+## v4.2.1 - 2020-03-08
+
+**Important notes**
+
+Due to a datarace the config parameters for the newly added timeout middleware required a change.
+See the [docs](https://echo.labstack.com/middleware/timeout).
+A performance regression has been fixed, even bringing better performance than before for some routing scenarios.
+
+**Fixes**
+
+* Fix performance regression caused by path escaping (#1777, #1798, #1799, aldas)
+* Avoid context canceled errors (#1789, clwluvw)
+* Improve router to use on stack backtracking (#1791, aldas, stffabi)
+* Fix panic in timeout middleware not being not recovered and cause application crash (#1794, aldas)
+* Fix Echo.Serve() not serving on HTTP port correctly when TLSListener is used (#1785, #1793, aldas)
+* Apply go fmt (#1788, Le0tk0k)
+* Uses strings.Equalfold (#1790, rkilingr)
+* Improve code quality (#1792, withshubh)

+## v4.2.0 - 2020-02-11
+
+**Important notes**
+
+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.
