2023 Mendix Cloud Release Notes

Last modified: January 13, 2026

December 2023

December 28, 2023

New Features

  • We now support regional fallback in Mendix Cloud. With regional fallback, the database and file storage of your application are replicated to another Mendix Cloud region. If the primary region of your application goes down due to an outage, we will switch over to the fallback region. Your app will then be available to process requests from the fallback region. Without regional fallback, you will have to wait for the primary region to become available again. Regional fallback is part of our Premium Plus cloud resource packs.
    • Regional fallback is available in all Mendix Cloud regions except Tokyo. We will offer regional fallback in Tokyo in Q1 of 2024.

Improvements

  • If a user tries to upload or transport an MDA file that exceeds the maximum size of 1 GB, they will now see an error message warning them that their MDA file is too big.

December 14, 2023

Improvements

  • The application disk usage and CPU usage graphs on the Metrics page now have y-axes that scale dynamically, with the minimum set to 0 and the maximum set to the maximum data point included in the request.
  • Under the Deploy API v4, we increased the maximum limit value for /apps/{appId}/environments from 20 to 100. 100 is also the new default limit value. For more information, see Deploy API – Version 4.

November 2023

November 22, 2023

Improvements

  • We improved the layout and display of the Metrics page. Metrics can now be filtered via drop-down menus that set the time period (day, week, month, or quarter) and the group (application, database, or all) for the graphs. We also updated the visual style of the graphs. For more information, see Metrics.
  • We improved the layout and functionality of the Logs page. The log archives now display file size for app and access logs, and they include an option to filter logs by date. For more information, see Logs.
  • The Logs page now has an activity log, which reports data on who has viewed or downloaded the logs. The activity log records access by team members as well as members of Mendix Support, who may view or download your app's logs in connection with any support tickets you have open.

November 16, 2023

Improvements

  • We added support for sending application runtime logs and metrics to New Relic.
  • We deprecated the SPLUNK_LOGS_REDACTION and DATADOG_LOGS_REDACTION environment variables.
  • We introduced the LOGS_REDACTION variable, which is compatible with Splunk, Datadog, and New Relic.

October 2023

October 26, 2023

Improvements

  • We added support for an Origin-Trials HTTP header in the Developer Portal. To use this header, the customer must first deploy (or redeploy) their app sometime after 26 October, 12:00 PM. If the customer has deployed since this date, then they can simply set the header and restart their app to use the header. For more information, see HTTP Headers.

October 25, 2023

Improvements

  • We added support for gp3 storage instances for databases; this provides higher baseline storage performance compared to gp2. IOPS and throughput performance will be upgraded according to the table below.

    • From October 25 onwards, when a customer creates a new DB instance, it is provisioned with a gp3 storage instance if it has a storage size of at least 20 GiB (as specified in the table below). This also occurs when the customer's database is recreated.

      Storage SizeStorage Instance TypeBaseline Storage PerformanceProvisioned IOPS RangeProvisioned Throughput Range
      Less than 20 GiBgp2100 IOPS (3000 Burst) / 125 MiB/s100 - 1197 IOPS128-250 MiB/s
      Between 20 and 400 GiBgp33000 IOPS / 125 MiB/sN/AN/A
      400 GiB and highergp312000 IOPS / 500 MiB/s12000 - 64000 IOPS500 - 4000 MiB/s

    • Existing databases eligible for this upgrade will be migrated later. More details will follow.

    • For more information, see Database IOPS Burst Balance in the Metrics documentation.

Fixes

September 2023

September 19, 2023
