Olympic release comes with many improvements to the CLI tools and includes a fully programmable JavaScript interface and JavaScript REPL (Read Evaluate Print Loop). We've also added support for solidity using the solidity stand-alone compiler: solc.

The CLI has seen a massive overhaul in usability and CLI utilities. For a complete list of utils and tools please run geth help or get help topic for a detailed description.

We're also in the process of writing a Frontier GitBook. Please note that this book is a work in progress and will serve as the main guide for frontier once released.

Installation instructions

Build instructions for OSX, Windows and Linux can be found here.

Upgrade from <0.9.20

If you have accounts in your wallet that you'd like to keep you need export them first first with the gethkey tool found here. Download and install and run the following for each of the accounts you'd like to keep:

mkdir -p ~/export_keys
gethkey <account_address> ~/export_keys/account_address
geth account import ~/export_keys/account_address

When you've verified and imported all of your keys rm -rf ~/export_keys.

If you've been encountering INVALID block #xxxx run a geth upgradedb after you've updated (ignore any errors it encounters). When it's done re-run geth as you normally do.

Previous release notes

Mist (Ether Browser)

note: Windows binaries will be uploaded soon™

This is the first release of the proof of concept ether browser named Mist. Mist is PoC6 ready and has the following improvements and features:

• HTML ĐApp development.

JavaScript API now aligns better with the regular calling convention that C++ uses (getMethod vs method) while still remaining fully async using Promisees.

• QML ĐApp development.

The QML API is far from finished but shares common methods with the JavaScript API (just without the promises) and a few additional methods. A sample application is provided in Mist; JeffCoin. The source code can be found in the mist repo.

• Mutan 0.5
  • { /* code */ } style to define a new local scope.
  • else if statement.
  • Logical and and or (&& ||)
  • this changed in favour of message
• Improved debugger (Mutan stack info)
• Embedded HTML renderer.

This release fixes and improves the following:

• Improved catching up. Previous build would sometimes fail to catch up or stop for no obvious reason. This should now be fixed
• Fixed the VM. This caused issues with processing certain contracts.
• If a connection fails to a peer it will continue trying for a couple of times.
• Peers can be pushed towards clients even when the clients hasn't asked for it. Previously builds would ignore the peer server's peer message.
• Fixed retina issue
• Faster startup time

Additionally I've decided to give some flavour to the releases; names of satellites.
