What's the current status of the oauth2 work

I noticed there has been some recent activity, but my current working balsa is compiled from a local branch derived from oauth2-support. As I remember, the last time I compiled I went through some contortions to be sure I had all updated from master. So - I suppose my main question is whether/when oauth2-support will get merged into master. The oauth2 stuff has been working fine for me, with the only exceptions being when the email provider has been acting up (think yahoo…..) but maybe that’s not really oauth2 related anyway.
