We're moving to a beta › latest release pipeline, where all non-hotfix changes are first released in a beta before being promoted to a stable release.

We'd love it if you'd start using the latest betas and let us know early and often if you find any bugs or regressions!

Highlights

Muir Glacier Mint 🏔️ 🍬 🌿

This release updates ganache-core's default hardfork to muirGlacier, inline with Ethereum's mainnet and testnet's. As many of you know, the Muir Glacier hardfork is a minor adjustment in the way difficulty was calculated; it was intended only to delay the 'ice age' (by 52 million seconds (~611 days)). Since ganache-core mines with 0 difficulty, users can expect functionality to remain identical to the istanbul hardfork.

Finally, this beta version contains a (potential? 😅) fix to work around an open Merkle Patricia Tree bug from 2016 ethereumjs/merkle-patricia-tree#12! If you do still get the dreaded TypeError: Cannot read property 'pop' of undefined please file an issue with all the details!
