Summary

Concrete 2.8.1 introduces a major new feature the interoperability between Concrete and TFHE-rs, combining the strengths and features of both libraries. While Concrete is optimized for fast computation on small integer DAGs, TFHE-rs supports integers of arbitrary size but with slower performance. This release provides a bridge between the two, allowing developers to benefit from both libraries' capabilities.

Additionally, Concrete modules has been improved. Previous versions of modules required complex setup of the optimal composition rules and input-sets, in Concrete 2.8.1, an automatic module tracing feature allows the compiler to automatically compute the right input-sets for each functions and compositions rules, simplifying the user experience

Summary

Concrete v2.7.0 includes several key enhancements and new features:

• GPU backend: Concrete comes for the first time with a GPU wheel! To facilitate this, we have set up a public Zama PyPI repository at https://pypi.zama.ai/. Here, you can find stable, release candidate (rc), and nightly wheels for both CPU and GPU.

• Module optimizations: FHE modules have been improved. Users can now describe the wiring between module functions, allowing for better compilation and optimization of complex programs.

• New features and fixes: As with all new Concrete releases, this version introduces several new features, including fancy indexing, dynamic assignement/indexing, overflow detection in simulation and some bug fixes.
