v1.10.0

This will probably be the last minor release of yaml@1. I'm aiming to release yaml@2 within a few months; prereleases of that will be published using the next dist-tag on npm. Patch releases for 1.10 may still happen, if necessary.

New Features

• Use Rollup for Node.js & browser builds (#165)
  • This removes most of the internal dist/ paths from the release. If you want/need to use a class or function that is no longer public, please file an issue and we can add it to the exports.
  • Drop dependency on @babel/runtime. After this, the package has 0 runtime dependencies. 🎉
  • Add exports { Alias, Collection, Merge, Node } to 'yaml/types'
• Document Schema.createPair() & make its ctx arg optional (#157)
• Always indent top-level scalars with lines starting with document markers or % directives (#162)
• Use double-space when forcing top-level block scalar indent, for clarity (#162)
• Add getNodes(): string[] method to Anchors (#166)
• Refactor Jest config, adding tests for compiled dist/ endpoints
• Rename & refactor source files. This should have no effect on the results, but lots of stuff moved around
