## 4.2.0

  - Defaults to `false`. This will default to `true` in the next major release

## 4.1.2
14 May 2015

  - `koa-router` no longer treats `params` as an array

## 4.1.1
7 May 2015

- Added io.js v2.0.x to CI build
- Fixed bug in request id middleware
  - It was implemented incorrectly but tests were passing

## 4.1.0
6 May 2015

- Added `koa-x-request-id` middleware for adding request ids to distinguish between requests and for supporting logging
- Added ability to disable middleware if needed
- Added `app.KF_VERSION` to return the `koa-framework` version


## 4.0.0
2 May 2015

- Changed `app.router` to create `koa-router` instances instead of returning a single instance
  - This adds the benefit of adding namespaced middleware by creating multiple routers


## 3.5.0
19 Mar 2015

- Changed how schema errors are handled
  - The server now sends `res.error` and `res.validationErrors` in the response body
- Added branding assets


## 3.4.1
13 Feb 2015

- Fixed bug where `opt.strict` overrides `additionalProperties`.
- Additionally, `opt` argument in `app.schema` has been deprecated as all its functionality can be provided with the passed schema. It just adds additional complexity.
  - Instead of setting `opt.strict` to `true`, simply pass `additionalProperties` to `false`.
