v0.4.0

This second release of Curvesim is a foundational release, bringing it much closer to being a general framework for arbitrage simulations on Curve pools.

Highlights include:

• User-definable metric objects that can be used to generate custom simulation results
• Much more powerful data visualization through integration with the Altair library
• Easy instantiation of 2-token cryptopools from chain data as can currently be done with stableswap pools

A detailed list of changes and enhancements are available in the changelog.

In the coming weeks, we will be rolling out additional updates to the documentation, such as Jupyter notebooks to make it even easier for users to dip their toes into the water with Curvesim.

We're very excited by what is coming down the road:

• wrapping up cryptopool simulation capability
• incorporating more general data sources
• expanding the set of arbitrage strategies

Stay tuned and continue using Curvesim and letting us know how we can improve it!
