EOS.IO 3.0的新功能包括交易预设，对于我们未来的区块链业务领域来说，这是一个非常独特而且有趣的新功能。
这个功能让我们能够根据用户注册类型来创造预设的交易。想象一下，你是去中心化的Netflix（著名境外收费视频网站），在大多数区块链平台上，用户们如需支付费用，就不得不登陆平台。但是在我们的新版本中，你可以预设交易，然后在特定情况下，你的费用会被自动支付。还有密码找回功能。在区块链的世界中，你丢失了你的密钥，你的钱就没了。没人喜欢这样。在我们的平台上，你可以通过其它手段或者社交互动媒体账户找回。这是一种植入于我们平台中的图形软件，它对于水平技术能力是非常重要的。
它能够创造重新被主链接纳的侧链。系统中还有500个交叉区块，这是我后面也会讲到的，他们保证了我们平台的性能。此外，我们的新平台还有很多很多的新功能会上线。除了核心平台之外，我们现在还在致力于开发工具，系统生态的研发。
我们的努力方向主要有两方面，一是文件改进，Github建设，另外就是智能合约模版建设。模版建设主要基于Bootstrap， 从而能够在未来让开发者们去开发各种实时及实际应用。我真的要鼓励在座各位中的开发者们或者对于开发有兴趣的同行们对这页幻灯片拍一张照，因为这页幻灯片上的这个链接是关于如何进行实际应用开发并将其部署到EOS测试网络的入门教程。这个教程本身是非常简单，非常使用。在学习完这个教程以后，你就会知道如何操作了。
同时，我们还有内容整合图书馆。一段时间之前，我们开发了一个EOJS ECC， 这是一组图形化低端图书馆，它提供了一系列图形功能。在此之上，图书馆会创建EOJ，这是一个非常低端化的图书馆，它能让开发者和EOS测试网络进行互动，在将来，它还能让开发者和公共网络进行互动。有人也已经开始开发EOJS Estore，这些是高端的应用，它们可以让那些即使是不熟悉加密技术的人们也可以加入进来，让那些即使不是很熟练的开发者们也可以开发应用。接下来我要建议大家也把这个页面拍一张照片，因为通过这些主要链接你可以看到更多关于我们的技术的信息。
这是公告原文地址https://steemit.com/eos/@eosio/dawn-3-0-alpha-announcement
As many in the EOS.IO development community are aware, we've been working since December on merging two lines of development, Dawn 2.x and Dawn 3.0. The merged code base is now stable enough to make public as an Early Alpha and will now become our Github master branch. The prior master will be renamed “dawn-2.x” and will continue to be available as a non-master branch.
Community developers will notice that the next time they “git pull” from Master, they will obtain the new Dawn 3.0 code. Those wishing to continue to pull the Dawn 2.x code that connects to the current TestNet can do so by following instructions in the new readme.md, being made available at the same time as the re-mastering.
Please note that the Dawn 3.0 code is still in Early Alpha and is not compatible with the current block.one-provided public TestNet; it will not be available in a public TestNet until the end of Q1 2018. In the interim, developers may create their own testnets with the new Dawn 3.0 code. As a reminder, Dan Larimer and the development team have changed the way we forecast development. This means we won't be announcing the date for the Dawn 3.0 Testnet until the timeline is close enough for us to have high confidence in its capabilities.
The current public TestNet at “https://testnet1.eos.io” will continue to run the Dawn 2.x software until the release of the Dawn 3.0 Testnet, and will then be retired.
Smart contracts written for the Dawn 2.x codebase will need to be revised to work on the new 3.0 codebase and take advantage of the new features.
Major changes in Dawn 3.0 include changing “eos” to “eosio” in all locations throughout the code. We have also renamed "message" to "action", and removed the need for developers to manually specify 'scope'; all scope specification is now automated.
Additional new features in the Dawn 3.0 Alpha Release include: deferred transactions, staking pools, a new currency contract, and a new emerging token standard. A complete list of new features will be included in the 3.0 Final Release notes, expected by the end of Q1 2018.
