New Release: SDK v5

The latest version of the Lit SDK, v5, has just been released. Included are several improvements, feature additions, and breaking changes all aimed at enhancing the overall performance of the Lit SDK. 

Here's everything you need to know about the latest changes and additions:

🚨 Breaking Changes & Important Updates

• Removes ipfs-http-client: resolves build issues when running in nextjs
• Now using cross-fetch instead of directly injecting node-fetch as a polyfill solution for fetch (commit)
• Changes getLatestBlockhash() on the LitNodeClient to be an async method. This was previously a synchronous call (commit)

🛠️ Enhancements and Fixes

• Fix to global polyfill of Buffer causing errors (commit)
• Addition of static eth wallet auth method in lit auth client (commit)
• Fix to ILitNodeClient interface compatibility (commit)

The v5 SDK is now the default for developers building on Lit.
