  Effect: The latest features of the current version can be used

  Operation: First finish upgrading all node executables, then refer to documentation to send the transaction upgrade chain data version to v3.4.0

  Note: Be sure to backup all the book data of the original node, if the upgrade fails due to an operation error, you can roll back to the state before the upgrade through the original data Versions supported for upgrade: v3.0.0+

新增

• 块内分片：将合约分组，相同分片（分组）的交易调度到相同的执行器执行，片间采用DMC调度保证一致性，片内采用DAG调度保持高性能

• 权限动态可配：可在运行时动态关闭/开启权限功能

• SDK支持硬件加密机：SDK支持通过加密机运行密码学算法

• 网关入限速：通过配置文件 (config.ini) 控制入流量大小

• Merkle树缓存：提升取交易证明的性能

• 网关模块支持多CA：不同的链可共用同一个网关模块转发消息

修改

• 优化各种细节，提升节点性能至10万TPS
• rpc的交易接口返回input字段：可在配置文件中控制是否需要返回

升级描述

• 升级节点可执行程序

  效果：修复bug，并带来稳定性、性能的提升

  操作：停止节点服务，升级节点可执行程序为当前版本，重启节点服务

  注意事项：推荐逐步替换可执行程序进行灰度升级

  支持升级的版本：v3.0.0+

• 升级链数据版本

  效果：可使用当前版本的最新特性

  操作：先完成升级所有节点可执行程序，再参考文档发送交易升级链数据版本至 v3.3.0

  注意事项：务必备份原节点的所有账本数据，若操作失误造成升级失败，可通过原数据回滚到升级前的状态 支持升级的版本：v3.0.0+

Added

• Intra-block Sharding: Group contracts and schedule transactions to different executors for execution according with the groups.
• Dynamic Permission Configuration: Dynamic disabling/enabling of permission checking at runtime.
• SDK support for Hardware Security Module (HSM): SDK supports cryptographic algorithms through an HSM.
• Gateway In-traffic Control：Use config.ini to control gateway inbound traffic.
• Merkle Tree Cache: Improve the performance of getting transaction proof.
• Gateway module supports multiple Certificate Authorities (CA): Different chains can share the same gateway module to forward messages.

Changed

• Optimized various details to improve performance.
• Control sendTransaction(RPC) return inputs param: Can be controlled whether to return or not in the configuration file.

Upgrade Notice

• Upgrade node executable

  Effect: Fix bugs, and bring stability and performance improvements

  Operation: Stop the node service, upgrade the node executable to the current version, and restart the node service

  Notice: It is recommended to gradually replace the executable for a phased upgrade

  Versions supported before upgration: v3.0.0+

• Upgrade chain data version

  Effect: Can use the latest features of the current version

  Operation: First complete the upgrade of all node executables, then refer to the documentation to send a transaction to upgrade the chain data version to v3.3.0

  Notice: Be sure to back up all ledger data of the original node. If the operation is incorrect and the upgrade fails, you can roll back to the state before the upgrade using the original data.

  Versions supported before upgration: v3.0.0+
