|

<pre>
|
||||
This release includes changes to the http package that will require changes to
|
||||
client code.
|
||||
|
||||
The finalURL return value of the Client.Get method has been removed.
|
||||
This value is now accessible via the new Request field on http.Response.
|
||||
For example, this code:
|
||||
|
||||
res, finalURL, err := http.Get(...)
|
||||
|
||||
should be rewritten as:
|
||||
|
||||
res, err := http.Get(...)
|
||||
if err != nil {
|
||||
// ...
|
||||
}
|
||||
finalURL := res.Request.URL.String()
|
||||
|
||||
Uses of http.Get that assign the finalURL value to _ can be rewritten
|
||||
automatically with gofix.
|
||||
|
||||
This release also includes an optimization to the append function that makes it
|
||||
between 2 and 5 times faster in typical use cases.

||||
