New in Claws Mail 3.14.1 (Nov 7, 2016)

  • New in this release:
  • hide_timezone', a new hidden preference that sets the timezone of date fields sent over the network to the unknown timezone value as specified in RFC 5322 §3.3. Default value is false (i.e., send available timezone information).
  • rewrite_first_from', a new hidden preference which works around a limitation of some servers with 'overly-liberal parsers'. When this is turned on and the Content-Transfer-Encoding is set to 8bit or 7bit, in a message body starting with 'From ' the 'From ' will become '=46rom ' (i,e, encoded form of 'F') and the Content-
  • Transfer-Encoding will be changed to Quoted-Printable. When it is turned off no such modification will be made but it is very likely that an MTA will convert the 'From ' to '>From '. See RFC 4155 for further details. Default value is '1', turned on.
  • Templates: it is now possible to attach a file, using attach_output{sub_expr}' or '|A{sub_expr}', 'sub_expr' is evaluated as a command-line to get the filename name from, using an absolute /path/to/filename.
  • IMAP mailboxes which show subscribed folders only are now indicated by a green folder icon.
  • The Icon Legend has had the missing folder icons added and also has an improved layout.
  • Drafted messages: Do not add Message-ID for draft, unless the message already has one. A Message-ID header is now only added when queuing a message, and any existing Message-ID and References headers in drafts, if there are any, are kept.
  • Disable hiding threads and messages in draft folders.
  • The /View/Go to/... actions now respect the 'Open message when selected' option.
  • In the UI 'POP' is used instead of 'POP3', 'IMAP' instead of IMAP4', 'SSL/TLS' instead of 'SSL'.
  • GnuTLS: Enforce "strong enough" Diffie-Hellman prime even when using older versions of GnuTLS library.
  • Since GnuTLS 3.1.7, this minimum size is dictated by the priority string, and currently (GnuTLS 3.3.0) the "safe-enough" value is 1008 bits. We set this minimum size explicitly for older GnuTLS versions.
  • Users who are affected by this (their servers use DH prime smaller than 1008 bits) can override this by using a priority string starting with the keyword "LEGACY". However, this keyword only works with GnuTLS 3.3.0 or newer.
  • RSSyl plugin: Enable keeping old items by default.
  • vCalendar plugin: The ics file name is now used for the WebCal subscription folder name.
  • vCalendar plugin: Use hours/minutes for vcalendar alert time.

  • New in this release:
  • hide_timezone', a new hidden preference that sets the timezone of date fields sent over the network tthe unknown timezone value as specified in RFC 5322 §3.3. Default value is false (i.e., send available timezone information).
  • rewrite_first_from', a new hidden preference which works around a limitation of some servers with 'overly-liberal parsers'. When this is turned on and the Content-Transfer-Encoding is set t8bit or 7bit, in a message body starting with 'From ' the 'From ' will become '=46rom ' (i,e, encoded form of 'F') and the Content-
  • Transfer-Encoding will be changed tQuoted-Printable. When it is turned off nsuch modification will be made but it is very likely that an MTA will convert the 'From ' t'>From '. See RFC 4155 for further details. Default value is '1', turned on.
  • Templates: it is now possible tattach a file, using attach_output{sub_expr}' or '|A{sub_expr}', 'sub_expr' is evaluated as a command-line tget the filename name from, using an absolute /path/to/filename.

  • The Icon Legend has had the missing folder icons added and alshas an improved layout.
  • Drafted messages: Dnot add Message-ID for draft, unless the message already has one. A Message-ID header is now only added when queuing a message, and any existing Message-ID and References headers in drafts, if there are any, are kept.
  • Disable hiding threads and messages in draft folders.
  • The /View/Gto/... actions now respect the 'Open message when selected' option.
  • In the UI 'POP' is used instead of 'POP3', 'IMAP' instead of IMAP4', 'SSL/TLS' instead of 'SSL'.
  • GnuTLS: Enforce "strong enough" Diffie-Hellman prime even when using older versions of GnuTLS library.
  • Since GnuTLS 3.1.7, this minimum size is dictated by the priority string, and currently (GnuTLS 3.3.0) the "safe-enough" value is 1008 bits. We set this minimum size explicitly for older GnuTLS versions.
  • Users whare affected by this (their servers use DH prime smaller than 1008 bits) can override this by using a priority string starting with the keyword "LEGACY". However, this keyword only works with GnuTLS 3.3.0 or newer.
