## 0.3.0.0 — May 5, 2019

* [#77](https://github.com/co-log/co-log/issues/77):
  **Important:** Use `chronos` time formatter. This is a breaking change because
  default field map in `RichMessage` now contains different type representing
  time. If you use your custom formatter for time, you should change it.
  Othwerwise no observable differences in the library API usage will be noticed.
* [#103](https://github.com/co-log/co-log/issues/103):
  **Breaking change:** make `Message` data type polymorhic over the type of severity.

  **Migration guide:** this change is done in backwards-compatible way. If you
  use any fields of the `Message` data type, you should rename them according to
  the following scheme:
  ```haskell
  messageSeverity -> msgSeverity
  messageStack    -> msgStack
  messageText     -> msgText
  ```
* Export more formatting functions to make implementation of custom formatters easier.
* [#96](https://github.com/co-log/co-log/issues/96):
  Add `simpleMessageAction` and `richMessageAction` to work with `Message`s.
* Use `co-log-core` of version `0.2.0.0`.

## 0.2.0 — Nov 15, 2018

* [#45](https://github.com/co-log/co-log/issues/45):
  Introduce approach for concurrent log writing.
* [#46](https://github.com/co-log/co-log/issues/46):
  Moves `logStringStdout`, `logStringStderr`, `logStringHandle`,
  `withLogStringFile` from `Colog.Actions` to `Colog.Core.IO`
* [#77](https://github.com/co-log/co-log/issues/77):
  Remove `relude` from dependencies.
  Add HLint check to Travis CI.
* [#64](https://github.com/co-log/co-log/issues/64):
  Introduce basic benchmarks.
* [#20](https://github.com/co-log/co-log/issues/20):
