Release mismatches

[oyvindwe]

Thank you very much for releasing the NodeJS runtime fix!

However, there are some mismatches in the releases:

• Release v0.8.0 points to tag v0.7.2 - should either rename release or add tag v0.8.0
• Link for full changelog from release v0.9.0 note is broken (uses the non-existing tag v0.8.0)
• Tag v0 points to same commit as tag v0.7.2 - should point to same as v0.9.0
