+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),

 ## 1.0.0 - 2019-03-28
+
 * Benchee 0.99 & 1.0.0 support
 * BREAKING: data structures changed, no more `run_times`/`memory_usages`/`run_time_statitics`/`memory_usage_statistics` - it's all in `run_time_data`/`memory_usage_data` now under the keys `samples`/`statistics` to mirror the original benchee data structure.

 Formats a benchee benchmarking suite to a JSON representation and can also write it to disk. Actively used in [benchee_html](https://github.com/PragTob/benchee_html) to generate JSON, and embed it into the JavaScript to give the JS access to the benchmarking results for graphing purposes.
