新增

• 实现Web3 Json RPC接口，用户可以使用Hardhat、OpenZeppelin 等现有Web3开发工具在FISCO BCOS上进行调试。相关PR: #4334, #4337, #4356，#4365
• 支持RLP交易类型的解析以及执行。相关PR：#4347，#4350，
• 新增事件拉取接口，用户可以使用主动拉取的方式收取合约事件、区块变化等。相关PR：#4403 ， #4412，[#4440]](#4440)
• 新增系统配置项web3_chain_id，用于Web3工具识别链的ID，发送正确的交易。相关PR：#4392
• 新增配置项[web3_rpc]，用户可选择开启Web3 Json RPC服务，默认端口号为8545。

修复

• 修复在Solidity合约中使用staticcall的opcode调用合约异常时返回错误的问题。相关PR：#4443
• 修复在Solidity合约中receive函数没有被正确处理的问题。相关PR：#4443
• 修复在Solidity合约中获取EOA的code时返回错误的问题。相关PR：#4505
• 修复在调用Solidity合约view函数时，合约内取区块高、时间戳错误的问题。相关PR：#4505

兼容性说明

兼容版本

需要升级的链的“数据兼容版本号（compatibility_version）”为如下版本时：

• 3.4.x、3.5.x，3.6.x、3.7.x、3.8.x：数据完全兼容当前版本，直接替换二进制即可完成升级
• 3.3.x、3.2.x、3.1.x、3.0.x：支持通过替换二进制进行灰度升级，若需使用当前版本的新特性，需升级数据兼容版本号，操作见文档
• 3.0-rc x：数据不兼容，无法升级，可考虑逐步将业务迁移至3.x正式版
• 2.x：数据不兼容，2.x版本仍持续维护，可考虑升级为2.x的最新版本

升级方法

该操作仅支持将3.x版本升级为本版本，不支持3.0-rc或2.x的升级。

查询数据兼容版本号（compatibility_version）

用控制台
进行查询，如当前返回的版本为3.7.0

[group0]: /apps>  getSystemConfigByKey compatibility_version
3.7.0

替换节点二进制

需将所有节点
的二进制逐步替换为当前版本。为了不影响业务，替换过程能够以灰度方式进行，逐个替换并重启节点。替换过程中，当前的链仍然会以旧的数据兼容版本号的逻辑继续执行。当所有节点二进制替换完成并重启后，需用控制台修改数据兼容版本号为当前版本。

设置数据兼容版本号（compatibility_version）

用控制台
设置数据兼容版本号，如当前版本为3.7.0。

[group0]: /apps>  setSystemConfigByKey compatibility_version 3.9.0
{
    "code":0,
    "msg":"success"
}

注：若开启权限治理功能，需要使用 setSysConfigProposal 命令

设置成功，再次查询，得到当前版本已升级为3.9.0

[group0]: /apps>  getSystemConfigByKey compatibility_version
3.9.0

当前链已经完成升级，至此，链开始以新的逻辑继续运行，并支持了新的特性。
