Release Notes: This release moves all of the improvements from the latest experimental release into the stable release. Major improvements include a newer and more robust email parser and an alternative database format for people who can't use either PBL or BDB. It includes a new email parsing algorithm that improves parsing speed and captures more meaningful terms than the old one. A new auto-train command can be used to build a more optimal starting database than using the spam/good or train-spam/train-good commands.
Release Notes: This release fixes a pair of bugs related to email messages with no lines in their bodies. Headers from email messages with no bodies were not being tokenized, and it was possible for a message with invalid MIME headers and no body to lead to a crash.
Release Notes: This release fixes a bug in decoding malformed base64 encoded data that manifested itself in some architectures. It also corrects a typo in the online help. Some code cleanup and minor performance tweaks were added as well.
Release Notes: Contains all improvements from the 1.3 experimental versions, including tokenization of image attachments to stop content-free image spam, native support for maildir mailboxes, and an online help system. Also includes significant performance improvements, and closes all open bugs from 1.2a.
Release Notes: This release restores the -o suspicious-tags feature that had been accidentally removed in 1.2. It also fixes a text attachment parsing bug introduced in 1.3x1 (text attachments were effectively parsed dozens of times).
Release Notes: This release adds support for the Maildir (qmail) mailbox format, an online help system, and two new commands: create-db and create-dir.
