## [5.1.2] - 2021-01-31

### Fixed

- Fixed bug in `fromWebSerial` where `AbortController` signal already called and not firing in main function

## [5.1.1] - 2021-01-31

### Changed

- Internal improvements to `toWritableStream` and `fromWebSerial`

### Fixed

- `fromWebSerial` writer Observable now correctly accepts `Uint8Array` instead of `string`

## [5.1.0] - 2021-01-30

### Added

- `fromWebSerial` Observable that allows communication between [Web Serial](https://reillyeon.github.io/serial/) devices
  using RxJS (see [demo](https://rxjs-from-web-serial.stackblitz.io)
  and [source](https://stackblitz.com/edit/rxjs-from-web-serial))

### Fixed

- Correct export path for `length` operator

## [5.0.0] - 2021-01-26

Breaking change in side-effect operators, reverting to earlier code - when tested in isolation they did not cause issues
however when used together issues were caused.

### Added

- `takeUntilSignal` operator that provides the same interface as [takeUntil](https://rxjs.dev/api/operators/takeUntil)
  but uses an [AbortSignal](https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal) as the notifier.
- `tapOnUnSubscribe` operator that is called on each source unsubscription.

### Fixed

- `tapOnFirstEmit` & `tapOnSubscribe` now correctly emit the source as the return Observable, no longer return the
  source value inside the callback function.
- `tapIf` no longer turns the source, instead source is always tapped but callback function is still only run if the
  predicate method passes

## [4.4.1] - 2021-01-26

### Fixed

- `fromEventSource` returns `ErrorEvent` instead of `error.message` which was undefined

## [4.4.0] - 2021-01-26

### Added

- `fromEventSource` Observable that emits values from a
  passed [EventSource](https://developer.mozilla.org/en-US/docs/Web/API/EventSource)

## [4.3.1] - 2021-01-25

### Fixed

- Update to internal build configuration for UMD compile `rxjs` and `rxjs/operators` now correctly set as `rxjs`
  and `rxjs.operators` for globals

### [4.3.0] - 2021-01-25

### Added

- `temperature` operator now also includes [Rankine](https://en.wikipedia.org/wiki/Rankine_scale) conversion

### Changed

- `temperature` operator accepts string or Enum parameters (strings are still fixed to supported temperature types)
- `weight` operator accepts string or Enum parameters (strings are still fixed to supported weight types)
- `length` operator accepts string or Enum parameters (strings are still fixed to supported length types)
- `temperature` & `weight` operators correctly have precision of `2` as default
- Internal refactor of new code and tests

## [4.2.0] - 2021-01-22

### Added

#### Conversion

- `length` operator that accepts `fromLength` and `toLength` properties and modifies the source number using a length
  calculation
  - Example: `length(Lengths.KILOMETERS, Lengths.MILES)` to convert a Kilometer length to Miles
- `temperature` operator that accepts `temperatureFrom` and `temperatureTo` properties and modifies the source number
  using a temperature calculation
  - Example: `temperature(Temperatures.KELVIN, Temperatures.CELSIUS)` to convert from Kelvin to Celsius
- `weight` operator that accepts `fromWeight` and `toWeight` properties and modifies the source number using a weight
  conversion
  - Example: `weight(Weights.GRAMS, Weights.KILOGRAMS)` to convert Grams to Kilograms

#### Color

- `rgbToHex` and `rgbaToHex` which converts RGB/RGBA strings to their Hex colour value
- `hexToRGBA` which converts a Hex string to RGB/RGBA

## [4.1.2] - 2021-01-21

### Changed

- `fromReadableStream` calls `subscriber.complete` and not `subscriber.error` when using `AbortController` by default
  but can accept a parameter to throw as error
- `toWritableStream` internal improvements on how it handles errors.
- `toWritableStream` now accepts `WritableStreamDefaultWriter` object
- `toWritableStream` now accepts `AbordSignal` object to cancel the stream without ending the subscription
- Tests now use property ReadableStream and WritableStream polyfills instead of custom implementation

## [3.1.0] - 2021-01-12

### Added
