Once again, the February update will be necessary for full functionality of the Euro and Yuan spreadsheets. I am allowing a one month transition period that will allow full functionality for all spreadsheets prior and after the February 2017 update. Beginning March 1st, 2017, all spreadsheets prior to the release in February 2017 will be obsolete.
I apologize for the inconvenience and know that API's should be backwards compatible with new updates, but this change is necessary to allow the site and all spreadsheets to be offered for free. I do not want to have to end up charging users for access to a spreadsheet of their choosing. The older spreadsheets that some of you are still using is far outdated and that API is still calling prices for coins that are either abandoned or lack a large user base.
Thank you for your cooperation and continued usage.
