Add two missing changes to changelog

[Jacalz]

### Description:

I should have cough this sooner, but I noticed that there were two relatively important mentions that didn't manage to get onto the changelog. Either way, it should now be there before the full release is published on GitHub (not within the tag though).

Checklist:

• [ ] Tests included.
• [x] Lint and formatter run with no errors.
• [x] Tests all pass.
