ReactVersions.js

'use strict';

// This module is the single source of truth for versioning packages that we
// publish to npm.
//
// Packages will not be published unless they are added here.
//
// The @latest channel uses the version as-is, e.g.:
//
//   19.0.0
//
// The @canary channel appends additional information, with the scheme
// <version>-<label>-<commit_sha>, e.g.:
//
//   19.0.0-canary-a1c2d3e4
//
// The @experimental channel doesn't include a version, only a date and a sha, e.g.:
//
//   0.0.0-experimental-241c4467e-20200129

const ReactVersion = '19.0.0';

// The label used by the @canary channel. Represents the upcoming release's
// stability. Most of the time, this will be "canary", but we may temporarily
// choose to change it to "alpha", "beta", "rc", etc.
//
// It only affects the label used in the version string. To customize the
// npm dist tags used during publish, refer to .github/workflows/runtime_prereleases_*.yml.
const canaryChannelLabel = 'rc';

// If the canaryChannelLabel is "rc", the build pipeline will use this to build
// an RC version of the packages.
