## v4.2.2 - 2021-04-07
**Fixes**
* Allow proxy middleware to use query part in rewrite (#1802)
* Fix timeout middleware not sending status code when handler returns an error (#1805)
* Fix Bind() when target is array/slice and path/query params complains bind target not being struct (#1835)
* Fix panic in redirect middleware on short host name (#1813)
The behaviour for binding data has been reworked for compatibility with echo before v4.1.11 by
enforcing `explicit tagging` for processing parameters. This **may break** your code if you
expect combined handling of query/path/form params.
Please see the updated documentation for [request](https://echo.labstack.com/guide/request) and [binding](https://echo.labstack.com/guide/request)
The handling for rewrite rules has been slightly adjusted to expand `*` to a non-greedy `(.*?)` capture group. This is only relevant if multiple asterisks are used in your rules.
Please see [rewrite](https://echo.labstack.com/middleware/rewrite) and [proxy](https://echo.labstack.com/middleware/proxy) for details.
