@iamareebjamal please review.

[iamareebjamal]

Approved, but not merging as release has been freezed

[prateekj117]

@iamareebjamal I think we can merge this as well now.

[iamareebjamal]

Don't merge branches unless there are conflicts. Tests are run again without any reason and then we have to wait before merging

[prateekj117]

@iamareebjamal Ok will keep that in mind.
