# Changelog

## v4.14.0 - 2025-12-xx
## v4.14.0 - 2025-12-11

`middleware.Logger` has been deprecated. For request logging, use `middleware.RequestLogger` or
`middleware.RequestLoggerWithConfig`.

`middleware.RequestLogger` replaces `middleware.Logger`, offering comparable configuration while relying on the
Go standard library’s new `slog` logger.

The previous default output format was JSON. The new default follows the standard `slog` logger settings.
To continue emitting request logs in JSON, configure `slog` accordingly:
```go
slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
e.Use(middleware.RequestLogger())
```


**Security**

* Logger middleware: escape string values when logger format looks like JSON
* Logger middleware json string escaping and deprecation by @aldas in https://github.com/labstack/echo/pull/2849



**Enhancements**

* Add `middleware.RequestLogger` function to replace `middleware.Logger`. `middleware.RequestLogger` uses default slog logger.
Default slog logger output can be configured to JSON format like that:
```go
slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
e.Use(middleware.RequestLogger())
```
* Deprecate `middleware.Logger` function and point users to `middleware.RequestLogger` and `middleware.RequestLoggerWithConfig`
* Update deps by @aldas in https://github.com/labstack/echo/pull/2807
* refactor to use reflect.TypeFor by @cuiweixie in https://github.com/labstack/echo/pull/2812
* Use Go 1.25 in CI by @aldas in https://github.com/labstack/echo/pull/2810
* Modernize context.go by replacing interface{} with any by @vishr in https://github.com/labstack/echo/pull/2822
* Fix typo in SetParamValues comment by @vishr in https://github.com/labstack/echo/pull/2828
* Fix typo in ContextTimeout middleware comment by @vishr in https://github.com/labstack/echo/pull/2827
* Improve BasicAuth middleware: use strings.Cut and RFC compliance by @vishr in https://github.com/labstack/echo/pull/2825
