See [Cloud Providers](https:///user-guide/execution/cloud-providers/) section in the user guide. * The default optimization level in the synthesis preferences has been changed from `OptimizationLevel.HIGH` (3) to `OptimizationLevel.LIGHT` (1). For more information about optimization level see the [optimization level](https:///user-guide/synthesis/preferences/#optimization-level) section in the user guide. ## Fixes ## Bug Fixes * Fix a synthesis bug that causes, in some cases, the function under power to have a separate power for each function, instead of sharing it as a whole. * Fix a failure in hardware-aware synthesis of parametric models for the `Azure Quantum` provider. * Fix a bug in `get_hf_state` when using qubit tapering. ## Visualization ### Introducing "Variables View" A new compact visualization mode that displays quantum variable flow at a higher level perspective. Toggle between this streamlined view and the traditional qubit grid overlay using the Variables View switch in the visualization menu bar.” ## Classiq Studio ### Memory monitor A new memory monitoring feature that tracks and displays resource usage during Classiq Studio Usage, providing real-time insights into memory consumption patterns. plot
