v0.6.5

After examining some code using Regenerator in the wild, I decided to reinstate require("regenerator").runtime.path, which specifies the full path of https://github.com/facebook/regenerator/blob/master/runtime.js in case you need to read that file in your projects.

It is also now possible to inject the runtime directly into the transformed AST by calling require("regenerator").transform(ast, { includeRuntime: true }). This is especially useful when you have multiple AST transform functions (in addition to require("regenerator").transform) that you want to compose together without reparsing/reprinting the source code.
