Fork slayer (0.9.26)
This is a mandatory update and helps to improve the network's stability through several upgrade mechanism and download policies.
This release will go down in history as the fork slayer :-)
Olympic Release (0.9.25)
This update fixes two things:
- Hardcode a block's header hash so that when it encounters it in your blockchain revert back the valid parent and from there on get back on the right track. All clients which catch up from anything previous to the invalid block won't have any issue and might not even notice the bad chain.
- Fixes an issue within the Ethereum VM's memory when doing a sub-call (op codes
CALL
&CALLCODE
). When doing a sub-call you reserve a bit of memory for the sub-calls return data and write to that memory region when the sub-call returns. The subtle change is that previously Geth would zero out the memory and then write, now it doesn't zero and write directly. Here's an example of the before and after
Before:
Mem before call = [1,1,1,1,1,1,1,1,1,1]
Sub calls returns = [6,6]
Mem after call = [6,6,0,0,0,0,0,0,0,0]
After:
Mem before call = [1,1,1,1,1,1,1,1,1,1]
Sub calls returns = [6,6]
Mem after call = [6,6,1,1,1,1,1,1,1,1]
This update also includes a re-work of the p2p
dialing mechanism.

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
.

Olympic Release (0.9.21.1)
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.

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.
