On July 18, 2023 Google Quantum AI released Cirq v1.2.0:

This Cirq release focuses on making it easier to express and do resource estimations for Fault Tolerant Quantum Algorithms with a number of high level improvements.

Notable improvements include the addition of a new sub-package (Cirq-FT) for rapid prototyping and resource estimation of fault tolerant algorithms that extends Cirq, and added support for Python 3.11. Since the latest Cirq v1.1.0 release in December 2022, these updates were made through the combined work of 32 developers from both the Cirq Development Team and the broader open-source community, 18 of which were first-time contributors.
