# History
## 3.0.0-beta.2 -> 3.0.0-beta.3
- Complete the Jade Template Engine support, {{ render }} and {{ url }} done also.
- Fix Mail().Send
- Iriscontrol plugin: Replace login using session to basic authentication
And other not-too-important fixes
## 3.0.0-beta -> 3.0.0-beta.2
- NEW: Wildcard(dynamic) subdomains, read [here](https://kataras.gitbooks.io/iris/content/subdomains.html)
- NEW: Implement feature request [#165](https://github.com/kataras/iris/issues/165). Routes can now be selected by `a custom name`, and this allows us to use the {{ url "custom-name" "any" "named" "parameters"}}``: For HTML & Amber engines, example [here](https://github.com/iris-contrib/examples/tree/master/templates_9). For PongoEngine, example [here](https://github.com/iris-contrib/examples/tree/master/templates_10_pongo)
- Remove the [x/net/context](https://godoc.org/golang.org/x/net/context), it has been useless after v2.
## 3.0.0-alpha.beta -> 3.0.0-beta
- New iris.API for easy API declaration, read more [here](https://kataras.gitbooks.io/iris/content/using-handlerapi.html), example [there](https://github.com/iris-contrib/examples/tree/master/api_handler_2).
- Add [example](https://github.com/iris-contrib/examples/tree/master/middleware_basicauth_2) and fix the Basic Authentication middleware
## 3.0.0-alpha.6 -> 3.0.0-alpha.beta
- [Implement feature request to add Globals on the pongo2](https://github.com/kataras/iris/issues/145)
- [Implement feature request for static Favicon ](https://github.com/kataras/iris/issues/141)
- Implement a unique easy only-websocket support:
```go
OnConnection(func(c websocket.Connection){})
```
websocket.Connection
```go
// Receive from the client
On("anyCustomEvent", func(message string) {})
On("anyCustomEvent", func(message int){})
On("anyCustomEvent", func(message bool){})
On("anyCustomEvent", func(message anyCustomType){})
On("anyCustomEvent", func(){})
// Receive a native websocket message from the client
// compatible without need of import the iris-ws.js to the .html
OnMessage(func(message []byte){})
// Send to the client
Emit("anyCustomEvent", string)
Emit("anyCustomEvent", int)
Emit("anyCustomEvent", bool)
Emit("anyCustomEvent", anyCustomType)
// Send via native websocket way, compatible without need of import the iris-ws.js to the .html
EmitMessage([]byte("anyMessage"))
// Send to specific client(s)
To("otherConnectionId").Emit/EmitMessage...
To("anyCustomRoom").Emit/EmitMessage...
// Send to all opened connections/clients
To(websocket.All).Emit/EmitMessage...
// Send to all opened connections/clients EXCEPT this client(c)
To(websocket.NotMe).Emit/EmitMessage...
// Rooms, group of connections/clients
Join("anyCustomRoom")
Leave("anyCustomRoom")
// Fired when the connection is closed
OnDisconnect(func(){})
```
- [Example](https://github.com/iris-contrib/examples/tree/master/websocket)
- [E-book section](https://kataras.gitbooks.io/iris/content/package-websocket.html)
We have some base-config's changed, these configs which are defaulted to true renamed to 'Disable+$oldName'
```go
// DisablePathCorrection corrects and redirects the requested path to the registed path
// for example, if /home/ path is requested but no handler for this Route found,
// then the Router checks if /home handler exists, if yes,
// (permant)redirects the client to the correct path /home
//
// Default is false
DisablePathCorrection bool
// DisablePathEscape when is false then its escapes the path, the named parameters (if any).
// Change to true it if you want something like this https://github.com/kataras/iris/issues/135 to work
//
// When do you need to Disable(true) it:
// accepts parameters with slash '/'
// Request: http://localhost:8080/details/Project%2FDelta
// ctx.Param("project") returns the raw named parameter: Project%2FDelta
// which you can escape it manually with net/url:
// projectName, _ := url.QueryUnescape(c.Param("project").
// Look here: https://github.com/kataras/iris/issues/135 for more
//
// Default is false
DisablePathEscape bool
// DisableLog turn it to true if you want to disable logger,
// Iris prints/logs ONLY errors, so be careful when you enable it
DisableLog bool
// DisableBanner outputs the iris banner at startup
//
// Default is false
DisableBanner bool
```
## 3.0.0-alpha.5 -> 3.0.0-alpha.6

## 3.0.0-alpha.3 -> 3.0.0-alpha.4
Community suggestions implemented:
- [Request: Rendering html template to string](https://github.com/kataras/iris/issues/130)
> New RenderString(name string, binding interface{}, layout ...string) added to the Context & the Iris' station (iris.Templates().RenderString)
- [Minify Templates](https://github.com/kataras/iris/issues/129)
> New config field for minify, defaulted to true: iris.Config().Render.Template.Minify = true
> 3.0.0-alpha5+ this has been removed because the minify package has bugs, one of them is this: https://github.com/tdewolff/minify/issues/35.
Bugfixes and enhancements:
- [Static not allowing configuration of `IndexNames`](https://github.com/kataras/iris/issues/128)

## 3.0.0-alpha.2 -> 3.0.0-alpha.3
The only change here is a panic-fix on form bindings. Now **no need to make([]string,0)** before form binding, new example:
```go
//./main.go
package main
import (
"fmt"
"github.com/kataras/iris"
)
type Visitor struct {
Username string
Mail string
Data []string `form:"mydata"`
}
func main() {
iris.Get("/", func(ctx *iris.Context) {
ctx.Render("form.html", nil)
})
iris.Post("/form_action", func(ctx *iris.Context) {
visitor := Visitor{}
err := ctx.ReadForm(&visitor)
if err != nil {
fmt.Println("Error when reading form: " + err.Error())
}
fmt.Printf("\n Visitor: %v", visitor)
})
fmt.Println("Server is running at :8080")
iris.Listen(":8080")
}
```
