Highlights   Fixes   Miscellaneous   Changelog   Known Issues   Future Plans 

With the end of September we mark the successful joining of the original execution layer of Ethereum with its new Proof-Of-Stake consensus layer, the Beacon Chain, better known as The Merge. Congratulations to everyone who contributed to Ethereum's transition from Proof-of-Work to Proof-of-Stake.

To our users interested in trying post-merge features check out Ganache v7.4.4-alpha.0.

A special thank you to our external contributor @eltociear and contributor @jeffsmale90 for their contributions to this release.

If you have some time, we encourage you to browse our issues to find anything you'd like implemented/fixed sooner. Give them a +1 and we'll use this community feedback to help prioritize what we work on! Or better yet, open a new issue, open a PR to fix an existing issue, or apply to join our team (we're hiring!) if you really want to get involved.

We've changed 8 files across 3 merged pull requests, tallying 119 additions and 49 deletions, since our last release.

This release removes zero-config forking support for deprecated testnets: Kovan, Rinkeby, and Ropsten test networks in anticipation of Infura deprecating these testnets from the Infura API on October 5th, 2022. Infura recommends users migrate to Goerli to test deployments.

fix: calling evm_mine with a timestamp argument should reflect the change of time in subsequent blocks (#3531)

Previously, calling evm_mine with a timestamp argument would result in a block with the specified timestamp, but subsequent blocks would have a timestamp that didn't reflect this change in time. This only occurred when miner.timestampIncrement is unspecified or clock.

const provider = ganache.provider();

await provider.request({ method: "evm_mine", params: ["0x1"] });
const { timestamp: firstTimestamp } = await provider.request({
  method: "eth_getBlockByNumber",
  params: ["latest", false],
});

// wait 1 second before mining the second block
await new Promise((resolve, reject) => setTimeout(resolve, 1000));

await provider.request({ method: "evm_mine", params: [] });
const { timestamp: secondTimestamp } = await provider.request({
  method: "eth_getBlockByNumber",
  params: ["latest", false],
});

console.log({
  firstTimestamp,
  secondTimestamp,
});

Will output something like:

{ firstTimestamp: '0x1', secondTimestamp: '0x5e0be0ff' }

Where secondTimestamp is the current time in seconds, but should be 0x2.

With this change, blocks mined after providing a timestamp parameter to evm_mine, will have timestamps that reflect the change in time.
