• Chore

Some questions and please check the CI as yarn install is failing.

1. Why do we still need to initialize the events? Cant we fire them directly after this upgrade?
2. Did you check if we need to upgrade @sitecore/components, sitecore/byoc, @sitecore-feaas/clientside dependency and make any relevant changes?
3. This would be a breaking change right?

Please update the upgrade guide and changelog.

@addy-pathania Good questions.

Why do we still need to initialize the events? Cant we fire them directly after this upgrade?

We cannot, initialization is still required.

Did you check if we need to upgrade @sitecore/components, sitecore/byoc, @sitecore-feaas/clientside dependency and make any relevant changes?

If we remove context logic - yes. I decided not to do that - not only @sitecore/components but FEAAS depends on it as well and it will require a good bit of refactoring. With seeming rush get the update done, I think the simpler appoach is best.

This would be a breaking change right?

Yeah you're right, since it will need an extra dependency. I'll put this in upgrade guide.

Looks great! see just one comment.
Also - don't we need to have upgrade entry for CDPPageView component?
