@kazupon
I created a v8 branch which diverts from main at 7930a27, I have also cherry picked some changes from the main branch where possible.

If this PR gets merged it will need to be added to the v8 branch as well, will the normal release flow work from that branch? 🤔

📝 Checklist

• I have linked an issue or discussion.
• I have added tests (if possible).
• I have updated the documentation accordingly.

Thank you!
The release flow using GitHub Actions is difficult, so we need to release manually.
