# Change Log
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/) 
and this project adheres to [Semantic Versioning](http://semver.org/).

## [0.4.0] - 2017-09-04
### Changed
- Concurrent.timeout function now accepts both error message and callback
- Slf4j now substitutes placeholders with everything, including errors.
Placeholders are filled with short representations, off-placeholder 
parameters are using long representations, so in most occasions 
behavior hasn't changed. See README.md for clarification.
- Slf4j now uses custom `.toString()` method for representations (if it 
is present)
- Slf4j now demands Logger only in the last moment, allowing to 
instantiate default context and Slf4j itself without `global.Logger`
being present.

No breaking changes should be introduced by this release, however, 
too much of internals have been altered for a patch release.
