We've just released Movable Type 3.01D. You can download the new version by logging into your Movable Type Account and using the "download" link for the appropriate license. If you're upgrading from 3.0D, there's no need to run any upgrade script for this release: just upload the files to your server and you should be ready to go!
This release fixes a number of bugs that were present in 3.0D. The lot of it boils down to this:
In your comment preview template, change <MTCommentFields> to <MTCommentFields preview="1">. This way the comment fields will know to include your preview text.
TypeKey sign-in is now easier to integrate with your custom templates. Just use <$MTRemoteSignInLink$> as the target of the "sign in" link, and use <$MTRemoteSignOutLink$> as the target of the "sign out" link. If you're doing this on a static template page (like the individual archive), you probably want to add the static="1" argument, so that commenters will land on the same page after they've signed in.
Once you've done that, add this line to your mt.cfg:
TypeKeyVersion 1.1This adds additional security, but it won't work unless you're using MTRemoteSignInLink.
As always, let us know if you have any problems! Enjoy.
