 ## Fixes and Improvements
 
+- New `versioning.Aliases` middleware. Example Code:
+
+```go
+app := iris.New()
+
+api := app.Party("/api")
+api.Use(Aliases(map[string]string{
+    versioning.Empty: "1", // when no version was provided by the client.
+    "beta": "4.0.0",
+    "stage": "5.0.0-alpha"
+}))
+
+v1 := NewGroup(api, ">= 1, < 2")
+v1.Get/Post...
+
+v4 := NewGroup(api, ">= 4, < 5")
+v4.Get/Post...
+
+stage := NewGroup(api, "5.0.0-alpha")
+stage.Get/Post...
+```

+- New [Basic Authentication](https://github.com/kataras/iris/tree/master/middleware/basicauth) middleware. Its `Default` function has not changed, however, the rest, e.g. `New` contains breaking changes as the new middleware features new functionalities.
 - Add `iris.DirOptions.SPA bool` field to allow [Single Page Applications](https://github.com/kataras/iris/tree/master/_examples/file-server/single-page-application/basic/main.go) under a file server.
 - A generic User interface, see the `Context.SetUser/User` methods in the New Context Methods section for more. In-short, the basicauth middleware's stored user can now be retrieved through `Context.User()` which provides more information than the native `ctx.Request().BasicAuth()` method one. Third-party authentication middleware creators can benefit of these two methods, plus the Logout below. 
 - A `Context.Logout` method is added, can be used to invalidate [basicauth](https://github.com/kataras/iris/blob/master/_examples/auth/basicauth/basic/main.go) or [jwt](https://github.com/kataras/iris/blob/master/_examples/auth/jwt/blocklist/main.go) client credentials.
