  • Posting comments to a discussion on the Buzz sometimes took a long time to complete. We made a change so that comments now appear almost instantly after hitting the Post Comment button. This change will also speed up completing sprints with stories which have associated feedback items.

April 1st, 2017

March 20th, 2017

  • We introduced a new setting in Node Security, you can now configure Monitoring Permissions separately from Transport Permissions. Immediately after this change, we granted all users that had Transport Permissions on an environment the Monitoring Permissions there as well. From now on, a Technical Contact can configure these settings for everyone in the team separately. While we introduced this setting, we revisited the layout of the Node Security screen, you now have a simpler interface to change the permissions en each environment.

February 21st, 2017

New Features

  • We added the View App and Edit App buttons. The View App button brings you to the deployment URL of your Free App, or, if you have test, acceptance, and production environments, it lets you choose between these environments using a drop-down menu. The Edit App button will launch the Desktop Modeler if you have it installed; if you are part of the partner group testing the Web Modeler, then you’ll have the choice to directly open your app in the WM.
  • We redesigned the interface. The new look sports light colors and a responsive layout. Menu items pertaining to your apps have been moved from the top to the left-hand side. Users with permissions to access restricted parts of the Mendix App Platform can navigate there using the Profile menu, which opens when you click your avatar in the top-right corner of the screen.
  • We improved the breadcrumbs. A header on top of the Mendix App Platform will show you where you are in the navigation structure.
  • The Feedback widget can now be used when opened on small screen sizes (for example, on a smartphone).

October 5th, 2016

  • On Webkit-based browsers such as Safari a “connection error” dialog would sometimes pop up while loading the Dev Portal, after which the page would continue to load normally. We now prevent this dialog from appearing so that people can open the Dev Portal uninterrupted.

  • Advanced Runtime Settings can now be configured for the paid tiers in Mendix Cloud applications. You can find a list of all custom settings here: Custom Settings
  • The advanced settings LogMinDurationQuery and ClientQueryTimeout have been enabled by default. LogMinDurationQuery will print all database queries that take longer than 10 seconds to the application log and ClientQueryTimeout will cancel database select queries triggered from the Client that take longer than 15 minutes, which is when the http timeout has kicked in so the results can not be delivered and the query can safely be killed. A restart of the application is required for these changes to take effect.

January 13th, 2016

  • The Technical Contact of an application can now assign other people as the Technical Contact using the Node Security tab in the Project Settings on https://home.mendix.com/.

December 1st, 2015

  • The Mendix Cloud switched from the Jetty blocking I/O connector to a selector based non-blocking I/O connector for all applications. Due to a bug in the blocking I/O connector HTTP requests could be fired multiple times for long-running (> 2 minutes) requests, which would result in strange results in the Mendix Debugger (ticket 462699). If you want to apply this fix you can simply restart your application.
