+### Breaking changes
+
+No breaking changes have been introduced in this release.
+
+### Added
+
+- **Tag-based distrubuted configuration management**  
+  Only a subset of Kong entities sharing a (set of) tag can now be exported,
+  deleted, diffed or synced.
+  decK can now manage your Kong's configuration in a distributed manner,
+  whereby you can split Kong's configuration by team and each team can manage
+  it's own configuration. Use `select-tag` feature in all the commands and
+  config file for this purpose.
+  [#17](https://github.com/hbagdi/deck/pull/17)
+- **Read/write state from stdout/stdin**
+  Config file can now be read in from standard-input and written out to
+  standard-output.
+  [#10](https://github.com/hbagdi/deck/pull/10),
+  [#11](https://github.com/hbagdi/deck/pull/11)  
+  Thanks to [@matthewbednarski](https://github.com/matthewbednarski) for the contribution.
+- **Automated defaults**  
+  No need to specify default values for all core Kong entities,
+  further simplifying your Kong's configuration.
+  Default values for plugin configuration still need to be defined, this is on
+  the roadmap.
+  [b448d4f](https://github.com/hbagdi/deck/commit/b448d4f)
+- Add support for new properties in Upstream entity in Kong.
+  [080200d](https://github.com/hbagdi/deck/commit/080200d)
+- Empty plugins and other Kong entities are not populated in the config file
+  as empty arrays to keep the file concise and clean.
+  [ae38f1b](https://github.com/hbagdi/deck/commit/ae38f1b)
+
+### Fixed
+
+- Empty arrays in plugin configs are not treated as nil anymore.
+  [#9](https://github.com/hbagdi/deck/pull/9)
+- Correctly sync plugins which are out of sync. Protocols field
+  in plugins can be confused with protocols field in routes in Kong
+  [#6](https://github.com/hbagdi/deck/pull/6)  
+  Thanks to [@davidcv5](https://github.com/davidcv5) for the contribution.
+- Throw an error if an object is not marshalled into YAML correctly.
+- Correctly create service-level plugins for Kong >= 1.1
+  [#16](https://github.com/hbagdi/deck/pull/16)  
+
+### Misc
+
+- `go-kong` has been bumped up to v0.4.1.
