### Features

## 2.1.0 (12/19/2018)
* **BREAKING:** Removed `stdoutStream` and `stderrStream` options.
* **NEW:** Added `logHandler` option which takes a `console`-like object to send logs through. (#11)

## 2.0.1 (12/7/2018)
* Fix console logging pointing to global `console` instead of custom console instance for streaming. (@sh1n1chi8acker - #10)
* Update mocha to v5.2.0
* Added `package-lock.json` to .gitignore as it's not needed for this module.

## 2.0.0 (7/15/2018)
The new major release for lambda-log which contains many new extensibility features and a handful of new usability features. There are a few breaking changes from version 1.4.0 to keep in mind when migrating. All breaking changes will be noted in the changelog below:

#### Internal/Module Changes
* Moved `LambdaLog` class out of `index.js` into `lib/LambdaLog.js` for organization purposes.
* **NEW:** Utilize `console` module (native Node) instead of the global `console` object for logging. This allows more control of where logs are redirected to for custom advanced integrations.
* **NEW:** Log messages are now an instance of the `LogMessage` class which allows custom methods and better control over log messages.

#### LambdaLog Class/Configuration
* **NEW:** Added ability to configure the logger via the constructor (#3).
* **NEW:** Added ability to configure the log levels and methods via the constructor.
* **NEW:** Added `stdoutStream` and `stderrStream` configuration options to configure the desired output of log messages. By default it redirects to `process.stdout` and `process.stderr`.
* **NEW:** Added `dynamicMeta` configuration option which will allow dynamic metadata to be added to each log on creation.
* **NEW:** Added `replacer` configuration option for `JSON.stringify`.
* **BREAKING:** Static method `isError()` has been moved to the `LogMessage` class and is no longer accessible in the `LambdaLog` class.

#### Logging Functions
* **NEW:** All log functions now accept an array of tags to append to a log.
* **FIX:** Metadata passed into a log function will now be wrapped in a plain object if the provided value is not an object.
* **BREAKING:** All log functions now return an instance of `LogMessage` instead of a plain log object which allows directly calling additional methods of `LogMessage` (chaining). See documentation for more information.

#### Events
* **BREAKING:** The `log` event now provides an instance of `LogMessage` instead of a plain object.

#### Misc.
* Updated tests.
* Updated documentation/readme.
