Fixed bugs related to the new major MATRX release.

• Fixed bug where the frontend broke when a message did not have a string as message content.

V2.0.0

The second official release of MATRX. The major feature for this release is a robust chat!

Unfortunatly the robust chat required some structural changes which means V2.0.0 is not fully backwards-compatible, thus needing extra caution when upgrading from MATRX v1.1.x to MATRX v.2.0.0. Especially if you use a custom or customized frontend. To make this as smooth as possible, a tutorial has been added to the MATRX website which can be found here.

Features

• Chats that work robustly! Overhaul of the MATRX API calls that fetch messages (/get_latest_state_and_messages and /get_messages) to facilitate more robust chat functionality in frontends.
• Updated the MATRX visualizer to work with the new API usage for a robust chat.
• God agents can now see all other chats (but not respond)
• Fixed bug where API tries to fetch states from non-existing agents
• Human agents can now open a private chatroom with any other agent, or teams of which they are part.

Dissemination

• Wrote an upgrade tutorial for upgrading from MATRX v1.1.x to V2.0.0: https://matrx-software.com/docs/upgrading-matrx/upgrading-matrx-v1-x-x-to-v-2-0-0/

v1.1.2

Description

Patches for several bugs in v1.1.1.

Release notes

Minor features:

• Every AgentBrain had a package private attribute self._state, this is now a public attribute: self.state.

Bugs fixed:

• Formatted the code of HumanAgentBrain to the Python standards (only styling, no refactors).
• Fixed a bug where the State object of an AgentBrain always said a key was present, even when it was not (#195).
• Fixed a bug where a utility/helper function, utils._flatten_dict, of MATRX was private instead of package private, causing MATRX to crash when calling this method (#218).
• Fixed a bug that caused the Navigator to raise an (inappropriate) exception when a route to some waypoint could not be found because it was blocked. Now raises a more informative RunTimeWarning instead (#219).

v1.1.1

Description

Patches for several bugs in v1.1.0 and some minor tweaks.

Release notes

Minor features:

• Edited the Flask dependency to include all releases above v1.1.1 (in response to #179)
• Simplied the State update when memory is not needed, both to speed up things and make it less bug-sensitive.

Website:

• Added a tutorial on the context menus

Bugs fixed:

• Context menu not working for God view
• Context menu only opened when right clicking on agent
• New agent State object wasn't fully implemented for the HumanAgent

v1.1.0

Description

The first minor release of MATRX.

This update includes working context menus that allows a human agent to control its agent (and others) with a right-click mouse menu that is context sensitive.

This update also improves the state object of agents. Instead of just being a description of what an agent perceived, it is now fully searchable by property instead relying solely on the object IDs.

Finally, the documentation has been updated and we are one step closer to 100% coverage.

Release notes

Major features:

• Simplified usage of an agent's state (#156)
• Context sensitive context menus to control and direct agents (#154)
• Inclusion of a BW4T world design under matrx.cases (#78 and #164)

Minor features:

• Rooms now have a name linked to them, this includes all objects that make that room.
• There is a new helper method to get all locations inside a room.
• Added some attributes to HumanAgentBrain for defining the pickup/drop/open door behaviours.
• Allowed AreaTile to have custom properties.
• Renamed UseCaseGoal to WorldGoal.
• The WorldBuilder prints its progress when creating the world.
• Several checks for an object's location, size and shape.
• Removed console output clutter from API and Flask.
• Improved MATRX' message handling between agents.
• A custom API call to reduce perceived states from the server side with the option to filter based on property values (#177).

• MATRX installation tutorial (#85)
• MATRX quick start tutorial (#86)
