# 0.97.0

Released on 2025-11-03.

## Upgrade Instructions

* [Python SDK](/getting-started/registration_installations#platform-version-updates)
* The IDE upgrades automatically.

## Enhancements

* Qmod now supports **automatic uncomputation** of local variables and enforces
  rules that guarantee their correct uncomputation. Similar rules are enforced
  on variables initialized inside a *within-apply* statement.

  For more details, see [Uncomputation](../qmod-reference/language-reference/uncomputation).

  Currently, violations of uncomputation rules are issued as warnings for backward compatibility.
  These will become compilation errors no earlier than 2025-12-03.

* Add the `assign_amplitude_table` and `assign_amplitude_poly_sin`
  open-library functions, to replace the `*=` operator and the
  `assign_amplitude` function.

* Add [`unscheduled_suzuki_trotter`](../sdk-reference/qmod/functions/core_library/exponentiation/#classiq.qmod.builtins.functions.exponentiation.unscheduled_suzuki_trotter),
  a variant of `multi_suzuki_trotter` that doesn't re-order the Pauli terms.

* Improve synthesis of controlled phase with theta=pi.

* This release includes initial support of classical local variables,
  assignment of mid-circuit measurements, and runtime if statements.
  Currently, only variables of type QBit can be measured, and only the
  classical bool type is supported for local variable declaration and
  assignment. This enables simple algorithms such as the quantum teleportation
  protocol. These constructs have the corresponding dedicated graphics in the
  quantum program visualization. See more details under [Classical variables](/qmod-reference/language-reference/classical-variables))
  and [Mid-circuit measurement](../qmod-reference/language-reference/mid-circuit-measurement).

## Interface Changes

* The `*=` operator and the `assign_amplitude` function are deprecated and
  will no longer be supported starting on 2025-12-03 at the earliest. Use
  `assign_amplitude_table` instead.
* Function `qdrift` now receives a sparse Hamiltonian ([`SparsePauliOp`](../sdk-reference/qmod/classical-types/#classiq.qmod.builtins.structs.SparsePauliOp))
  instead of a list of non-sparse Pauli terms (`CArray[PauliTerm]`).
  Non-sparse pauli terms in `qdrift` will no longer be supported starting on
  2025-12-03 at the earliest.

## Bug Fixes

* Fix `multi_suzuki_trotter` synthesis with symbolic evolution coefficients
  raising an internal error.
* Fix a bug where an internal error is raised when synthesizing with a maximum width constraint
  a model that contains control on a function, or a statement block, that allocates and frees qubits.

## Security

* Internal dependencies have been upgraded to address security vulnerabilities.
