ICICLE v3.6.0

Introducing a METAL backend!
At this release the backend is operable with cpp and Rust frontends.
Usage: same as CUDA backend, download, extract and set ICICLE_BACKEND_INSTALL_DIR env var
This version also add support for user-defined program to use with sumcheck, faster cpu sumcheck and infrastructure for integer rings

Known Issues

Metal backend is missing API implementations for Poseidon and Poseidon2 hashes, Merkle tree, Sumcheck and G2 montgomery conversions
Batch msm is only supported in shared-bases mode (where all msms reuse the same bases).

Maximize CPU Performance with Clang

For optimal performance of ICICLE on the CPU backend, we recommend building ICICLE using Clang.
• Why Clang? It provides better performance optimizations compared to other compilers.
• Automatic Detection: Simply ensure Clang is installed on your system. ICICLE will automatically detect and use it during the build process.

No additional configuration is required—just install Clang, and you’re ready to go!

Important Notice for Upgraders

If you are upgrading from a previous version:
Ensure that you update both the frontend and backend Icicle libraries. Failing to update both can result in missing symbols and unexpected crashes due to incompatibilities between versions.

Typical Installation Paths:

• Backend Libraries: Usually installed in /opt/icicle.
• Frontend Libraries: Typically located in /usr/local/lib or a similar system directory based on your setup.

Upgrade Instructions:

1. Uninstall the previous version completely to avoid any residual files.
2. Install the new version of both frontend and backend libraries.

Updating both components ensures compatibility and stability across all Icicle features in the latest release.

@yshekel

This version introduces a completely new design for ICICLE. We've developed a front-end user API that is backend-agnostic, supporting various hardware configurations. Additionally, we've added CPU support for MSM and NTT, with the CPU backend now set as the default. This allows developers to compile and run ICICLE seamlessly on Apple Mac and Linux machines as well.
