## [3.9.0] - [TBD]
### Added
- support `isolatedModules` and `preserveValueImports` compilation scenarios [#305](https://github.com/eleith/emailjs/pull/305)

### Fixed
- support `typescript@3.8.3` [#307](https://github.com/eleith/emailjs/issues/307)
	- the types change in `v3.8.0` for `Client#send` & `Client#sendAsync` unintentionally raised the minimum `typescript` requirement. fixing this involved weakening the types for those functions, which may require modifying your code. this change will be reverted for `v4.0.0`.

### Added
