Other Improvements:
- [gRPC](https://grpc.io/) features:
- New Router [Wrapper](middleware/grpc).
- New MVC `.Handle(ctrl, mvc.GRPC{...})` option which allows to register gRPC services per-party (without the requirement of a full wrapper) and optionally strict access to gRPC clients only, see the [example here](_examples/mvc/grpc-compatible).
- Improved logging (with `app.Logger().SetLevel("debug")`) for MVC-registered routes.
- New `iris.WithLowercaseRouting` option which forces all routes' paths to be lowercase and converts request paths to their lowercase for matching.
- New `app.Validator { Struct(interface{}) error }` field and `app.Validate` method were added. The `app.Validator = ` can be used to integrate a 3rd-party package such as [go-playground/validator](https://github.com/go-playground/validator). If set-ed then Iris `Context`'s `ReadJSON`, `ReadXML`, `ReadMsgPack`, `ReadYAML`, `ReadForm`, `ReadQuery`, `ReadBody` methods will return the validation error on data validation failures. The [read-json-struct-validation](_examples/http_request/read-json-struct-validation) example was updated.
- A result of <T> can implement the new `hero.PreflightResult` interface which contains a single method of `Preflight(iris.Context) error`. If this method exists on a custom struct value which is returned from a handler then it will fire that `Preflight` first and if not errored then it will cotninue by sending the struct value as JSON(by-default) response body.

- Hero Handlers (and `app.ConfigureContainer().Handle`) do not have to require `iris.Context` just to call `ctx.Next()` anymore, this is done automatically now.
- Improve Remote Address parsing as requested at: https://github.com/kataras/iris/issues/1453. Add `Configuration.RemoteAddrPrivateSubnets` to exclude those addresses when fetched by `Configuration.RemoteAddrHeaders` through `context.RemoteAddr() string`.
- Improve Remote Address parsing as requested at: [#1453](https://github.com/kataras/iris/issues/1453). Add `Configuration.RemoteAddrPrivateSubnets` to exclude those addresses when fetched by `Configuration.RemoteAddrHeaders` through `context.RemoteAddr() string`.
- Fix [#1487](https://github.com/kataras/iris/issues/1487).
- Fix [#1473](https://github.com/kataras/iris/issues/1473).
New Context Methods:
- `context.IsHTTP2() bool` reports whether the protocol version for incoming request was HTTP/2
- `context.IsGRPC() bool` reports whether the request came from a gRPC client
- `context.UpsertCookie(*http.Cookie, cookieOptions ...context.CookieOption)` upserts a cookie, fixes [#1485](https://github.com/kataras/iris/issues/1485) too
- `context.StopWithStatus(int)` stops the handlers chain and writes the status code
- `context.StopWithJSON(int, interface{})` stops the handlers chain, writes the status code and sends a JSON response
