SN-10169 附来源、原文与上下文。
我把 0.3.0 beta 上传到了 SourceForge，并更新了 bitcoin.org 上的链接。还需要在论坛和邮件列表发布公告。下面是我准备的内容：
I uploaded 0.3.0 beta to sourceforge and updated the links on bitcoin.org. I still need to post the announcement message on the forum and mailing list. Here's what I've prepared:
宣布推出点对点加密货币 Bitcoin 的 0.3 版！比特币是一种数字货币，使用密码学和分布式网络，取代对可信中央服务器的需求。摆脱集中管理货币的任意通胀风险！比特币总流通量限制为 2100 万个币。这些币正根据网络节点贡献的 CPU 算力，逐步发行给节点。只要安装软件，贡献空闲 CPU 时间，你就能获得其中一份。
Announcing version 0.3 of Bitcoin, the P2P cryptocurrency! Bitcoin is a digital currency using cryptography and a distributed network to replace the need for a trusted central server. Escape the arbitrary inflation risk of centrally managed currencies! Bitcoin's total circulation is limited to 21 million coins. The coins are gradually being released to the networks nodes based on the CPU power they contribute. You can get a share of them just by installing the software and contributing your idle CPU time.
