> However, assuming no issues are found that require substantial time to 
> address, the WebAssembly Community Group would like to mark an initial 
> version of the standard as “done” in Q1 2017 which would then enable 
> browsers to start shipping WebAssembly without a flag. For our part, 
> in Firefox, this green light would mean shipping WebAssembly in 
> Firefox 52 (March 2017).
