2.9.3-beta.0 - Popcorn (of undefined) 🍿

 Highlights    How to Upgrade    Changelog    Related Releases 

---

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

Popcorn (of undefined) 🍿

This beta version contains a (potential? 😅) fix to work around this open Merkle Patricia Tree bug from 2016 ethereumjs/merkle-patricia-tree#12!

Being that this seems to be a race-condition bug it is difficult to say for sure if this will fix all instances of this bug. If you do still get the dreaded TypeError: Cannot read property 'pop' of undefined after upgrading to this version please file an issue with the details!

2.9.2 - Hotfix 🔥

 Highlights    How to Upgrade    Changelog    Related Releases 

---

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

The previous release, v2.9.1, changed the way chainId's (the v value) were handled for raw transactions which in turn was preventing them from being accepted in certain situations. This fixes this issue and reverts the change that enabled EIP-155 replay protection in order to preserve backwards compatibility. Additionally, the mismatch of between ganache-core's hardcoded chainId and its default net_version caused metamask signed transactions to always fail. Ganache-core will accept any v value as it used to prior to v2.9.2.

This behavior will change in the next major release of ganache-core and the default behavior will be to validate the v value of raw transactions against the configured chainId.

We just got back from TruffleCon 2019 and it was amazing. And so was the inspiration for this release: the "Three Milk Cuban Flan" I ate while visiting Washington.

This version of ganache-core adds TypeScript typings and updates transaction signatures to align with the new spec changes. We also now expose a new option: account_keys_path, which brings the cli flag of the same name from `ganache-cli into ganache-core.
