Re: [january-dev] January version 2.0 release

[<Peter.Chang@xxxxxxxxxxxxx>]

Hi Scott,

The version leap is due to my changing the API in a non-compatible way. Hope to do less of this in the future.

Regards,
 Peter

Thanks Peter and all.

FWIW, I'm happy to see getMetadata deprecated...and thanks for the threadsafe work (#71) as well.

BTW...one question:   It was a pretty fast move from 1.0->2.0 for 
January...I know it's difficult to predict, but do you expect that will slow down for future releases?  i.e. stay at 2.0 for a 'while'?

Scott
