 # Changelog
 
+## 1.0
+
+ * Remove the old API: `NewConnWith`, `WithPrefix` and etc and move to a simple `New` function.
+ * Prefix is no longer supported in this package.
+ * Change the Hook structure to have only two members: `logrus.Formatter` and `io.Writer`.

 ## 0.4
 
  * Update the name of the package from `logrus_logstash` to `logrustash`

-## Hook Fields
-Fields can be added to the hook, which will always be in the log context.
-This can be done when creating the hook:
 
-```go
+# Maintainers
-
-hook, err := logrustash.NewHookWithFields("tcp", "172.17.0.2:9999", "myappName", logrus.Fields{
-        "hostname":    os.Hostname(),
-        "serviceName": "myServiceName",
-})
-```
-
-Or afterwards:
-
-```go
-
-hook.WithFields(logrus.Fields{
-        "hostname":    os.Hostname(),
-        "serviceName": "myServiceName",
-})
-```
-This allows you to set up the hook so logging is available immediately, and add important fields as they become available.
-
-Single fields can be added/updated using 'WithField':
-
-```go
-
-hook.WithField("status", "running")
-```
-
-
-
-## Field prefix
-
-The hook allows you to send logging to logstash and also retain the default std output in text format.
-However to keep this console output readable some fields might need to be omitted from the default non-hooked log output.
-Each hook can be configured with a prefix used to identify fields which are only to be logged to the logstash connection.
-For example if you don't want to see the hostname and serviceName on each log line in the console output you can add a prefix:
-
-```go
-
-
-hook, err := logrustash.NewHookWithFields("tcp", "172.17.0.2:9999", "myappName", logrus.Fields{
-        "_hostname":    os.Hostname(),
-        "_serviceName": "myServiceName",
-})
-...
-hook.WithPrefix("_")
-```
-
-There are also constructors available which allow you to specify the prefix from the start.
-The std-out will not have the '\_hostname' and '\_servicename' fields, and the logstash output will, but the prefix will be dropped from the name.
