Version	Client	Server	Configurator
4.0-RC1 29 Mar 2023	Completely new graphical user interface design New opening screen, more user-friendly experience, particularly for first-time users Main options/buttons moved from the top to the left to save space, now that monitors are generally wider Redesigned layer select and legend window (used to be called 'active layers' window), layers can now be text-searched as well Redesigned plan creation workflow and resulting windows Redesigned plans monitor, plans can now be ordered in different ways as well New tutorial mode added to help first-time users understand what this is all about and how things work (also making all old Youtube tutorial videos now irrelevant) Option to return to opening screen, so you don't have to shut down the game to switch sessions anymore	Further porting into Symfony (this will continue with every release) Improvements to client-server communications New graphical user interface design also applied to Server Manager, Knowledge Base, Community Wiki and main website Complete redo of our authorisation service now under auth2.mspchallenge.info, based on Symfony and Webpack Assorted bug fixes, notably concerning energy plans and the websocket service	No change
4.0-beta10 14 Jul 2022	Completely new design of the Impact Tool (icon in top-right corner), now based on hierarchical edge bundling Overhaul of communication with the server, now receiving updates through a separate websocket connection Updated to Unity version 2020.3.31f1 Assorted smaller bug fixes	Overhaul of communication with the client, now sending updates through a separate websocket service First introduction of Symfony 5.4 PHP framework (future versions will integrate with it much more strongly), which partially made the websocket service possible Overhaul of Knowledge Base; now each layer has its own page with tabs explaining any sea basin specifics (rather than the other way around) Knowledge Base also simply has more and more pages with relevant content All default session configurations (North, Baltic, Adriatic Sea, North Sea Digitwin, Clyde Marine Region) now refer to many more relevant Knowledge Base pages Refactor of the full platform installer, now using portable version of XAMPP, and of course now installing Symfony and all its dependencies	Altered format of the 'dependencies' object, required to feed the Impact Tool (see Client) with data. As a result configuration files developed/altered with Configuration Editor beta9 can unfortunately no longer be loaded in beta10. Read more about this on the installation page.
4.0-beta9-2 11 Feb 2022	Complete deprecation of concurrent layer requests during loading Fixes problem of sometimes not showing KPIs (ecology, shipping and/or energy) Fixes problem of certain values or null values of raster layers not being shown Incomplete polygon or line drawings are now no longer stored on the server	No change (this is a client-only hotfix release)	No change (this is a client-only hotfix release)
4.0-beta9-1 2 Dec 2021	Tooltips no longer hidden underneath drowndown menus Loading screen no longer overburdening the server with concurrent layer requests	No change (this is a client-only hotfix release)	No change (this is a client-only hotfix release)
4.0-beta9 24 Nov 2021	Code signed to disable OS / anti-virus / browser warnings (also applies to all installers) New feature: Impact Tool (icon in top-right corner) Altered server communication Assorted bug fixes, particularly concerning missing plan updates	Contains new North Sea Digitwin configuration file with which to create server sessions. Contains new Adriatic Sea configuration file with which to create server sessions. Watchdog now handles simulation tick checks instead of the client UpdateServerList script to sync ServerManager database with key data from session databases is now deprecated MEL now only runs if required raster files are actually available ServerManager session details GUI updated Assorted bug fixes to ServerManager	Accepts an additional 'dependencies' object, required to feed the Impact Tool (see Client) with data
4.0-beta8-1 21 Apr 2021	Fixes invalid geometry errors returned for lots of complex existing polygons	Fixes database migration error when logging on to the Server Manager for the very first time after installation Fixes occasional player login bug when the session has no player password defined	No change (this is a client/server hotfix release)
4.0-beta8 14 Apr 2021	Enables more advanced authentication and logged-on user count (see also Server column) Fixes problem obtaining output from external LCoE API (North Sea Digitwin specific problem) Fixes very minor GUI issues	Allows more advanced session end-user authentication, notably logging on with an MSP Challenge account or through some other authentication provider Enables defining other GeoServers in ServerManager Enables upgrading existing beta7 sessions to beta8 Improves ServerManager GUI Adds text labels to ports and cities in the default North Sea, Baltic Sea and Clyde marine region configurations Assorted code refactoring (more to come) Note: beta8 servers are to an extent backwards compatible with beta7 clients.	No change
4.0-beta7-2 11 Mar 2021	Fixes crash when clicking on a bit of geometry (to open the Properties window) that has null value metadata in it. Orders layers within the Layer Select Window alphabetically.	No change (this is a client-only hotfix release)	No change (this is a client-only hotfix release)
