  There will be a breaking SDK upgrade in the coming months. This upgrade will make the SDK a lot easier to build with.

This upgrade will affect the interface of the SDK dramatically, and will be coupled with a protocol change - stay tuned for information on early access to the new protocol testnet.

It will also be coupled with the documentation of the SDK on [crates.io](https://crates.io/).
