Upgrade Instructions

Python version 3.9 will no longer be supported starting on 2025-10-01 at the earliest.

The new qasm_to_qmod function de-compiles QASM 2 or 3 into Python/Native Qmod source code.
Added methods for execution budget management.
Cline AI agent is now installed in Classiq Studio, providing seamless AI-powered quantum development. See the AI documentation for setup instructions.
Remove negligibly small amplitudes from state vectors when the auxiliary (non-output) qubits are non-zero. These amplitudes are caused by numeric error during simulation, but they result in multiple states with the same assignment for the variables, which caused confusion.
Added several Quantum Signal Processing (QSP) related functions to the SDK: qsvt_phases for obtaining QSVT phases, qsp_approximate for approximating QSP-compatible Chebyshev polynomials, gqsp_phases for calculating Generalized-QSP (GQSP) phases, and a quantum gqsp function that implements GQSP. To use these functions the user should pip install classiq[qsp]. The existing QSVT examples and a new GQSP example will be updated in the library towards the next version release.

Fix a bug where the visualization generated unnecessary variable splits and assigned incorrect variable names in certain cases.
Support classical functions in the cost expression of minimize.
Prevent invisible blocks from being collapsed.
Adjust CZ gate boundaries to align with disconnected variable lines.
Fix Studio loading stuck until page reload.
