## 0.18.0

This release removes the dependency on `stud` and vendors in a forked version
of `Stud::Buffer`. This improves the buffering behavior of LogStashLogger by
flushing all log messages in a background thread by default. This eliminates
blocking behavior and exceptions bubbling up to the main process.

- Fixes `Attempt to unlock a mutex which is not locked (ThreadError)`.

## 0.16.0

## 0.5.0
- Support for tagged logging. The interface was extracted from `ActiveSupport::TaggedLogging`
and outputs to the `tags` key.

- Support for using SSL for TCP connections.
- Support for configuring logger to write to STDOUT.

- Output event timestamp consistently even if `Time#to_json` is overridden.
- Major refactoring which will lead the way to support other log types.
