# 1.6.0

Released on 2026-03-08.

## Upgrade Instructions

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

## Bug Fixes

* Fix an incorrect compilation when an arithmetic operation appears
  inside a `repeat` statement and the left-hand side uses the repeat
  index as a subscript.
* Change default vendor from Azure to Classiq

## Enhancements

* Added `use_double_precision` to `ClassiqBackendPreferences` to control numerical precision on Nvidia and Braket Nvidia simulators. Default is `False` (single precision). Set `use_double_precision=True` for double precision. See [Classiq backends](/user-guide/execution/cloud-providers/classiq-backends/#nvidia-simulator-usage) for details.

* Removed `max_depth` and `max_gate_count` from `Constraints`. These fields were deprecated since 0.52 and are no longer supported.
