+## 0.6.3
+
+* Messages returned by `Request.change()` and `Response.change()` are marked
+  read whenever the original message is read, and vice-versa. This means that
+  it's possible to read a message on which `change()` has been called and to
+  call `change()` on a message more than once, as long as `read()` is called on
+  only one of those messages.
+
+## 0.6.2+1
+
+* Support `http_parser` 1.0.0.
+
+## 0.6.2
+
+* Added a `body` named argument to `change` method on `Request` and `Response`.
+
+## 0.6.1+3
+
+* Updated minimum SDK to `1.9.0`.
+
+* Allow an empty `url` parameter to be passed in to `new Request()`. This fits
+  the stated semantics of the class, and should not have been forbidden.
+
+## 0.6.1+2
+
+* `logRequests` outputs a better message a request has a query string.
+
+## 0.6.1+1
+
+* Don't throw a bogus exception for `null` responses.
+
+## 0.6.1
+
+* `shelf_io` now takes a `"shelf.io.buffer_output"` `Response.context` parameter
+  that controls `HttpResponse.bufferOutput`.
+
+* Fixed spelling errors in README and code comments.
+
+## 0.6.0
+
+**Breaking change:** The semantics of `Request.scriptName` and
+[`Request.url`][url] have been overhauled, and the former has been renamed to
+[`Request.handlerPath`][handlerPath]. `handlerPath` is now the root-relative URL
+path to the current handler, while `url`'s path is the relative path from the
+current handler to the requested. The new semantics are easier to describe and
+to understand.
+
+[url]: http://www.dartdocs.org/documentation/shelf/latest/index.html#shelf/shelf.Request@id_url
+[handlerPath]: http://www.dartdocs.org/documentation/shelf/latest/index.html#shelf/shelf.Request@id_handlerPath
+
+Practically speaking, the main difference is that the `/` at the beginning of
+`url`'s path has been moved to the end of `handlerPath`. This makes `url`'s path
+easier to parse using the `path` package.
+
+[`Request.change`][change]'s handling of `handlerPath` and `url` has also
+changed. Instead of taking both parameters separately and requiring that the
+user manually maintain all the associated guarantees, it now takes a single
+`path` parameter. This parameter is the relative path from the current
+`handlerPath` to the next one, and sets both `handlerPath` and `url` on the new
+`Request` accordingly.

+  top-leveled.
+
+* Add more detail to the README about handlers, middleware, and the rules for
