Changed behavior

When you use the version 3 metering resource to download usage data, the REST API can’t export a ZIP file greater than 50 MB.

Previously there was no size limit, which could cause OutOfMemory errors.

Elastic RTE Manager role

We renamed the existing Elastic RTE Manager role, which was previously named Elastic RTE Dev Ops Engineer.

For more information about user roles, see User Administration.

Field name changes in ClusterConfig API calls

In ClusterConfig API calls, the following field names were changed in the systemDiskConfig and dataDisksConfig objects:

For more information, see REST API Reference.

Fingerprint authentication always on

IDMC performs a fingerprint authentication check every time a Secure Agent starts up and sends an alert to the notifications tray when there’s a mismatch.

Previously, you could turn off fingerprint authentication checks and IDMC sent mismatch alerts by email only.

For more information, see Organization Administration.

Git repository verification

When you use GitHub, GitLab, or Bitbucket for source control, IDMC saves a local copy of the repository. To ensure that the correct repository is used, IDMC now verifies that the saved copy matches the repository that you request during a source control operation.

After the October 2026 upgrade, the first time you connect to a repository that was saved before the upgrade, IDMC creates a fresh copy instead of reusing the cached repository. This process can take extra time depending on the size of the repository and your network speed. Subsequent connections use the new copy as usual. IDMC doesn't delete the old saved copies automatically. Administrators can clear the old copies from the cache to free up disk space.

Master node requirements for elastic runtime environments

To set up an elastic runtime environment, the master node needs 60 GB of free disk space to account for additional libraries. Previously, the master node needed 50 GB.

For more information, see Runtime Environments.

Multi-factor authentication by default

IDMC enables multi-factor authentication by default for native human users in new organizations.

For more information, see User Administration.

Password confirmation for email updates

When users update their email address, they are now required to enter their current password to initiate the change.

Previously, no password confirmation was needed to update an account's email address.

For more information, see User Administration.

Resetting users

You can reset disabled SAML users who were not provisioned using SCIM.

Previously, the option to reset a user wasn't available for organizations configured to use SAML.

Scraping Secure Agent details

The Secure Agent details page changed in the October 2026 release. If you employed web scraping to extract information from this page, you must update the scraping script for the new user interface.
