MoinMoin 1.8.7 is a security bug fix release. Please update as soon as possible. See http://moinmo.in/MoinMoinDownload for the release archive and the change log. BTW, we still need much more people helping with cleaning up on master19.moinmo.in. So, especially if you speak some non-english language, you can help! See http://moinmo.in/MoinDev/Translation for details.
