The right-click mailbox menu is back, Danish NLS support has been added, lots of segfault fixes have been applied, a number of memory leaks have been plugged, the filters editor has been remade, and a few other fixes have been made.
Security and segfault fixes (will not dump core no matter what), general code cleanup, decreased lockup while downloading, new resizable panes, IMAP and improved local mail spool support, and new status windows for downloading mail.
Fixed some segfault causing bugs, added mbox support, added more language support, added more stuff to the configure script, added another filter option (All recipients) that checks both To: and CC: header fields, you can now choose to view partial headers in the preview pane, made sure that *.mbx files stay mode 0600, a few minor code cleanups, and added some #undef's to stop those annoying MIN/MAX redefinition compiler warnings.
