Where's all the explanation on the versions

[Martoni]

Hello,

I'm looking for version explanation about 6.x, 5.x and 3.5, 3.6 chisel version.

Versioning wiki page doesn't explain why 3.6 is the last stable release and why version 5.x and 6.x are already released.

https://www.chisel-lang.org/docs/appendix/versioning

I'm a bit lost with all these versions.

Thanks

Fabien M
