes list from the index and pager, without having to use a macro. This improves $browser_sticky_cursor initial selection of the current mailbox. ! with $pipe_decode set will update MIME headers to decoded text/plain values. + $send_multipart_alternative and $send_multipart_alternative_filter allow the generation of a multipart/alternative when composing a message. See their documentation in the manual for more details. Also see contrib/markdown2html for a sample filter. + In the compose menu , , allow previewing the output of the $send_multipart_alternative_filter. ! $write_bcc now defaults unset. It no longer affects the Fcc copy, which will always include the Bcc header. + When $count_alternatives is set, Mutt will recurse inside multipart/alternatives while performing attachment searching and counting. This affects %X in the index and ~X pattern matching. 1.12.2 (2019-09-21): ! Bug fix release. 1.12.1 (2019-06-15): ! Bug fix release. + $fcc_before_send, when set, causes Fcc to occur before sending instead of afterwards. When set, the message is saved as-sent; please see the documentation for details. 1.12.0 (2019-05-25) ! $ssl_use_tlsv1 and $ssl_use_tlsv1_1 now default to unset. + $auto_subscribe, when set, automatically adds an email with the List-Post header to the subscribe list. ! Fcc now occurs after sending a message. If the fcc fails, mutt will prompt to try again, or to try another mailbox. + Basic protected header ("memory hole") support added for the Subject header. See the config vars: $crypt_protected_headers_read, $crypt_protected_headers_save, $crypt_protected_headers_subject, and $crypt_protected_headers_write. ! Color names can be prefixed with "light" in addition to "bright". "bright" colors are bold face, while "light" are non-bold. ! Color commands can now include an attribute (e.g. bold, underline). ! $pgp_use_gpg_agent defaults set. + in the browser menu allows entering nested maildir directories. + replies to all, but preserves To recipients in the reply. + $include_encrypted, default unset, prevents separately encrypted contents from being included in a reply. This helps to prevent a decryption oracle attack. ! With gpgme >= 1.11, recipient keys with a trailing '!' now force subkey use, as with classic gpg. ! In send mode, %{charset} mailcap expansion uses the current charset of the file. + $imap_fetch_chunk_size allows fetching new headers in groups of this size. This might help with timeouts during opening of huge mailboxes. If you have huge mailboxes, you should also try $imap_qresync. ! can be invoked from the pager too. + The $forward_attachments quadoption allows including attachments in inline-forwards (i.e. $mime_forward unset, $forward_decode set.) 1.11.4 (2019-03-13): ! Bug fix release. 1.11.3 (2019-02-01): ! Bug fix release. 1.11.2 (2019-01-07): ! Bug fix release. 1.11.1 (2018-12-01): ! Bug fix release. ! IMAP retrieves the Sender header by default. It doesn't need to be added to $imap_headers. 1.11.0 (2018-11-25): + inotify is used for local mailbox monitoring on Linux. Configuration flag --disable-filemonitor turns this off. + OAUTHBEARER support for IMAP, SMTP and POP via $imap_oauth_refresh_command, $smtp_oauth_refresh_command, and $pop_oauth_refresh_command. ! $pgp_timeout and $smime_timeout support 32-bit numbers. + manually updates mailbox statistics, the same way $mail_check_stats does when set. ! Thread limited views, e.g. ~(pattern), now show new mail as it arrives. ! Command line argument -z and -Z options also work for IMAP mailboxes. + $imap_condstore and $imap_qresync enable IMAP CONDSTORE and QRESYNC support, respectively. QRESYNC should provide much faster mailbox opening. ! $abort_noattach skips quoted lines (as defined by $quote_regexp and $smileys). ! Initial IMAP header downloading can be aborted with ctrl-c. + composes a message to the sender of the selected message, in the index or attachment menu. ! Address book queries ($query_format) now support multibyte characters. + Finnish translation. ! pgpring has been renamed to mutt_pgpring. ! Certificate prompts show sha-256 instead of md5 fingerprints. ! Non-threaded $sort_aux "reverse-" settings now work properly. + The manual can be generated and installed in GNU Info format. + index-format-hook and the new %@name@ expando for $index_format enable dynamic index formats using pattern matching against the current message. This can be used, for example, to format dates based on the age of the message. ! Relative date matching allows hour, minute, and second units: HMS. 1.10.1 (2018-07-16): ! Bug fix release. + $pgp_check_gpg_decrypt_status_fd, when set (the default), checks GnuPG status fd output more thoroughly for spooofed encrypted messages. Please see contrib/gpg.rc for suggested values. 1.10.0 (2018-05-19): ! $reply_self is now respected for group-reply, even with $metoo unset. ! Enabled $imap_poll_timeout when $imap_idle is set. ! Added %R (number of read messages) expando for $status_format. + When $change_folder_next is set, the function mailbox suggestion will start at the next folder in your "mailboxes" list, instead of starting at the first folder in the list. + $new_mail_command specifies a command to run after a new message is received. + $pgp_default_key specifies the default key-pair to use for PGP operations. It will be used for both encryption and signing (unless $pgp_sign_as is set). See contrib/gpg.rc. ! $smime_default_key now specifies the default key-pair to use for both encryption and signing S/MIME operations. See contrib/smime.rc. + $smime_sign_as can be used to specify a sign-only key-pair for S/MIME operations. - $pgp_self_encrypt_as is now deprecated, and is an alias for $pgp_default_key. $smime_self_encrypt_as is also deprecated, and is an alias for $smime_default_key. ! $pgp_self_encrypt and $smime_self_encrypt now default to set. This makes setting $pgp_default_key or $smime_default_key all that is required to enable self-encryption (for both classic and GPGME mode). + The function (default: ^R) will search history based on the text currently typed in. That is, type the search string first, then hit ^R. + The $abort_noattach quadoption controls whether to abort sending a message that matches $abort_noattach_regexp and has no attachments. + Mutt can now be configured --with-idn2. This requires the libidn1 compatibility layer present in libidn2 v2.0.0 or greater. + Unsetting $browser_abbreviate_mailboxes turns off '=' and '~' shortcuts for mailbox names in the browser mailbox list. ! $sort_browser now has 'count' and 'unread' options. + will display the last $error_history count of error/informational messages generated. + The ~M pattern matches content-type headers. Note that this pattern may be slow because it reads each message in. + The "echo" command can be used to display a message, for instance when running a macro or sourcing a file. 1.9.5 (2018-04-14): ! Bug fix release. 1.9.4 (2018-03-03): ! Bug fix release. 1.9.3 (2018-01-27): ! Bug fix release. 1.9.2 (2017-12-15): ! Bug fix release. 1.9.1 (2017-09-23): ! Bug fix release. 1.9.0 (2017-09-02): + $ssl_verify_partial_chains permits verifying partial certificate chains. This allows the storage of only intermediate/host certificates in the $certificate_file. (OpenSSL 1.0.2b and newer only) ! SNI support added for OpenSSL and GnuTLS. + Choice and confirmation prompts can now wrap across multiple lines. + Window resizes are handled while in the line editor. + "color compose" can color the compose menu header fields and the security status. See "Using Color and Mono Video Attributes" in the manual for more details. + Setting $header_color_partial allows partial coloring of headers in the pager. This can be used to color just the header labels, or strings inside the headers. hdrdefault controls the color of the unmatched part. + When $history_remove_dups is set, duplicates in the history ring will be scanned and removed each time a new entry is added. ! IMAP header downloading was improved to support out-of-order and missing MSN entries. ! $message_cache_clean should be faster for large mailboxes. + Self-encryption can be enabled using the $pgp_self_encrypt, $pgp_self_encrypt_as, $smime_self_encrypt, and $smime_self_encrypt_as options. ! $postpone_encrypt now will use the $pgp_self_encrypt_as or $smime_self_encrypt_as option values first. $postpone_encrypt_as will be checked second, but should be considered deprecated. + $forward_attribution_intro and $forward_attribution_trailer can be used to customize the message preceding and following a forwarded message. + The ~<() and ~>() pattern modifiers match messages whose immediate parent, or immediate children respectively, match the subpattern inside (). They are more specific versions of the ~() pattern modifier. + $imap_poll_timeout allow IMAP mailbox polling to time out. This defaults to 15 seconds. + The attachment menu now supports nested encryption. This allows attachments in nested encrypted messages to be saved or operated on. + $mime_type_query_command specifies a command to run to determine a new attachment's mime type. When $mime_type_query_first is set, this command will be run before looking at the mime.types file. 1.8.3 (2017-05-30): ! Bug fix release. 1.8.2 (2017-04-18): ! Bug fix release. 1.8.1 (2017-04-13): ! Bug fix release. 1.8.0 (2017-02-24): - $locale has been removed. Mutt now respects the LC_TIME setting instead. See also $attribution_locale. + $attribution_locale can be used to override the date formatting in attribution strings. When unset, Mutt will use the locale environment, but note the default value of $date_format has a leading '!' which says to use the C-locale. ! Message-id and mail-followup-to headers are now preserved for recalled messages. + added to complement . ! The pager position is reset to the top when toggling header-weed. ! IMAP messages moved to $trash via server-side copy are marked as read. + jumps to the root message of a thread. ! Piped text attachments are charset converted. + Added %F to $attach_format, to show the content-disposition filename. %d will fall back to %F which will fall back to %f. + allows an attachment name to be changed, without modifying the underlying file's name. ! Mutt will look for the user's muttrc additionally in $XDG_CONFIG_HOME/mutt/. + Compressed mbox and mmdf files are now supported via open-hook, close-hook, and append-hook. See contrib/sample.muttrc-compress for suggested settings. Note this is a compile-time option: --enable-compressed. + When $flag_safe is set, flagged messages cannot be deleted. + The '@' pattern modifier can be used to limit matches to known aliases. + creates a hotkey binding to a specific message. The hotkey prefix is specified via $mark_macro_prefix. + and can be used to add/remove environment variables passed to children. ! Mutt will now use the built-in OpenSSL SSL_set_verify() callback to verify certificates. This allows better support for verifying chains, including alternative chain support. + $uncollapse_new controls whether a thread will be uncollapsed when a new message arrives. ! $to_chars and $status_chars now accept multibyte characters. + allows replacing matching subjects with something else. This can be used to declutter subject lines in the index. + can be used to add, change, or delete a message's X-Label. ! Pattern expressions with ~y support label tab completion. + The header cache now also supports Kyoto Cabinet and LMDB as backend databases. 1.7.2 (2016-12-04): ! Bug fix release. No features were modified or added. ! Fixes for OpenSSL 1.1. Versions less than 0.9.6 are no longer supported. 1.7.1 (2016-10-08): ! Bug fix release. No features were modified or added. 1.7.0 (2016-08-18): ! Improved alignment when using multi-column characters with soft-fill (%*X) and right-justified (%>X) format strings. + The COLUMNS environment variable will be set to the width of the pager when invoking display filters. This can be used in copiousoutput mailcap entries to allow their output to match the pager width. + The sidebar patch has been merged. Please watch for airborne bovine. See the documentation for all the options, or simply enable it with 'set sidebar_visible'. + $mail_check_stats and $mail_check_stats_interval control whether, and how often, to scan for unread, flagged, and total message counts when checking for new mail in mailboxes. These statistics can be displayed in the sidebar and browser. + $trash, when set, specifies the path of the folder where mails marked for deletion will be moved, instead of being irremediably purged. + The function can be used to delete an entry and bypass the trash folder. + $folder_format has new format strings %m and %n, to display total and unread message counts for mailboxes. Note that $mail_check_stats should be enabled to use these. ! When browsing IMAP, %N will now display 'N', instead of the unread message count. Please use %n to display unread messages. 1.6.2 (2016-07-06): ! Bug fix release. No features were modified or added. 1.6.1 (2016-05-01): ! Bug fix release. No features were modified or added. 1.6.0 (2016-04-04): + Enabled utf-8 mailbox support for IMAP. + New expandos %r and %R for comma separated list of To: and Cc: recipients respectively. + Improved support for internationalized email and SMTPUTF8 (RFC653[0-3]). ! $use_idn has been renamed to $idn_decode. + $idn_encode controls whether outgoing email address domains will be IDNA encoded. If your MTA supports it, unset to use utf-8 email address domains. + The S/MIME message digest algorithm is now specified using the option $smime_sign_digest_alg. Note that $smime_sign_command should be modified to include "-md %d". Please see contrib/smime.rc. + $reflow_space_quotes allows format=flowed email quotes to be displayed with spacing between them. ! multipart draft files are now supported. + The "-E" command line argument causes mutt to edit draft or include files. All changes made in mutt will be saved back out to those files. + $resume_draft_files and $resume_edited_draft_files control how mutt processes draft files. + For classic gpg mode, $pgp_decryption_okay should be set to verify multipart/encrypted are actually encrypted. Please see contrib/gpg.rc for the suggested value. ! mailto URL header parameters by default are now restricted to 'body' and 'subject'. + mailto_allow and unmailto_allow can be used to add or remove allowed mailto header parameters. ! The method of setting $hostname has been changed. Rather than scanning /etc/resolv.conf, the domain will now be determined using DNS calls. 1.5.24 (2015-08-31): + terminal status-line (TS) support, a.k.a. xterm title. see the following variables: $ts_enabled, $ts_icon_format, $ts_status_format ! $ssl_use_sslv3 is disabled by default. ! command-line arguments: -H now combines template and command-line address arguments. ! GnuPG signature name is set to signature.asc + New color object "prompt" added. + Ability to encrypt postponed messages. See $postpone_encrypt and $postpone_encrypt_as. ! History ring now has a scratch buffer. ! mail-key is implemented for GPGME. (Requires a recent GPGME). ! Removed GPG_AGENT_INFO check for GnuPG 2.1 compatibility.
