# [3.0.0](https://github.com/blesh/symbol-observable/compare/2.0.3...3.0.0) (2020-11-02)


### Bug Fixes

* **TypeScript:** `Symbol.observable` is now `unique symbol`. ([2ef1476](https://github.com/blesh/symbol-observable/commit/2ef147644cf78538b28c3fd9e66a3b8d569a1978)), closes [#41](https://github.com/blesh/symbol-observable/issues/41)
* **TypeScript:** `Symbol[Symbol.observable]` is no longer incorrectly defined ([fe4301f](https://github.com/blesh/symbol-observable/commit/fe4301f37b54162e1a2db91e79c5b33d652496f1))


### BREAKING CHANGES

* **TypeScript:** Older versions of `@types/node` will clash with this, because `@types/node` incorrectly defined `Symbol.observable` has `symbol` and not `unique symbol`. Update to `@types/node@14.14.6` or higher.

# [2.0.0](https://github.com/blesh/symbol-observable/compare/1.2.0...2.0.0) (2020-09-01)

### Bug Fixes

- Resolve issues in environments with frozen Symbol ([2323882](https://github.com/blesh/symbol-observable/commit/23238827ea234188b11774f43afcb5c8deeb278e))

**BREAKING CHANGE**: This moves to using `Symbol.for` to create the symbol instance. It's _possible_ that some runtimes that support `Symbol` do not support `Symbol.for`. Therefor, I'm marking this as a breaking change. If you find that you hit this issue, please report it. You can work around it by polyfilling `Symbol.for`.
