+## 1.0.0 - 2019-03-18
+### Added
+- Final updates to the Abaco Autoscaler in preparation for its release.
+- Added "actor queues" feature to allow actors to be registered into a specific queue so that dedicated computing resources can be provided for specific groups of actors; updates to the controlers, spawner and health agents were made to support this feature.
+- Added a "description" field on nonce objects to ease user management of nonces.
+- Added a new "image classifier" sample, `abacosamples/binary_message_classifier`, that uses a pre-trained image classifier algorithm based on tensorflow to classify an image sent as a binary message.  
+
+### Changed
+- Aliases are now restricted to a whilelist of characters to prevent issues with the use of non-URL safe characters. 
+- Several modules were changed to improve handling of errors such as connection issues with RabbitMQ or socket level errors generated by the Docker daemon. 
+
+### Removed
+- No change.

 ## 0.12.0 - 2019-01-21
