I find it more convenient to keep test projects together near the corresponding src projects, rather than in a separate test/ folder, at least in medium and large projects

The wait is over! Fable 5 Release Candidate is officially here.

After a year of hard work from the community, we're bringing you:
✨ .NET 10 & F# 10 support
🐍 A massive Python update (now powered by a Rust core & PyPI!)
🌐 Cleaner JS/TS Pojo bindings
