About SemVer docs.quantum.ibm.com/open-source/... :

🐍 Qiskit v2 is not backwards compatible with Qiskit v1. Upgrading blindly with `pip install -U qiskit` might break your code.

🦥 Qiskit v1.4 will receive bug fixes until Sept 2025. Use it as a transitional version `pip install -U qiskit>=1.4,<2`
April 1, 2025 at 11:10 AM
Still want something installable and runnable? I got you:

> pip install qiskit==2.0.0rc2

Grab the release candidate today! 🚀

Qiskit does not do it *that* differently. The last stage of the compilation is scheduling and it's similar to your circuit-to-pulse compiler.
