# Changelog
## v4.6.1 - 2021-09-26
**Enhancements**
* Add start time to request logger middleware values [#1991](https://github.com/labstack/echo/pull/1991)
## v4.6.0 - 2021-09-20
Introduced a new [request logger](https://github.com/labstack/echo/blob/master/middleware/request_logger.go) middleware
to help with cases when you want to use some other logging library in your application.
**Fixes**
* fix timeout middleware warning: superfluous response.WriteHeader [#1905](https://github.com/labstack/echo/issues/1905)
**Enhancements**
* Add Cookie to KeyAuth middleware's KeyLookup [#1929](https://github.com/labstack/echo/pull/1929)
* JWT middleware should ignore case of auth scheme in request header [#1951](https://github.com/labstack/echo/pull/1951)
* Refactor default error handler to return first if response is already committed [#1956](https://github.com/labstack/echo/pull/1956)
* Added request logger middleware which helps to use custom logger library for logging requests. [#1980](https://github.com/labstack/echo/pull/1980)
* Allow escaping of colon in route path so Google Cloud API "custom methods" could be implemented [#1988](https://github.com/labstack/echo/pull/1988)
## v4.5.0 - 2021-08-01
**Important notes**
A **BREAKING CHANGE** is introduced for JWT middleware users.
The JWT library used for the JWT middleware had to be changed from [github.com/dgrijalva/jwt-go](https://github.com/dgrijalva/jwt-go) to
[github.com/golang-jwt/jwt](https://github.com/golang-jwt/jwt) due former library being unmaintained and affected by security
issues.
The [github.com/golang-jwt/jwt](https://github.com/golang-jwt/jwt) project is a drop-in replacement, but supports only the latest 2 Go versions.
So for JWT middleware users Go 1.15+ is required. For detailed information please read [#1940](https://github.com/labstack/echo/discussions/)
To change the library imports in all .go files in your project replace all occurrences of `dgrijalva/jwt-go` with `golang-jwt/jwt`.
For Linux CLI you can use:
```bash
find -type f -name "*.go" -exec sed -i "s/dgrijalva\/jwt-go/golang-jwt\/jwt/g" {} \;
go mod tidy
```
**Fixes**
* Change JWT library to `github.com/golang-jwt/jwt` [#1946](https://github.com/labstack/echo/pull/1946)
## v4.4.0 - 2021-07-12
**Fixes**
* Split HeaderXForwardedFor header only by comma [#1878](https://github.com/labstack/echo/pull/1878)
* Fix Timeout middleware Context propagation [#1910](https://github.com/labstack/echo/pull/1910)
**Enhancements**
* Bind data using headers as source [#1866](https://github.com/labstack/echo/pull/1866)
* Adds JWTConfig.ParseTokenFunc to JWT middleware to allow different libraries implementing JWT parsing. [#1887](https://github.com/labstack/echo/pull/1887)
* Adding tests for Echo#Host [#1895](https://github.com/labstack/echo/pull/1895)
* Adds RequestIDHandler function to RequestID middleware [#1898](https://github.com/labstack/echo/pull/1898)
* Allow for custom JSON encoding implementations [#1880](https://github.com/labstack/echo/pull/1880)
## v4.3.0 - 2021-05-08
**Important notes**
* Route matching has improvements for following cases:
1. Correctly match routes with parameter part as last part of route (with trailing backslash)
2. Considering handlers when resolving routes and search for matching http method handler
* Echo minimal Go version is now 1.13.
**Fixes**
* When url ends with slash first param route is the match [#1804](https://github.com/labstack/echo/pull/1812)
* Router should check if node is suitable as matching route by path+method and if not then continue search in tree [#1808](https://github.com/labstack/echo/issues/1808)
* Fix timeout middleware not writing response correctly when handler panics [#1864](https://github.com/labstack/echo/pull/1864)
* Fix binder not working with embedded pointer structs [#1861](https://github.com/labstack/echo/pull/1861)
* Add Go 1.16 to CI and drop 1.12 specific code [#1850](https://github.com/labstack/echo/pull/1850)
**Enhancements**
* Make KeyFunc public in JWT middleware [#1756](https://github.com/labstack/echo/pull/1756)
* Add support for optional filesystem to the static middleware [#1797](https://github.com/labstack/echo/pull/1797)
* Add a custom error handler to key-auth middleware [#1847](https://github.com/labstack/echo/pull/1847)
* Allow JWT token to be looked up from multiple sources [#1845](https://github.com/labstack/echo/pull/1845)
## 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)

## v4.2.1 - 2021-03-08
**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.

* Apply go fmt (#1788, Le0tk0k)
* Uses strings.Equalfold (#1790, rkilingr)
* Improve code quality (#1792, withshubh)

## v4.2.0 - 2021-02-11
**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.
