 ### Bug Fixes
 
-* semantic release fixes ([3769769](https://github.com/ZeeCoder/use-resize-observer/commit/3769769dd550e96b8497c1ccebcffc3b30d2eb7a))
-* Using package.json file attr instead of gitignore ([c58f34e](https://github.com/ZeeCoder/use-resize-observer/commit/c58f34e11b68ef9622a6b2528da8ee68a9685211))
-
+- Only instantiating a ResizeObserver instance if there's actually something to
+  observe. This for example means that if you pass in `null` or undefined as the
+  ref, or if neither the default ref or RefCallback returned from the hook are
+  in use, then no ResizeObserver instance will get created until there's an
+  actual element to observe. Resolves: #42
+- Fixed an error where in certain edge cases the hook tried to set state when
+  its host component already unmounted.
 
-* Added Semantic Release ([55f6368](https://github.com/ZeeCoder/use-resize-observer/commit/55f6368c1b0c3154bfd6ed16e089763de0b0ba47))
+### Features
 
+- The `ref` option now accepts raw elements as well.
 
 ### BREAKING CHANGES
 
-* - The returned ref is now a RefCallback, not a ref object
+- The returned ref is now a RefCallback, not a ref object. Resolves: #43, #45
 - The returned ref will always be the same RefCallback.
   Previously when a custom ref object was passed, it was returned as well from
   the hook as "ref".
-- Compared to 6.2.0-alpha.1 There's no `callbackRef` return value
-  anymore.
+- Compared to 6.2.0-alpha.1 There's no `callbackRef` return value anymore.
+
+### Misc
+
+- Using package.json file attr instead of gitignore ([c58f34e](https://github.com/ZeeCoder/use-resize-observer/commit/c58f34e11b68ef9622a6b2528da8ee68a9685211))
+- Added Semantic Release ([55f6368](https://github.com/ZeeCoder/use-resize-observer/commit/55f6368c1b0c3154bfd6ed16e089763de0b0ba47))
+- Handling custom refs (through options), the default ref and the RefCallback
+  has been greatly refactored internally (into the `useResolvedElement`
+  hook), to handle more edge cases with the way refs are handled.
+- Tests based on react testing library were refactored to make them much simpler
+  and more approachable.
+- Added [contributing guidelines](./CONTRIBUTING.md)
+- Added tests in real browsers with BrowserStack, so that we ensure the lib
+  works all the way back to IE11.
+- Switched to GitHub Actions from Travis, as builds started to freeze. (They've
+  also announced a [limit on OS projects](https://blog.travis-ci.com/2020-11-02-travis-ci-new-billing).)
