Hi @wert2all why this change wasn't added to 2.1.8-preview? Are there any issues? Is it possible to add it to final release?

[ishakhsuvarov]

@ihor-sviziev Looks like by the time this PR was processed 2.1.8-preview was already in testing. To maintain quality we stop adding new commits after testing has started.

@ishakhsuvarov thx for clarification. Will it be added to 2.1.8 release or that means all non-merged changes will not be included?

[ishakhsuvarov]

@ihor-sviziev I can not give precise information at the moment, but most likely it will not be included. I will provide update as soon as I know for sure.
