# 0.55.0

Released on 2024-10-28.

## Upgrade Instructions

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

## Enhancements

1. Qmod/Python: Functions `assign`, `assign_amplitude`, `inplace_xor`, and
   `inplace_add` are equivalent to the operators `|=`, `*=`, `^=`, and `+=`
   respectively except that they can be used in operands (Python lambda
   functions):

[comment]: DO_NOT_TEST

```python theme={null}
within(
    lambda: assign(x, y),  # y |= x
    lambda: inplace_xor(y, z),  # z ^= y
)
```

2. Support non-equation Boolean expressions as control conditions:

    ```python theme={null}
    @qfunc
    def main(a: Output[QBit], b: Output[QBit], res: Output[QBit]) -> None:
        allocate(1, a)
        allocate(1, b)
        allocate(1, res)
        control(a & b, lambda: X(res))
    ```
  </Tab>

  <Tab title="Native">
    ```
    qfunc main(output a: qbit, output b: qbit, output res: qbit) {
      allocate(1, a);
      allocate(1, b);
      allocate(1, res);
      control (a & b) {
        X(res);
      }
    }
    ```
  </Tab>
</Tabs>

## Interface Changes

1. Parameters `value` and `target` of functions `inplace_add` and `inplace_xor`
   have been renamed to `expression` and `target_var` respectively.
   Parameters `value` and `target` will no longer be supported starting on
   02/12/24 at the earliest.

## Bug Fixes

1. Solve a within-apply bug.
