Where to download the beta?

You can download the beta for MultiMarkdown Composer v5 here.

(Unfortunately there was an issue with the Sparkle signing key, so you will have to download this version – it cannot be directly updated from the prior version within the app….  My apologies.)

I'll try to keep this link updated, but if you get a warning about the beta being expired, just be sure to choose the "Check for Updates" menu item.  You *should* be able to update even if the beta is otherwise expired.
