This pull request does not have a backport label. Could you fix it @donoghuc? 🙏
To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

• backport-8./d is the label to automatically backport to the 8./d branch. /d is the digit.
• If no backport is necessary, please add the backport-skip label

@mashhurs Does this need to be 9.1.0 or 9.2.0?

[mashhurs]

9.2.0 will be the correct one as 9.1 branch will have VERSION with 9.1.x.
And FYI, we do not release plugin with main branch.

Thank you

[donoghuc]

Thanks, yeah i was thinking this would just be helpful once we cut a 9.2 branch and disambiguate it from 9.0 and 9.1
