Spruce is an X11 email client written in GTK+. It is geared towards being small and fast, supporting all the common features that users want or need without sacrificing usability or functionality.

Fixes for a number of segfault-causing bugs, improved E/SMTP support (which should allow anyone with a picky SMTP/ESMTP server to send mail now), functionality for the cut/copy and paste menu items in the main and composer windows, and improved GnuPG support.
Fixes for a number of bugs that were reported in the last week to really remove attachments and not just from the clist, Solaris fixes, and a fix for the UIDL problem that spruce was having with a few POP daemons, an imap-accounts patch, a new composer window, IMAP namespaces no longer require a '/' at the end (spruce will now auto-detect if it's not there and append it for you), the IMAP namespaces no longer appear as part of the mailbox name in the mailbox tree, and changed the "Expunge" key accelerator to Control+E to avoid accidently expunging emails.
