In cryptoworld, most of the projects depend on some kind of public API. Whether it is Cryptocompare or Coinmarketcap APIs (btw, thanks guys!). It's always good to keep up with updates from those providers so your app won't run out of data juice by hitting a non existing endpoint.
Earlier this month I was browsing Coinmarketcap API docs by accident and I noticed whey have new V2 API. What's even more important is, that at the end of November, they'll be shutting down V1, so if you are using CMC API, don't forget to upgrade.
Public API Version 1 will be taken offline on November 30th, 2018. Please modify your application to use Version 2 prior to shutdown.
