metamask-extension

• Includes a major restructuring of how messages are passed internally, so many bugs should be fixed! (Hopefully not created!)
• Add ability to import accounts in JSON file format (used by Mist, Geth, MyEtherWallet, and more!)
• Fix unapproved messages not being included in extension badge.
• Fix rendering bug where the Confirm transaction view would lets you approve transactions when the account has insufficient balance.

BugFix: When clicking "New Account" it would sometimes select the wrong keychain.

Fixed bug where that stubborn little fox would not let go of its seed phrase.

• Add ability to import accounts by private key.
• Fixed bug that returned the wrong transaction hashes on private networks that had not implemented EIP 155 replay protection (like TestRPC).

Much like a squid emits ink when scared, this quick patch fixes MetaMask's ability to sign messages.

• Fixed bugs that prevented eth.sign from working.

A long time in the making, Version 3.0.0: Coy Cuttlefish includes some major changes under the hood, that will allow some very cool things in the near future! (Importing accounts! Multiple account types!)

For now, we're publishing this work, packed full of bug fixes and enhancements, and we think you'll find MetaMask to be working smoother than ever!

This is a major version bump, because we've changed how we generate accounts under the hood, and although we're temporarily migrating the old type of accounts, eventually MetaMask users with older types of accounts will not be compatible with the latest version, when we remove a lot of excess code.

All you have to do is sign into your metamask account with this new version sometime in the next several months, and your account will be automatically updated to use much more efficient code, that will eventually speed up MetaMask even more!
