This is a release that mainly fixes a crash that might occur during the Homestead transition if there are too many non-Homestead nodes. We also further aligned the account management functionality of eth with the one used by geth, so eth wallet and eth account can now be used.



  • updated version information
  • fixed crash when account list is empty(when deleting web3 directory for ex.)
  • UI fixes


  • fixed sync issues that appear when large forks are present (thanks, @arkpar !)
  • Change data dir via -d and move IPC socket with it
  • Provide eth wallet and eth account interfaces to wallet similar to geth
  • Provide network id via RPC
  • Removed StructuredLogger
  • Various build fixes
  • Change default gas price and block gas limit ethereum/libethereum#201


Please see Version 0.3.0 Changelog

Compatibility Changes and Security Considerations

The native eth Javascript console will be removed soon. Please switch over to use the new ethconsole application or geth attach to control it.
The rpc admin interface of eth should not be used via HTTP anymore for security reasons. If you must, you can enable it via a command-line switch (see --help).

AlethZero is still included in this release but will be slowly phased out during the next releases.
