Version 2.3.1 of SpamSieve is now available.

This is a free update that includes the following changes:

• Works with Apple Mail on Mac OS X 10.4.1. SpamSieve should automatically install a new copy of its Apple Mail plug-in the first time it’s launched, but if it doesn’t you can do so by choosing Install Apple Mail Plug-In from the SpamSieve menu.
• Various accuracy improvements.
• Renamed the Apple Mail training commands to Train as Good and Train as Spam.
• Train as Spam is much faster in Apple Mail on 10.4 when there are multiple messages selected.
• If SpamSieve’s Dock icon is hidden, a new SpamSieve - Open Window command will appear in Apple Mail’s Message menu. This lets you quit SpamSieve or access its windows and settings while its menu bar is hidden.
• Worked around Apple Mail bug so that Train as Good now moves spam messages out of Mail’s Spam folder on 10.4, provided that SpamSieve had put them there.
• Reduced the maximum size of the Growl notification bubbles.
• Better at parsing malformed messages.
• The HTML parser is much faster with certain pathological spam messages that could previously drag parsing out for a minute or more.
• Worked around Entourage bug that could lead to the creation of multiple Uncertain Junk categories.
• SpamSieve no longer complains about the permissions on Apple Mail’s Bundles folder if you’re using a different mail program.
• Removed the Prune Corpus command. With auto-training being much smarter than in earlier versions, it’s almost never advisable to prune, and improper pruning severely reduces accuracy.
• The demo reminder window updates the number of days remaining if you leave SpamSieve running for days or weeks at a time.
• Fixed bug that could cause a crash when using Instant Purchase.
• Worked around crash caused by bug in 10.2.
• Updated localizations.
