Version History

How specification changes are recorded; the change log begins at the first 1.0 release.

This page records notable changes to the specification, newest first, once versioned releases begin. Implementations (such as io-js2) version independently under their own SemVer and declare which specification version they conform to.

1.0 Draft — in progress

The specification is in its 1.0 Draft: it is still being authored, most features are at Candidate maturity, and it may change without a version bump until 1.0 is finalized.

There are no released versions yet — the first entry here will be 1.0, recorded when the draft is finalized. Until then:

for the current maturity of each feature, see Feature Status;
for how versions and stability work, see the Versioning Policy;
for planned direction, see the Roadmap.
