 #### 2022-01-04
 version: github.com/huaweicloud/devcloud-go v0.1.1  
 feature:
 1. mock package add etcd mock, replace test cases that rely on real etcd.
 
-#### 2021-12-27
-version: github.com/huaweicloud/devcloud-go v0.1.0  
-feature:
-1. add dms package, which is a high performance and high reliability kafka consumer.
-2. add mock package, which can mock redis, mysql and interface.
 #### 2021-12-25
 1. dms: persist the first N continuous offsets in offsetNode to the database and kafka broker, this will reduce repeated consumption of messages.
 2. change dms/method.go BizHandler from interface to function types.
 #### 2021-12-24
 1. add mock package, which contains interface mock, redis mock and mysql mock.
 
 #### 2021-12-16

 # Devcloud-go
 
 Devcloud-go provides a sql-driver for mysql, a redis client and a kafka consumer which named dms, you can use the driver and redis client with MAS or use them separately,
+at the same time, they also support use cases with injection faults for scenario simulation.
 The driver is developed based on [go-sql-driver/mysql v1.6.0](https://github.com/go-sql-driver/mysql), the redis client is developed based on [go-redis v8.11.3](https://github.com/go-redis/redis).
 The kafka consumer is developed based on [github.com/Shopify/sarama v1.29.1](https://github.com/Shopify/sarama).
+The mock package provides the simulation of MySQL, redis and etcd services, and realizes the fault injection function of MySQL and redis through TCP.
 This document introduces how to obtain and use Devcloud-go.
