Back from Devcon and our ConsenSys retreat for another release!

Thank you to our contributors @omahs, @MicaiahReid, @tenthirtyone, and @jeffsmale90 for your contributions to this release. We'd also like to thank issue contributors @gnidan, @mxork, @leroldary, @Inphi, @domalaq, @ChristianCoenen, @drortirosh, @seaona, @krzkaczor, and @aashborn.

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 32 files across 9 merged pull requests, tallying 1641 additions and 432 deletions, since our last release.

This release brings you the long-awaited eth_feeHistory RPC endpoint. Check out the Infura docs on this method if you aren't already up to speed. Give it a try and let us know if you aren't fully gruntled with the feature or if you find any issues with its performance or implementation.

It also brings a few bug fixes, docs updates, and some internal improvements.

feat: add eth_feeHistory JSON-RPC endpoint (#3351)

Adds eth_feeHistory to the JSON-RPC API. This endpoint returns gas used, baseFeePerGas, and effective reward by array of percentages accounting for gas used for a range of blocks.

Check out the Infura docs on this method if you aren't already up to speed.

Fixes: #1470

• fix: add an upper limit to # of accounts that can be generated by ganache (#3361)
• fix: add " " after the HTTP/1.1 Response Status-Code (#3404)

fix: add an upper limit to # of accounts that can be generated by ganache (#3361)

This change logs a warning to the user that performance may be impacted if more than 100,000 accounts are created.

Fixes #736

fix: add " " after the HTTP/1.1 Response Status-Code (#3404)

This change brings Ganache into strict compliance with the HTTP/1.1 Status-Line specification. Nearly all established HTTP/1.1 response parsers handle HTTP/1.1 Status-Lines that omit the Status-Code trailing space character, but it doesn't hurt to follow the specification strictly.

This change fixes #3400

This change adds basic tests ensuring the byteLength argument passed to the RPC-JSON Data constructor and factory method are respected internally, and that they are overridden by the argument passed to toString() and toBuffer().
