🗒️Release notes

This page shows the release notes for all M² platform releases.

All release notes include new feature highlights, breaking changes which need consideration prior to ingesting a new release, a full change list of what's new, any known issues and performance benchmark information.

M² Platform Release v20


Latest Binary Version 20.0.0

Audio: Mic Check

We have introduced a simple and easy to use interface to test microphone functionality and audio quality before engaging in communication.

It detects whether the user has a working microphone, shows if they are loud enough and can loopback the user's speech back at them without anyone else in the world hearing it.

This interface can be presented as part of the event entry process (first time user flow) and can easily be accessed again in the settings or as part of the speak button afterwards.

This feature is meant to ensure clear and reliable voice transmission in the metaverse and ease users into voice chat.

World Object Interactions

Allowing users interact with in-world objects (MML or otherwise).

This feature delivers:

  • Foundational interaction system for MML and non-MML Unreal objects

  • Interaction list (presenting the verbs of an object on a list)

  • Focus camera on objects

  • Object targeting and highlighting

  • Keyboard shortcut support for the interaction list

This enhances on the features documented here: Interaction Advanced Features | MSquared Platform Documentation

M² Platform Release v19.1.1

Hotfixed version to add in some additional fixes for the Live config v1 shutdown as well as address some streaming client issues identified with downstream projects.


Latest binary version 19.1.1

Move.ai Realtime Full Body Motion Capture

The actor can come to Improbable office and start streaming their movement within minutes.

See documentation here Move.ai | MSquared Platform Documentation

Avatars: Faces & Hairstyles

A wider selection of faces and hairstyles have been added to be chosen by users in the Avatar customiser.

Avatars: Adding Attachments

Attachments that can be added to any MML Character (our "Origin M2 Avatar", ingested NFTs or Imported characters) through socketing, using our Web and Unreal Avatar Editors.

  1. Adding appropriately tagged sockets to the default character MML to support Hats (top of head), Glasses (top of face), Back (back), Hands (right and left) on our Origin M2 Avatar.

  2. Providing a way to add and validate appropriate tagged sockets to ingested NFT or imported characters. 3. Resolve edge cases. such as if a random MML is imported with socket attachment points that are not supported. or providing warnings to a user that the model they have chosen doesn't support sockets.

Doing this will enable users to use the Wardrobe to equip characters with objects such as hats, glasses, wings (backslot) and hand held items from their collection.

See documentation here https://docs.msquared.io/tutorials-and-features/avatars/avatar-attachments

Live config v1 shutdown

v19 includes Array support in M2LiveConfig, and the removal of console commands for the old live config system.

For more information on the Live Config system please read https://docs.msquared.io/tutorials-and-features/live-config

M² Platform Release v18


Latest binary version

Self-Serve: Access Controls

Metaverse Owners (and delegates) can manage org perms

  • Org management

    • Permission groups for event runners / content creators / overlaps

    • Restrictions on worlds launchable per user / durations / sizes

See documentation here: https://docs.msquared.io/admins/managing-access

Please note that this feature is available to all projects, regardless of Platform Release version.

M² Platform Release v17


Latest binary version


M2LiveConfig is now set as standard for all projects.

Find documentation here: https://docs.msquared.io/tutorials-and-features/live-config

Controls & Interface: Approachable Control Scheme Improvements

Approachable and lean back navigation and interaction controls, optimised for touch or mouse-only / one handed participation.

See here for documentation: Approachable Controls | MSquared Platform Documentation

Approachable controls are designed to provide an intuitive casual user experience for our event participants. Features include:

  • Click to move (path find to location or object)

  • Click to follow (an avatar)

  • Hold to move (mouse only equivalent of manual control)

  • Automated movement speed (walk or sprint intelligently)

  • Automated camera movement

  • Edge look

  • Clickable interface for device and object interactions

Improvements for Beta:

  • Enhanced camera smoothing

  • Click to turn avatar

  • Setting standardised movement behaviors for MSquared Platform

  • Detailed usage documentation added

  • Analytics hooks added

Emotes: Emotes as Possessions

Emotes are modular possessions:

  • They are show in the user's inventory / collection as a possession

  • Different projects, roles or even users can have access to different emotes

  • Just like other possession types, emotes can be given, earned, bought or traded or taught to each other.

 Example would be earning Dance Moves in Courbet, which can then be used in events or shown to each other.

See docs: Emotes as Possessions (items) | MSquared Platform Documentation

World Objects: Microphone (Improvements)

Speakers expect the act of speaking to an audience be simple and intuitive, just like walking up to a mic in real life.

Our Microphones make it clear and easy to understand when Speakers are broadcasting to the entire group, and reduce the need for any technical or control-based understanding of the product.

This is a World object that amplifies the voice chat volume of the speaker in front of it.

Improvements for this existing capability are:

  • Audio improvements: Make it sound more authentic as if the volume is coming from the speakers placed in the venue

  • UX improvements: Make it clearer that microphone is active, replace the spatial voice chat button with a distinct microphone button (same approach used with the Loudspeaker gadget that fulfils the same functionality)

Gameplay: Quickbar Tabs & Modes

Containers for different quickbar pages and interaction modes. For example, gadgets and consumables

  • Quickbar can be (optionally) minimised and then expand from these buttons.

  • Buttons can be used to switch between different pages of the quickbar and configured according to project needs

    • For example: Press "React" button to see emotes, "Equip" button to see gadgets

  • Buttons can be shown, disabled or hidden conditionally

    • For example: People with the host or director role gets the "Host" button that expands a Quickbar containing all host gadgets

  • Buttons can change how the user / avatar interacts with the world

    • For example: Press "Place" button to enter Place Mode where MML objects are highlighted and clicking on them allows moving or configuring them (instead of walking up to them, which happens outside the Place Mode)

    • For example: Press "Camera" button to detach from your avatar and control a Drone Cam which may or may not come with its own Quickbar.

Gameplay: Inventory & Quickbar Modularity

Less opinionated shortcut interface - provides more flexibility for projects.

  • Turn Quickbar into a generic shortcut interface for items

    • For example: gadget, consumable, object, ability, emote...

    • This includes being able to present certain types of gadgets in their own quickbar tab or inventory page (e.g. gadgets and consumables being separated despite consumables technically being gadgets)

    • In the future, we will make it open to non-items, e.g. settings, locations on the map; however, current iteration is limited to items

  • Make Quickbar and Inventory less interdependent

    • For example: Option for projects to use Quickbar without Inventory without issues

      • A potential issue could be that Quickbar has max 10 slots and the player picks up the 11th item which goes to the Inventory which isn't accessible by the player - in this case a solution could be the 11th item cannot be picked up or asks to replace one of the existing slots

      • MSquared Platform enables downstream projects to use the most appropriate solution

  • Allow users to equip or use things directly from the Inventory

    • For example: Click on Growth Potion in the Inventory to drink it, you don't have to drag it to Quickbar first

  • Quickbar to gain more flexibility in terms of which content is shown on (see also Quickbar Tabs & Modes ticket)

    • For example: Project A divides Quickbar into gadget and emote pages, Project B shows them both on the same Quickbar

M² Platform Release v16


Latest binary version:


A major change in this release is the inclusion of Live Config V2 which will have affects on downstream projects.

The plan is for MSquared Release v16 to support both live config v2 and v1 - with MSquared Release v17 forcing projects to migrate to the new live config.

Documentation can be found here: https://docs.msquared.io/tutorials-and-features/live-config

Easy Anti-cheat

EAC is available to be used in projects.

Please see documentation on how to set up EAC here: Setup Easy Anti-Cheat (EAC)

Some additional work has been scoped and will progress to make EAC more secure. Updates on this will be announced in due course.

Metaverse Billing


MSquared Release v16 delivered metaverse billing as a prototype feature. This functionality proves out end-to-end billing via Stripe.

Actual delivery of this will come when metaverse owners are onboarded and we deliver any additional functionality and features as part of user story gathering.

in lieu of release highlights, please accept this picture of the Release Managers cat

M² Platform Release v14


Latest binary version: v14.0.0.243871

In-Editor Performance Estimates

Alpha Feature

Provide in-editor performance estimates for avatars, crowds and environments. This would allow the user to get an estimate of how complex those are, and what kind of scale they could expect reasonable performance.

This will help reduce the pressure on the Core and Rendering teams by providing projects with performance estimates earlier in the development cycle.

See here for documentation: https://docs.msquared.io/tutorials-and-features/performance/in-editor-performance-estimates

Low Latency Mode

Alpha Feature

Low latency mode is now default for all projects.

Docs have been updated to reflect this new, low latency default for Morpheus: https://docs.msquared.io/tutorials-and-features/networking/high-scale-mode

This means that by default, the max CCU of deployments is now around 5k

(with much lower latency), compared to ~18k previously. This decision was made as it's far more common for projects to require low latency than to require CCU above 5,000. High scale mode is being enabled in M2UP scale tests, but please remember to update this in your own project if you need above 5k CCU.

M² Platform Release v13


Latest binary version: v13.0.0.241520

Avatars : MML Sockets at Scale

See here for documentation: https://docs.msquared.io/tutorials-and-features/avatars/avatar-attachments

Ability to add sockets to our Unreal skeleton in Morpheus so that users can hold things in their hands, and customize their appearance with elements that augment their basic clothes.


Equip a gun or sword and have it show up held in the hands of their avatar.

  • Equip a hat and have it attached to a head socket.

  • Equip glasses and have them appear on their face.

  • Equip a backpack and have it appear on their back.
