 - Made observation space flattening optional (on by default). To turn off for an agent, change the `agent_settings.flatten_obs` setting in the config.
 - Added support for SQL INSERT command.
 - Added ability to log each agent's action choices in each step to a JSON file.

+Terminal
+########
+
+The ``Terminal`` provides a generic terminal simulation, by extending the base Service class
+
+Key capabilities
+================
+
+ - Authenticates User connection by maintaining an active User account.
+ - Ensures packets are matched to an existing session
+ - Simulates common Terminal commands
+ - Leverages the Service base class for install/uninstall, status tracking etc.
+
+
+Usage
+=====
+
+ - Install on a node via the ``SoftwareManager`` to start the Terminal
+ - Terminal Clients connect, execute commands and disconnect.
+ - Service runs on SSH port 22 by default.
+
+Implementation
+==============
+
+- Manages SSH commands
+- Ensures User login before sending commands
+- Processes SSH commands
+- Returns results in a  *<TBD>* format.
