This update has been in the works for the last year and a half. Its prerelease versions have been thoroughly tested by a wide number of users, and I think it's finally ready for "actual" release, for use in the mythical "production".
The breaking changes introduced here are mostly originating from the v1 CST parser having become a rather difficult beast to work with. So it's here rewritten pretty much completely, now with a lexer as a first stage. Along the way, the whole project was rewritten in TypeScript and the export paths and options refactored pretty deeply.
If you've been using the library just via its parse(), parseDocument() and stringify() functions, then it's quite likely that none of the changes affect your experience in any way. However, if you've been doing something more involved, then I would strongly recommend that you review the library's documentation site for the v2 docs.
Going forward, it's finally time to start experimenting with new YAML spec features that may eventually be included in YAML 1.3 and later. Those will be made available by specifying the version: 'next' option. However, beware! Any features available this way may be removed or have their API broken by any minor release of this library, and no compatibility guarantees with other libraries are given. In general, semver compatibility is guaranteed for features that are explicitly included in the documentation; everything else should be considered as internal implementation details.
The following is an overview of the breaking changes and new features introduced in each of the prerelease steps leading up to this release; the individual releases' notes and the PRs will contain more detail, along with specific migration guides.
