GXChain的网络由于出现出块奖励计算溢出，导致出块失败，目前已经完成修复，所有的节点需要升级程序以实现正常出块

修复代码：

• dc3d967
• 84c3332

升级方式：所有的节点需要替换节点程序后重启节点，来完成升级

下载地址：https://github.com/gxchain/gxb-core/releases/tag/v1.0.201217

升级步骤

1. 下载解压最新节点程序：
   wget 'https://github.com/gxchain/gxb-core/releases/download/v1.0.201217/gxb_1.0.201217-ubuntu-14.04.tar.gz' -O gxb_1.0.201217-ubuntu-14.04.tar.gz && tar zxvf gxb_1.0.201217-ubuntu-14.04.tar.gz

2. 安全停止witness_node:

kill -s SIGINT $(pgrep witness_node)

3. 重启

# 使用原来的启动方式进行启动: history|grep witness_node
nohup ./programs/witness_node/witness_node [other-options]

提示：如果你的是一个出块节点（BP），由于升级不及时可能已经被系统自动关进小黑屋，无法参与出块，可以在 https://wallet.gxb.io 导入账户活跃权限私钥后，在资料页面进行操作，离开小黑屋

This release modified the voting logic form "multiple vote"(one vote to an unlimited number of accounts) to "one token, one vote" (each token can vote to only one account). From now on the reward as a node is divided into two parts. The first part is for the node which producing the block, and the other part is the nodes which's weight of the voting ranking must be top "35"(The number is not fixed and could be modified by the commission proposals) in all nodes.This release also contains the new contract api and database api.

New features:

• Add smart contract api: get_asset_precision

• Add the cli_wallet api: staking_claim, which can be used to withdraw the staking when the vote has expired
• Add the cli_wallet api: witness_set_commission, the witness can set the dividend ratio with it
• Add the cli_wallet api: witness_unbanned, which can be used to release the witness form the blacklist
• Add the database api: get_staking_objects, you can get the staking objects of one account with it
• Add the database api: get_staking_objects_by_witness,this api is to get staking objects with specified witness_id, position and number
• Add the macro
