Do we used "updated" or "update"? (it's inconsistent in this PR).

Reviewed it once more time. I think I have made in consistent within particular CHANGELOG.md file.

If you want to make in consistent across repository it deserves a separate task/PR. We have some level of incossitenty.

Merging as is, there is a request for release one package. It will be good to release it with 1.8.1 SDK.
