## [2.2.0] - 2020-02-08
### SPEC Changes
- `rack.session` request environment entry must respond to `to_hash` and return unfrozen Hash. ([@jeremyevans](https://github.com/jeremyevans))
- Request environment cannot be frozen. ([@jeremyevans](https://github.com/jeremyevans))
- CGI values in the request environment with non-ASCII characters must use ASCII-8BIT encoding. ([@jeremyevans](https://github.com/jeremyevans))
- Improve SPEC/lint relating to SERVER_NAME, SERVER_PORT and HTTP_HOST. ([#1561](https://github.com/rack/rack/pull/1561), [@ioquatix](https://github.com/ioquatix))
### Added
- `rackup` supports multiple `-r` options and will require all arguments. ([@jeremyevans](https://github.com/jeremyevans))

- `Multipart::UploadedFile` supports keyword arguments `:path`, `:content_type`, and `:binary` in addition to positional arguments. ([@jeremyevans](https://github.com/jeremyevans))
- `Static` supports a `:cascade` option for calling the app if there is no matching file. ([@jeremyevans](https://github.com/jeremyevans))

- Convenient cache and content type methods for `Rack::Response`. ([#1555](https://github.com/rack/rack/pull/1555), [@ioquatix](https://github.com/ioquatix))
### Changed
- `Request#params` no longer rescues EOFError. ([@jeremyevans](https://github.com/jeremyevans))
- `Directory` uses a streaming approach, significantly improving time to first byte for large directories. ([@jeremyevans](https://github.com/jeremyevans))
- `Directory` no longer includes a Parent directory link in the root directory index. ([@jeremyevans](https://github.com/jeremyevans))
- `QueryParser#parse_nested_query` uses original backtrace when reraising exception with new class. ([@jeremyevans](https://github.com/jeremyevans))

- `Etag` will continue sending ETag even if the response should not be cached. ([@henm](https://github.com/henm))
- `Request#host_with_port` no longer includes a colon for a missing or empty port. ([@AlexWayfer](https://github.com/AlexWayfer))
- All handlers uses keywords arguments instead of an options hash argument. ([@ioquatix](https://github.com/ioquatix))
- `Files` handling of range requests no longer return a body that supports `to_path`, to ensure range requests are handled correctly. ([@jeremyevans](https://github.com/jeremyevans))

- `Request#ssl?` is true for the `wss` scheme (secure websockets). ([@jeremyevans](https://github.com/jeremyevans))
- `Rack::HeaderHash` is memoized by default. ([#1549](https://github.com/rack/rack/pull/1549), [@ioquatix](https://github.com/ioquatix))

([#1561](https://github.com/rack/rack/pull/1561), [@ioquatix](https://github.com/ioquatix))
- `Rack::Builder` parsing options on first `#\` line is deprecated. ([#1574](https://github.com/rack/rack/pull/1574), [@ioquatix](https://github.com/ioquatix))
### Removed
- `Directory#path` as it was not used and always returned nil. ([@jeremyevans](https://github.com/jeremyevans))

- `Directory` correctly escapes paths in links. ([@yous](https://github.com/yous))
- `Request#delete_cookie` and related `Utils` methods handle `:domain` and `:path` options in same call. ([@jeremyevans](https://github.com/jeremyevans))
- `Request#delete_cookie` and related `Utils` methods do an exact match on `:domain` and `:path` options. ([@jeremyevans](https://github.com/jeremyevans))
- `Static` no longer adds headers when a gzipped file request has a 304 response. ([@chooh](https://github.com/chooh))
- `ContentLength` sets `Content-Length` response header even for bodies not responding to `to_ary`. ([@jeremyevans](https://github.com/jeremyevans))

* First-party "SameSite" cookies. Browsers omit SameSite cookies
from third-party requests, closing the door on many CSRF attacks.
Pass `same_site: true` (or `:strict`) to enable:
response.set_cookie 'foo', value: 'bar', same_site: true
or `same_site: :lax` to use Lax enforcement:
response.set_cookie 'foo', value: 'bar', same_site: :lax
Based on version 7 of the Same-site Cookies internet draft:

== Future specification changes
PLEASE NOTE: In versions of Rack LATER than 0.4, the following
changes will be commited to the Rack specification:
* 1xx, 204 and 304 status codes MUST not contain a Content-Type.
* A valid Content-Length header MUST be provided for non 1xx, 204 and 304
responses with a Transfer-Encoding of "identity" (default).
The Content-Length MUST be the same as the sum of the byte-sizes of
the chunks.
* The REQUEST_METHOD may be any HTTP token.
Internal Rack modules have been updated to follow this behavior, but
the Rack 0.4 Lint does NOT check it yet for compatibility reasons.
Please update your libraries accordingly.

Rack provides a minimal, modular and adaptable interface for developing
web applications in Ruby. By wrapping HTTP requests and responses in
the simplest way possible, it unifies and distills the API for web
servers, web frameworks, and software in between (the so-called
middleware) into a single method call.
