⚡️ 0.32 RELEASE 🚀

libp2p uses the new multiformats line and ships a smaller bundle

🔦 Highlights

🆕 Multiformats update

We updated to the new multiformats stack, removing older multiformats modules that are no longer maintained. This is a library defining common interfaces and low level building blocks for various interrelated multiformat technologies (multicodec, multihash, multibase, and CID). They can be used to implement custom base encoders / decoders / codecs, codec encoders /decoders and multihash hashers that comply to the interface that layers above assume.

Thanks to @achingbrain for PRing all the libp2p modules ❤️

🔒 libp2p-noise updated

The new version of libp2p-noise is now faster and results in smaller bundles for applications built on top of libp2p. In short, bcrypto was replaced was by some of the goodies stablelib provides in an isolated fashion.

• ~27% decrease on its bundle size, from 191.5kb to 141.2kb (minified+gzipped), which represents a full bundle size decrease by ~10% in js-ipfs

• ~46% speed improvement

NEW:
handshake x 39.97 ops/sec ±4.98% (67 runs sampled)
Done in 6.04s.

OLD:
handshake x 27.23 ops/sec ±4.57% (67 runs sampled)
Done in 6.10s.

Thanks to @mpetrun5 and @mpetrunic ❤️
