Full Changelog: v3.2.0...v3.3.0

v3.2.0

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.
