+1. 对常用的字符串模块: `gstr`做了大量改进/完善工作，新增大量常用方法，并完善单元测试用例及方法注释，详见API文档：https://godoc.org/github.com/gogf/gf/g/text/gstr
+1. 改进`gform`中对`struct`/`*struct`参数的支持，`*Insert/*Save/*Replace/*Update/Where/Data`方法的参数调整为`interface{}`类型，并支持任意类型的: `string/map/slice/struct/*struct`参数传递，具体请参考：https://goframe.org/database/orm/chaining
+1. 新增/完善若干模块的单元测试用例, 包括：`gvalid`/`gregex`/`garray`/`gset`/`gmap`/`gstr`/`gconv`/`ghttp`/`gdb`；
+1. 由于`gkafka`模块比较重，且不是框架核心模块，因此将该模块迁移到新的仓库中独立管理，并去掉相关依赖包：https://github.com/gogf/gkafka
+1. 新增`greuseport`模块，用以实现TCP的`REUSEPORT`特性：https://godoc.org/github.com/gogf/gf/g/net/greuseport
+
+## 新功能/改进
+1. 去掉模板引擎内置变量中自动初始化`session`对象带来的内存占用问题；
+1. `ghttp.Client`改进，增加若干方法，详见：https://goframe.org/net/ghttp/client 
+1. `ghttp`分组路由增加`COMMON`方法，用以注册常用的`HTTP METHOD`(`GET/PUT/POST/DELETE`)路由；
+1. 更新框架依赖的`golang.org/x/sys`模块；
+1. 改进`gform`的批量操作(`Batch*`操作)返回结果对象，可以通过该结果对象获得批量操作准确的受影响记录行数；
+1. 将`gstr`/`gregex`模块从`util`分类迁移到了`text`分类目录下；
+1. 将`gtest`模块从`util`分类迁移到了`test`分类目录下；

+1. 修复`gcron`模块定时规则中天和周不允许`?`符号的问题；
+1. 修复`ghttp.Server`在部分异常情况下仍然返回`200`状态码的问题；
+1. 修复`gfpool`模块中由于原子操作问题造成的高并发"内存泄露"问题；
+1. 修复分组路由注册对象/控制时，方法`Index`的路由仅能通过`/xxx/index`访问的问题；
+1. 修复模板引擎使用中，当不存在`config.toml`(即使没使用)配置文件时的报错问题；
+1. 其他一些修复；
+
+
+
+# `v1.4.6` (2019-01-24)
+
+## 新特性
+1. 新增并发安全的高性能任务定时器模块`gtimer`, 类似于Java的`Timer`，但是比较于Java的`Timer`更加强大，内部实现采用灵活高效的`分层时间轮`设计，被设计为可管理维护百万级别以上数量的定时任务。`gtimer`为`GF`框架的核心模块之一，单元测试覆盖率达到`93.6%`：[https://goframe.org/os/gtimer/index](https://goframe.org/os/gtimer/index)
+1. 采用任务定时器`gtimer`重构`gcron`定时任务模块，去掉第三方`github.com/robfig/cron`包的使用。`gcron`增加单例模式的定时任务：[https://goframe.org/os/gcron/index#](https://goframe.org/os/gcron/index#)；
+1. `gconv`类型转换模块支持对`struct`结构体中的**指针属性**转换：[https://goframe.org/util/gconv/struct](https://goframe.org/util/gconv/struct)；
+1. `gform`增加对数据库类型的自动识别特性，这一特性在需要将查询结果`json`编码返回时非常有用: [https://goframe.org/database/orm/index](https://goframe.org/database/orm/index)
+1. `Travis CI`增加对`386`架构的自动化测试支持(目前已支持`386`和`amd64`)；
+
+## 新功能
+1. `ghttp`模块新增`Exit`、`ExitAll`、`ExitHook`方法，用于HTTP请求处理流程控制: [https://goframe.org/net/ghttp/service/object](https://goframe.org/net/ghttp/service/object)；
+1. `grand`模块增加`Meet/MeetProb`方法，用于给定概率的随机满足判断，增加别名方法`N/Str/Digits/Letters`；
+1. `gvalid`数据/表单校验模块增加`16X`及`19X`手机号的校验支持；
+
+## 功能改进
+1. `gform`设置默认的数据库连接池`CONN_MAX_LIFE`参数值为`30`秒；
+1. 改进`glist`模块，提高约`20%`左右性能，并增加若干链表操作方法；
+1. 改进`gqueue`模块，提高约`50`左右性能，并增加模块对`select`语法的支持(使用`Queue.C`): [https://goframe.org/container/gqueue/index](https://goframe.org/container/gqueue/index)；
+1. 改进`gmlock`内存锁模块，并完善单元测试用例：[https://goframe.org/os/gmlock/index](https://goframe.org/os/gmlock/index)；
+1. 改进并发安全容器所有的模块，调整并发安全控制非必需参数`safe...bool`为`unsafe...bool`；
+1. 改进`gpool`对象复用模块，支持并发安全；
