CHANGELOG.md shouldn't include pre-release changes?

I was looking for v8.1.0 changelog, and realized that I need to read all pre-release versions in order to know what’s changed. See the changes on changelog.md:

8.1.0 (2019-07-02)

Bug Fixes

• core: handle undefined meta in injectArgs (#31333) (80ccd6c), closes CLI #14888
• service-worker: cache opaque responses in data groups with freshness strategy (#30977) (b0c3453), closes #30968
• service-worker: cache opaque responses when requests exceeds timeout threshold (#30977) (a9038ef)

Reading the other releases, there was many, many other changes on this release that are not on changelog of the version itself, but on .rc*, .next-*…

Shouldn’t the changelog be a merge of all pre-release versions?

Since opening this issue the changelog is now being updated to combine all changes since next/rc releases when the final release is made, so I’m closing this as addressed.
