Claws Mail 3.14.1 brings lots of changes, including two new hidden preferences, namely ‘hide_timezone’ and ‘rewrite_first_from’. While the first one is used for setting the timezone of date fields that are sent over the network to an unknown timezone value specified in RFC 5322 ??3.3, the second one is designed as a workaround for a limitation of various mail servers with ‘overly-liberal parsers’. Claws Mail 3.14.1 now enforces the “strong enough” Diffie-Hellman prime for systems that use older versions of the GnuTLS library. The RSSyl, vCalendar, PDF Viewer, and Notification plugins have been updated as well with various new features, such as support for Ubuntu’s Unity messaging menu to receive Claws Mail notifications, and it looks like a total of 25 bugs reported by users since version 3.14.0 were addressed.
