+## 0.4.0 (2020-10-02)
 * Added `expect.extend` which allows projects to register their own, opinionated expectations that integrates into `expect`. ([#142](https://github.com/Roblox/testez/pull/142))
   * Modeled after [jest's implementation](https://jestjs.io/docs/en/expect#expectextendmatchers).
   * Matchers are functions that should return an object with with two keys, boolean `pass` and a string `message`

 * Change the way errors are collected to call tostring on them before further processing.
   * Luau allows non-string errors, but not concatenating non-strings or passing non-strings to `debug.traceback` as a message, so TestRunner needs to do that step. This is a temporary fix as the better solution would be to retain the error in object form for as long as possible to give the reporter more to work with.
   * This also makes a slight change to what's in the traceback to eliminate the unnecessary line mentioning the error collection function.
+* Fix debugging of tests in Studio
 
 ## 0.3.3 (2020-09-25)
 * Remove the lifecycle hooks from the session tree. This prevents the `[?]` spam from the reporter not recognizing these nodes.
