+This script has been created to automate the deployment of the CDN resources at the same time as publishing of the NPM packages. This script will publish the full release version (v2.#.#) to next and public. Release candidates are published only to next. Dev and nightly builds retain their own folders, while alpha builds remain isolated in test storage. It does NOT change the major (ai.2.min.js) or minor (ai.2.#.min.js) release versions.
+
+Supported version types are `release`, `rc`, `dev`, `nightly` and `alpha`. Unsupported versions fail validation before connecting to Azure. Beta release/channel options are no longer supported by publishing, activation or listing tools; existing CDN files are not deleted. The dated example output below is retained as historical output.
+
+Offline publishing and activation regression tests can be run from the repository root with
+`pwsh -NoProfile -File common\publish\Tests\CdnPublishing.tests.ps1`; they do not connect to Azure.
+
+Roll out these changes using freshly built release artifacts. Deployment pipelines execute the
+publish and activation scripts bundled in those artifacts; reusing an older artifact can still write to beta.

 - We then go through a deployment process of "promoting" the new version to the "Major" (`ai.3.gbl.min.js`) and "Minor" (`ai.3.x.gbl.min.js`) release URL's to upgrade everyone to the newly released version based on the schedule listed below

+The beta CDN channel is no longer supported by CDN publishing, activation or listing tools. Existing CDN files remain available for legacy consumers; npm prerelease tags and version-generation tooling are unchanged.

+### Significant Changes
+
+- CDN preview deployment now uses `next` instead of `beta` across the SDK, extensions, tools, and configuration.
+  Stable release artifacts publish to `next` and their existing production destinations; release candidates publish only to `next`.
+  Beta CDN publishing, activation, and listing options are removed, while existing CDN artifacts and production URLs remain unchanged.
+  Dev/nightly folders, alpha test-storage isolation, npm prerelease tags, and version-generation tooling are unchanged.
