 ### 改动
 
++ 删除了一些无用的日志（[bd279e7](https://github.com/ADD-SP/ngx_waf/commit/bd279e7be872621fa75337722a9fae30b2ea6812)）。

 + 友好的错误提示（[d1185b2](https://github.com/ADD-SP/ngx_waf/commit/d1185b26a413e45dcf5ef479b0078aa57a4b5962) & [f2b617d](https://github.com/ADD-SP/ngx_waf/commit/f2b617d5174eb1bc6982113415ddcb1f798ef703)）。当规则文件中 IP 地址无效或者 IP 地址块重叠的时候警告或者报错（并不能检测所有的重叠情况）。
 
 + 更快的 IP 地址检查速度（[2b9e774](https://github.com/ADD-SP/ngx_waf/commit/2b9e77404826666df301c3d6b3ce07a6968de266)）。改用前缀树检查 IP，现在在常数时间内即可完成 IP 的匹配，之前是一个一个地匹配，是线性时间。

 ### Changed
 
++ Delete some meaningless logs ([bd279e7](https://github.com/ADD-SP/ngx_waf/commit/bd279e7be872621fa75337722a9fae30b2ea6812)).
+
 + Friendly error alerts ([d1185b2](https://github.com/ADD-SP/ngx_waf/commit/d1185b26a413e45dcf5ef479b0078aa57a4b5962) & [f2b617d](https://github.com/ADD-SP/ngx_waf/commit/f2b617d5174eb1bc6982113415ddcb1f798ef703)). Warnings or error reporting when IP addresses in the rule file are invalid or IP address blocks overlap (does not detect all overlaps).
 
 + Faster IP matching ([2b9e774](https://github.com/ADD-SP/ngx_waf/commit/2b9e77404826666df301c3d6b3ce07a6968de266)).
