No document/changelog of Scriptable Build Pipeline 1.4.1-preview

Hi, the lateset ScriptableBuildPipline packages 1.4.1-preview is available, but I found that its changelog/documentation pages return 404 error.

https://docs.unity3d.com/Packages/com.unity.scriptablebuildpipeline@1.4/index.html
https://docs.unity3d.com/Packages/com.unity.scriptablebuildpipeline@1.4/changelog/CHANGELOG.html

I want to know what is changed in this release.

Thanks.

Changelog | Package Manager UI website works just fine for me:

[1.4.1-preview] - 2019-04-16

  • Fixed “Path is empty” exception in build cache
  • Fixed an edge case where a valid cache entry could be returned for an invalid request
  • Added BuildCache.PruneCache API to trim the cache down to a limit, called in the background after a build
  • Moved BuildCache menu options and preferences to the “Edit/Prefferences…” window

It seems that simply delayed. Thanks for investigation.
