[NTG-context] Does ConTeXt still support ePub output?

I recently learned I need to produce an ePub copy of my document, which will be used to produce braille and other versions of my file for people with limited or no vision. As I understand this is just like a ZIP file containing a bunch of HTML files with some links to each other. Though I could manually go and create tons of HTML files for it, I notice the ConTeXt Garden does mention ePub output as a possibility, but this page was updated in 2014, and I don't see any of hte sample code working. Is ePub still a file format that ConTeXt can output? Does it require a significant rewrite of ConTeXt document code to be produced or is there a simple way to output this format? --Joel
