Release v1.0.0

Zerokit v1.0.0 has arrived!

This isn’t just a version bump; this is a major milestone for the project. We’ve spent a lot of time under the hood cleaning up the architecture, unifying how our types work, and making sure the library is rock-solid for production.

Here is the lowdown on what we’ve been working on.

The Great Refactor (API & Types)

The biggest change in v1.0.0 is a massive unification effort. Previously, our FFI, WASM, and Rust APIs sometimes felt like distant cousins. We’ve brought them all under one roof.

• Unified RLN Types: We aligned the types across the board. Whether you are using Rust, WASM, or FFI, the data structures and serialization logic now behave consistently.
• Cleaner APIs: We refactored the public interfaces to make them more intuitive and simplified how we handle errors.
• Documentation: We’ve updated the docs and examples to match this new reality, so getting started should be much smoother.

WebAssembly Improvements

For those of you running Zerokit in the browser:

• No more Buffers: We reworked the rln-wasm modules to move away from buffer-based serialization in favor of a cleaner approach.
• Parallel Package: We split out the parallel WASM package, giving you more flexibility in how you bundle and deploy for the web.

Other Improvements

• Memory Leak Fix: We found a tricky memory leak in calc_witness that could cause issues over long-running processes. We patched the leak and improved the pattern for how we handle memory deallocation in the FFI. It’s much tighter now.
• Nix Love: We bumped nixpkgs and added a binary cache, so if you're using Nix, your builds should be snappier.
