Summary

Concrete v2.9.0 introduces several enhancements, new features, and fixes. Highlights include:

  • Python 3.12 support: This version is fully compatible with Python 3.12 for both CPU and GPU releases.
  • Improved interoperability with TFHE-rs:
    • Added support for more data types, including signed integers and tensors.
    • TFHE-rs safe serialization features are now utilized to seamlessly import and export ciphertexts.
    • Modules are now supported in the TFHE-rs interoperability bridge.
  • Backend update: Concrete v2.9.0 uses the latest version of TFHE-rs (v0.10.0) as the backend for both CPU and GPU, benefiting from all its latest performance and feature improvements.

In addition to these key updates, this release includes further enhancements, optimizations, and bug fixes, as outlined below.
