2.1.1-beta.0 - Croquembouche 🔺

 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

I've never had Croquembouche, but it looks delicious!

This version of Ganache is full of bug fixes and dependency updates.

Dependencies updated in this version:

• async to v2.6.2
• debug to 3.2.6
• eth-sig-util to 2.2.0
• ethereumjs-abi to 0.6.7
• ethereumjs-account to 3.0.0
• ethereumjs-block to 2.2.0
• ethereumjs-util to 6.1.0
• ethereumjs-vm to 3.0.0
• lodash to 4.17.14

We haven't updated ethereumjs-tx yet as there is a little more legwork we'll need to do in order to get transaction signing working properly with the latest version.

2.1.0 - Candy-Covered Cactus Pretzel Rods 🍬🌵🥨

 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

First of all, Candy-Covered Cactus Pretzel Rods are a real thing. Google it.

Secondly, this version of Ganache beta introduces a new feature: eth_chainId (finally)! eth_chainId is currently hard-coded to return 1337; we'll be making this value configurable in a future release. We've also got some bug fixes related to forking in this release as well.

2.0.3 - Banana Pudding 🍌

 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

This version of Ganache UI features the latest and greatest gas exactimation algorithm from the latest ganache-core. While the previous algorithm works well in most cases and was heavily tested, it relied on several assumptions we later found to be incorrect. Gas exactimation 2.0 now makes ZERO assumptions, and returns an exactimation in O(1), compared with O(log n) in geth, parity, etc!

Some notable improvements you might like:

• Completely rewritten without recursion
• Approximately 20% faster and 33% less code
• Works with CREATE2

Stay tuned for a full featured blog post explaining the algorithm and a "Deep Dive" workshop at TruffleCon 2019!

2.0.2 - ✨ Mystery Flavor ✨

 Highlights    How to Upgrade

Another bug-fix release here. 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!

Our beta releases shouldn't introduce any new bugs, but it's very possible we've messed something up. If you'd like the latest-and-greatest Ganache features and fixes, but possibly a little less stable, the betas are for you!

Highlights

In this latest version we've fixed some issues introduced with the initial 2.0.0 release, specifically issues with decoding contracts.

We've also updated ganache-core, the gooey center powering Ganache UI, to its latest version. This update adds support for binary data over websockets, updates eth-sig-util to fix a global variable leak, and some other bugs, too!

v2.0.0 - Chocolate Birthday Cake 🎂

The snow is melting and birds are chirping once again. 🐣 A mild breeze wafts over the smell of freshly baked chocolate cake – it's finally ready! 🎂

Version 2.0.0 adds a number of new features aimed at making dapp development easier and more akin to the modern development experience we expect from other platforms. We hope you enjoy this tasty treat and thank the community for their work and support in getting this release out of the oven!

Contents

• New Features
  • Workspaces
  • Contract State Decoding
  • Event Decoding
• New Options
  • Hardfork
• Changelog
• Acknowledgements

New Features

Workspaces

^{[ ∧ Back to Contents ]}

You can now save your development blockchains in workspaces. These workspaces contain the configuration of your development chain, along with any Truffle projects you've provided to decode contract and event data. We haven't forgotten the convenience of a one-click blockchain though! Select the QUICKSTART option on the home screen for a familiar Ganache initialization experience.

📖 Pertinent Docs:

• Creating Workspaces
• The Quickstart Workspace

Contract State Decoding

^{[ ∧ Back to Contents ]}

The new Contracts page contains a list of your smart contracts by project. At a glance we can see the contract's name, address, transaction count, and deployment status.

📖 Pertinent Docs:

• Linking a Truffle Project
• Contracts Page

Event Decoding

^{[ ∧ Back to Contents ]}

The new events page shows the events that have fired during this chain's life. We'll try to decode the events if possible. A decoded event will show its name, the emitting contract, hash of the transaction it appears in, log index, and block time. Encoded events will not display decoded names (they appear instead with the generic name Encoded Event) or contract names.

📖 Pertinent Docs:

• Linking a Truffle Project
• EventsPage

New Options

Hardfork

^{[ ∧ Back to Contents ]}

Ganache now features an option to change the hardfork. Possible options are: Petersburg, Constantinople, and Byzantium.

Changelog (Since 2.0.0-beta.2)

^{[ ∧ Back to Contents ]}

New Features

• #1107 Add hardfork indicator to status bar (@davidmurdoch)
• #1109 Update ganache-core to v2.4.0 and add Byzantium + Constantinople hardfork options (@davidmurdoch)

Acknowledgements

^{[ ∧ Back to Contents ]}

We mentioned this in the beta.1 notes, but it bears repeating: Ganache 2.0 has been on the drawing board for awhile, and it has taken several months to complete. We'd like to thank the community for their support and patience while we implemented these features! Also thank you to the devs who made this vision happen: @seesemichaelj, @honestbonsai, @adrianmcli, @nicholasjpaterno, @eshaben and @davidmurdoch. 🤗
