AssemblyScript Migration Guide

Up until now, subgraphs have been using one of the first versions of AssemblyScript (v0.6). Finally we've added support for the newest one available (v0.19.10)! 🎉

That will enable subgraph developers to use newer features of the AS language and standard library.

This guide is applicable for anyone using graph-cli/graph-ts below version 0.22.0. If you're already at a higher than (or equal) version to that, you've already been using version 0.19.10 of AssemblyScript 🙂

Note: As of 0.24.0, graph-node can support both versions, depending on the apiVersion specified in the subgraph manifest.
