 - __None, ideally.__ If you have an application that ran without warnings on v1.13, you should be able to update to 2.0.0 without a hitch. If this isn't the case, please [open an issue](https://github.com/rmosolgo/graphql-ruby/issues/new?template=bug_report.md&title=[2.0%20update]%20describe%20your%20problem) and let me know what happened! I plan to maintain 1.13 for a while in order to ensure a smooth transition.
 - But, many legacy code components were removed, so if there are any more references to those, there will be name errors! See #3729 for a list of removed components.
