## [v5.5.0](https://github.com/tencentyun/cos-cpp-sdk-v5/compare/5.4.5...v5.5.0) - 2021-07-16

1.更新版本号为5.5.0
2.不再单独维护windows_dev分支，多个系统Linux/Windows/macOS等都使用master分支
3.增加logcallback功能，特别在Windows系统下，可以设置日志回调打印日志到自定义日志文件
4.优化日志，日志中打印上传下载速率，方便问题定位
5.优化Makefile，多个系统共用同一套Makefile，支持Linux/Windows/macOS系统，增加编译选项，可以支持编译动态库/编译demo/编译unittest
6.优化UT
7.去掉不必要的库依赖，例如Jsoncpp，OpenSSL，boost等，目前只依赖Poco库，并把相关头文件以及库文件添加到工程目录中，不需要再另行下载依赖库
8.tools目录中增加测速工具，方便问题定位
9.libs目录中添加已编译好的库文件，包括Linux/Win32/Win64/macOS等不同版本，不需要编译代码即可使用sdk
