3.13.011 Oct 2015 20:50 minor feature: Preferences are now saved to disk immediately on pressing OK or Apply. New preferences have been added for default sorting of the message lists. They are found in the 'Message list' frame of the Display/ Summaries page of the general preferences. These options only apply to newly created folders. The menu item 'Delete thread' has been moved to the Message menu. Previously clicking it would not delete the thread, but just move it to the Trash folder. Now it will delete the thread. An additional menu item has been added, 'Move thread to trash', which implements the original behaviour. Compose window: By default it is no longer possible to add user- defined headers, with only those pre-defined in the drop down menus being possible. To restore the old behaviour, a new hidden preference has been added: 'type_any_header', setting this to 1 restores the old behaviour. Automatic account selection is now also applied when you reply to one of your own messages, e.g. from the Sent folder. Folder list: The Left and Right cursor keys now collapse or expand the currently selected folder tree item. The Left cursor key also moves the selection to parent folder, if current folder is within a collapsed tree. Folder list: The Home and End keys now move the selection to the first folder and last folder in the tree. Account Auto-configuration: when errors occur, a more detailed error message is shown. GnuPG plugins: An option has been added to specify the location of the GnuPG executable. GnuPG plugins: A new hidden preference has been added which limits the number of results returned when using your keyring for address auto-completion: 'autocompletion_limit'. The default value is 0, which means there is no limit, any other number will limit the results to that number. Python plugin: Folder has been added to MessageInfo objects. The GeoLocation plugin is no longer included. The user manual has been updated. The man page has been updated. Updated translations: Brazilian Portuguese, Briti
3.12.021 Jul 2015 05:25 minor feature: New plugin: ManageSieve. Manage sieve filters on a server using the ManageSieve protocol. Filtering/Processing: increase range for age matcher condition. Filtering/Processing: 'mark_as_spam' now only marks as spam, it does not do an additional move. Compose window: From line gets its own label with mnemonic. Compose window: more intuitive right-click behaviour in attachments list. QuickSearch: 'Cc' added to the mixed search: From/To/Cc/Subject/Tag. Folder list: Added 'Mark all read recursively' to context menu. Support for Mac-cyrillic encoding. IMAP: Support for SCRAM-SHA-1 authentication mechanism. PGP plugins: Display validity of signatures.

3.11.128 Oct 2014 03:15 minor feature: Use 'gnutls_priority' hidden account preference for POP3 and STARTTLS connections, in addition to SMTP.

3.11.022 Oct 2014 03:18 minor feature: SSLv3 server connections are now disabled by default, in response to the POODLE vulnerability, see https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3566. Several PGP/Core plugin improvements Indicate when a key has been revoked or has expired when displaying signature status. For example, "Good signature from s, but the key has expired." "Good signature from s, but the key has been revoked." When displaying the full information, show the Validity, and the Owner Trust level. Also indicate expired and revoked keys, and revoked UIDs. The "Content-Disposition: attachment" flag in PGP/MIME signed messages has been removed. It was confusing for cetain MUAs. A new version of the RSSyl plugin, completely redesigned and rewritten. Migration from the previous version is automatic, it has a new storage format in /.claws-mail/RSSyl/ (hierarchical directories instead of flat file format). It uses the expat library instead of libxml2 for parsing feed data. The results of TAB address completion in the Compose window have improved ordering. Order of results: 1. Match beginning of name 2. Match beginning of additional names 3. Match complete email address before @ 4. Match beginning of email address 5. Compare relative position of match 6. Compare name alphabetically 7. Compare address alphabetically.* Due to popular demand, use of the Up key in the message body in the Compose window stops at the top of the message body and does not continue up to the header fields. This reverts the behaviour introduced in version 3.10.0. In the Compose window, when navigating with the arrow keys, selecting, and thus modifying, the Account selector is now prevented. In the Compose window, a mnemonic (s) has been added to the Subject line. The Queue folder is highlighted if there are messages in its sub- folders and the tree is collapsed. When sorting messages by 'thread date', clicking the 'Date' column header will now toggle between ascending/descending and will not switch to 'date' sorti

Quick search focus was fixed, and PGP keys use RSA 2048 per default. The .desktop shortcut now contains Compose and Receive actions. Various localizations were updated.
