Save for Web has been depreciated in the latest CC version of PS. It has been replaced by a very similar export function, that allows very similar control over the output. It has a new quick option, that uses as set of saved options. This new tool is though lacking the max file size option for JPEG files that is available in SfW. At the moment SfW is still included as a legacy option, but it is only a matter of time before it vanishes.
I have to say that I don't use either of these options in PS very often anymore, since I use LR extensively, and use it as my main image viewing software on my computer. So I only have my RAW and master edit files stored locally. I just export from LR when I need a file to post etc. LR makes this really easy since you an save export presets, and of course the LR export dialogue still has the max size option.
