- `iris.DirListRichOptions` to pass on `iris.DirListRich` method.
-- `iris.ErrGzipNotSupported` to export the `context.ErrGzipNotSupported` when trying to write gzip but client does not support.
-- `iris.GzipReader` middleware to decode gzip requests on next read actions.
+- `iris.Compress` and `iris.CompressReader` middleware to compress responses and decode compressed request data respectfully.
- `iris.B, KB, MB, GB, TB, PB, EB` for byte units.
- `TLSNoRedirect` to disable automatic "http://" to "https://" redirections (see below)
- `CookieAllowReclaim`, `CookieAllowSubdomains`, `CookieSameSite`, `CookieSecure` and `CookieEncoding` to bring previously sessions-only features to all cookies in the request.
New Context Methods:
+- `Context.Compress(bool) error` and `Context.CompressReader(bool) error`
- `Context.Clone() Context` returns a copy of the Context.
- `Context.IsCanceled() bool` reports whether the request has been canceled by the client.
- `Context.IsSSL() bool` reports whether the request is under HTTPS SSL (New `Configuration.SSLProxyHeaders` and `HostProxyHeaders` fields too).

- `Context.GetDomain() string` returns the domain.

+- `ctx.ClientSupportsGzip() bool` replaced with `ctx.ClientSupportsEncoding("gzip", "br" ...) bool`.
+- `ctx.GzipResponseWriter()` is **removed**.
- `Party.HandleDir` now returns a list of `[]*Route` (GET and HEAD) instead of GET only.
- `Context.OnClose` and `Context.OnCloseConnection` now both accept an `iris.Handler` instead of a simple `func()` as their callback.
- `Context.StreamWriter(writer func(w io.Writer) bool)` changed to `StreamWriter(writer func(w io.Writer) error) error` and it's now the `Context.Request().Context().Done()` channel that is used to receive any close connection/manual cancel signals, instead of the deprecated `ResponseWriter().CloseNotify()` one. Same for the `Context.OnClose` and `Context.OnCloseConnection` methods.
-- Fixed handler's error response not be respected when response recorder or gzip writer was used instead of the common writer. Fixes [#1531](https://github.com/kataras/iris/issues/1531). It contains a **BREAKING CHANGE** of: the new `Configuration.ResetOnFireErrorCode` field should be set **to true** in order to behave as it used before this update (to reset the contents on recorder or gzip writer).

- `Context.String()` (rarely used by end-developers) it does not return a unique string anymore, to achieve the old representation you must call the new `Context.SetID` method first.
- `iris.CookieEncode` and `CookieDecode` are replaced with the `iris.CookieEncoding`.
- `sessions#Config.Encode` and `Decode` are removed in favor of (the existing) `Encoding` field.
- `versioning.GetVersion` now returns an empty string if version wasn't found.
- Change the MIME type of `Javascript .js` and `JSONP` as the HTML specification now recommends to `"text/javascript"` instead of the obselete `"application/javascript"`. This change was pushed to the `Go` language itself as well. See .
-- Remove the last input argument of `enableGzipCompression` in `Context.ServeContent`, `ServeFile` methods. This was deprecated a few versions ago. A middleware (`app.Use(iris.Gzip)`) or a prior call to `Context.Gzip(true)` will enable gzip compression. Also these two methods and `Context.SendFile` one now support `Content-Range` and `Accept-Ranges` correctly out of the box (`net/http` had a bug, which is now fixed).

+There is a breaking change on the type alias of `iris.Context` which now points to the `*context.Context` instead of the `context.Context` interface. The **interface has been removed** and the ability to **override** the Context **is not** available any more. When we added the ability from end-developers to override the Context years ago, we have never imagine that we will ever had such a featured Context with more than 4000 lines of code. As of Iris 2020, it is difficult and un-productive from an end-developer to override the Iris Context, and as far as we know, nobody uses this feature anymore because of that exact reason. Beside the overriding feature support end, if you still use the `context.Context` instead of `iris.Context`, it's the time to do it: please find-and-replace to `iris.Context` as wikis, book and all examples shows for the past 3 years. For the 99.9% of the users there is no a single breaking change, you already using `iris.Context` so you are in the "safe zone".
