v8 Release Plan

[mydea]

This issue collects concrete things we know we want to include/do in v8 for sure. We have a lot of things captured already in various places, but not all of these things will necessarily happen in v8. The goal of this issue is to have a proper overview.

For feedback please reach out via GH discussions.

[m1heng]

Will the team try to reduce the bundle size in v8?

[Lms24]

@m1heng by removing deprecated parts of the SDK, we'll be able to reduce some size. Maybe also by the proposed hub/scope changes. However, at this time, we haven't planned a big bundle size reduction intiative as in v7.
We recently reduced Session Replay bundle size by a lot. Also, you might want to look into advanced tree shaking configuration for saving a few extra bytes.

Task list to remove internal usage of deprecated APIs: #10100
