Hello Linux Geeksters. As you may know, Claws Mail is an email client and news reader, written in GTK+. It has a simple and intuitive interface, allowing the user to manage their mails easily.

The latest version available is Claws Mail 3.11, which has been recently released, coming with both new features and bug-fixes. Among others, the RSSyl plugin has been rewritten, the migration from previous versions is now done automatically, the flat file for storage has been replaced by hierarchical directories placed in ~/.claws-mail/RSSyl/, now the Up key pressed in the message body from the Compose window stops at the top of the message and does not continue up to the header fields, the POODLE vulnerability has been closed, the TAB address completion has received improvements and other bug-fixes have been implemented. For a full list of changes, see the changelog.
