Version	Client	Server	Configurator
4.0-RC3 11 Jul 2023	Now offers reasons a certain plan would require approval from certain other countries Now by default obligates approval from all countries when fishing fleet effort policy is changed (even if it only concerns one country) Updates layer and map icons Offers a server description in the Sessions screen, if available Finishes first versions of help overlays (under ? icon) for all windows Fixes bug asking confirmation twice when deleting an objective Fixes bug sometimes crashing the client when returning to server login / sessions screen Fixes bug with and improves plan message window Fixes bug with Read More links under News (Mac only) Fixes bug with Shipping Safety Zones and Fishing Effort policy plan updates Fixes bug with updating restrictions between layers after a geometry change	Sends a server description to connecting clients, configurable through the Server Manager's Settings tab Completes profiles of all countries involved in current sea basin editions on the Knowledge Base Harmonises layer and layer type names, colourings, and icon use between different sea basin editions, thereby also improving accessibility North Sea edition now no longer has the National Shipping Lanes layer to plan with Baltic Sea edition's shipping simulation bug fix, related to Sodertalje fairways Updates/fixes ecosystem pressures in different sea basin editions First experimental version of Docker containers - available for testing, use at own risk!	Now accepts pure string text for layer's category and sub-category Now accepts under MEL (ecosystem simulation) a boolean stipulating whether all countries should approve any change to any fishing fleet efforts Adds Bathing sprite as an option for map icons
4.0-RC2 18 Apr 2023	Now opens in windowed mode by default rather than full screen Now opens all web links in the user's own default browser external to the game, rather than an in-game browser Turns logo in top-left corner to a team colour indicator, with a window showing other team members currently logged in Adds first versions of Help overlays for a lot of the windows (more and more polish to come) Upgrades design and functioning of the Objectives Monitor, removes the separate small KPI windows as they are redundant Bug fix: rescaling the GUI no longer offsets geometry multi-select during plan editing Bug fix: News in opening/log-in screen now shown in correct order	Adds API endpoint for returning currently logged-in user list First polish on the shipped edition configuration files (North Sea, Baltic Sea, etc.) to harmonise and simplify terminology and colour coding (more to come) Bug fix: Demo sessions now automatically restart again Bug fix: websocket service now properly returns a plan's energy grid to the client	No change
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.
