Overview

This release focuses on quality of life improvements across the bindings. Notably:
- The blst library is now built with the portable flag (which will automatically use optimized code paths), ensuring optimal performance on supportive platforms and stability on others.
- Rust projects can now link two copies of `c-kzg-4844`, allowing for runtime switching between mainnet and minimal configurations.

Overview

This release fixes some minor issues and makes loading the trusted setup significantly faster.

⚠️ **Important** ⚠️

The trusted setup has changed; G1 points must now be in Lagrange form.

* For those using [`trusted_setup.txt`](https://github.com/ethereum/c-kzg-4844/blob/6d21a0ea981b5e1862c7a4603cf22565c8492f9a/src/trusted_setup.txt) from this repository, replace it with the latest version.
* For those using [`testing_trusted_setups.json`](https://github.com/ethereum/consensus-specs/blob/f7352d18cfb91c58b1addb4ea509aedd6e32165c/presets/mainnet/trusted_setups/testing_trusted_setups.json) from the consensus-specs, replace `setup_G1` with `setup_G1_lagrange`.
