Are any of your mods compatible with 2.1 yet? I'm in the early planning stages of a new website and I can definitely see a use for a couple of them - specifically auto media embedder and social logins

Those two are, just like most of my mods, in each mod page you can see at the top a banner to see if it's compatible

Any ETA on the 2.1 RC2+ version of Shoutbox?

The current products working with 2.1 RC1 are already compatible with 2.1 RC2!
