## Timeline of updates

- **resolved** 2021-10-13 04:10 UTC: Earlier today we released JavaScript SDK 2.19.3. When we realized the release was broken, we deprecated the release and took it down. For a few hours, the unpkg CDN was caching an invalid URL. After rolling forward with a 2.19.4 release, the unpkg CDN is now returning a valid JS SDK release. Note that we do not recommend depending on open-source CDNs for serving the LaunchDarkly SDK in production environments.

_From the vendor’s published history: only the final update text is available for incidents before Rewindex began polling this page._
