Bare Bones Software has released version 1.4 of Yojimbo, their "effortless information organizer" that is oh so popular with the kids these days. To summarize the press release, the main new addition is long-requested "extensive" support for automation via AppleScript and Perl. Also in this release is a new "Untagged Items" factory smart collection to go along with the still somewhat new tagging feature they released with v1.3.
Of course, plenty of bug fixes and refinements also made it into this release, all of which you can view in the release notes. You can snag the new version from Bare Bones' updates page.
