1、 Sharder将于2018年3月18日发放早鸟和私募阶段代币的同时启用新的合约升级豆匣代币。届时也会同步最新的豆匣代币v2.0的合约地址。

2、 和目前准备上架的交易所协商后，为了增加辨识度代币名称将由Sharder Storage (SS)变成Sharder (SS)。

3、 增加全局变量以避免出现IDEX类似的交易平台在未和豆匣官方建立合作前就开放豆匣代币交易的情况。

4、 邀请审计组织和Nuls的技术顾问Rui对豆匣代币的合约进行审计后，根据审计意见作出以下改善：a)增加owner的转移功能；b)按照标准的MintToken移除掉Crowdsale相关逻辑，保持豆匣合约代码的整洁性和易读性；c)增加event广播frozen；d)name、symbol、decimal等变量按照习惯调整为小写；e)增加必要的注释说明。

5、 增加了全局数组ssHolders和兑换功能以记录所有的Sharder (SS)的持有者，便于今年晚些时候豆匣链主网上线后，能够顺利将ERC-20的Sharder (SS)兑换回豆匣链。

6、 增加锁仓和锁仓查询功能，以便用户自主查询剩余锁仓时间以及后续不定期开放的锁仓活动。

7、 对于crowdsale阶段已经兑换到个人ETH钱包的用户，将根据Etherscan上持币账户的快照

(https://etherscan.io/token/0xB15fE5a123e647ba594CEa7A1E648646f95EB4AA#balances)按照 1:1 的比例将升级后的 Sharder(SS)发放到您的ETH地址。
