Release Notes: This release adds shared/public dual database functionality. Using the -D option allows all users to share a large read-only database of common terms while storing terms with different counts in their own private databases. It also adds improved performance when scanning many small mboxes (mh directories), improved commandline argument checking, changes to file locking to use shared locks when performing read-only operations, and the use of autoconf instead of a simple Makefile.
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.
