`json.Marshal` and `json.Unmarshal` receive `interface{}` value and they perform type determination dynamically to process.
In normal case, you need to use the `reflect` library to determine the type dynamically, but since `reflect.Type` is defined as `interface`, when you call the method of `reflect.Type`, The reflect's argument is escaped.
Therefore, the arguments for `Marshal` and `Unmarshal` are always escape to the heap.
Therefore, the arguments for `Marshal` and `Unmarshal` are always escaped to the heap.
However, `go-json` can use the feature of `reflect.Type` while avoiding escaping.
`reflect.Type` is defined as `interface`, but in reality `reflect.Type` is implemented only by the structure `rtype` defined in the `reflect` package.

# Changelog
## v4.10.2 - 2023-02-22
**Security**
* `filepath.Clean` behaviour has changed in Go 1.20 - adapt to it [#2406](https://github.com/labstack/echo/pull/2406)
* Add `middleware.CORSConfig.UnsafeWildcardOriginWithAllowCredentials` to make UNSAFE usages of wildcard origin + allow cretentials less likely [#2405](https://github.com/labstack/echo/pull/2405)
**Enhancements**
* Add more HTTP error values [#2277](https://github.com/labstack/echo/pull/2277)
## v4.10.1 - 2023-02-19
**Security**
* Upgrade deps due to the latest golang.org/x/net vulnerability [#2402](https://github.com/labstack/echo/pull/2402)
**Enhancements**
* Add new JWT repository to the README [#2377](https://github.com/labstack/echo/pull/2377)
* Return an empty string for ctx.path if there is no registered path [#2385](https://github.com/labstack/echo/pull/2385)
* Add context timeout middleware [#2380](https://github.com/labstack/echo/pull/2380)
* Update link to jaegertracing [#2394](https://github.com/labstack/echo/pull/2394)
## v4.10.0 - 2022-12-27
**Security**
* We are deprecating JWT middleware in this repository. Please use https://github.com/labstack/echo-jwt instead.
JWT middleware is moved to separate repository to allow us to bump/upgrade version of JWT implementation (`github.com/golang-jwt/jwt`) we are using
which we can not do in Echo core because this would break backwards compatibility guarantees we try to maintain.
* This minor version bumps minimum Go version to 1.17 (from 1.16) due `golang.org/x/` packages we depend on. There are
several vulnerabilities fixed in these libraries.
Echo still tries to support last 4 Go versions but there are occasions we can not guarantee this promise.
**Enhancements**
* Bump x/text to 0.3.8 [#2305](https://github.com/labstack/echo/pull/2305)
* Bump dependencies and add notes about Go releases we support [#2336](https://github.com/labstack/echo/pull/2336)
* Add helper interface for ProxyBalancer interface [#2316](https://github.com/labstack/echo/pull/2316)
* Expose `middleware.CreateExtractors` function so we can use it from echo-contrib repository [#2338](https://github.com/labstack/echo/pull/2338)
* Refactor func(Context) error to HandlerFunc [#2315](https://github.com/labstack/echo/pull/2315)
* Improve function comments [#2329](https://github.com/labstack/echo/pull/2329)
* Add new method HTTPError.WithInternal [#2340](https://github.com/labstack/echo/pull/2340)
* Replace io/ioutil package usages [#2342](https://github.com/labstack/echo/pull/2342)
* Add staticcheck to CI flow [#2343](https://github.com/labstack/echo/pull/2343)
* Replace relative path determination from proprietary to std [#2345](https://github.com/labstack/echo/pull/2345)
* Remove square brackets from ipv6 addresses in XFF (X-Forwarded-For header) [#2182](https://github.com/labstack/echo/pull/2182)
* Add testcases for some BodyLimit middleware configuration options [#2350](https://github.com/labstack/echo/pull/2350)
* Additional configuration options for RequestLogger and Logger middleware [#2341](https://github.com/labstack/echo/pull/2341)
* Add route to request log [#2162](https://github.com/labstack/echo/pull/2162)
* GitHub Workflows security hardening [#2358](https://github.com/labstack/echo/pull/2358)
* Add govulncheck to CI and bump dependencies [#2362](https://github.com/labstack/echo/pull/2362)
* Fix rate limiter docs [#2366](https://github.com/labstack/echo/pull/2366)
* Refactor how `e.Routes()` work and introduce `e.OnAddRouteHandler` callback [#2337](https://github.com/labstack/echo/pull/2337)

## Supported Go versions
Latest version of Echo supports last four Go major [releases](https://go.dev/doc/devel/release) and might work with older versions.
Latest version of Echo supports last four Go major [releases](https://go.dev/doc/devel/release) and might work with
older versions.
As of version 4.0.0, Echo is available as a [Go module](https://github.com/golang/go/wiki/Modules).
Therefore a Go version capable of understanding /vN suffixed imports is required:
Any of these versions will allow you to import Echo as `github.com/labstack/echo/v4` which is the recommended
way of using Echo going forward.

Care should be taken when parsing and interpreting HTML, whether full documents

regard to untrusted inputs.
This package provides both a tokenizer and a parser. Only the parser constructs
a DOM according to the HTML specification, resolving malformed and misplaced
tags where appropriate. The tokenizer simply tokenizes the HTML presented to it,
and as such does not resolve issues that may exist in the processed HTML,
producing a literal interpretation of the input.
If your use case requires semantically well-formed HTML, as defined by the
WHATWG specifiction, the parser should be used rather than the tokenizer.
