General fixes

• Further extended the amount of time the Test Call Home function will wait for the ticket to be received.
  
• Fixed an issue that can cause SRCs E3550421, E3D46FFF, or E3D43103 to be reported when an HMC with a firmware version earlier than 1030 tries to use a discovered HMC with version 1030 or later as a call home server.
  
• Fixed a rare issue that can cause the number of serviceable events shown on the GUI dashboard and the GUI Login screen to differ from the actual number of serviceable events as shown on the Service management -> Serviceable events GUI view.
  
• Fixed an issue that can cause an out of memory condition that results in a service processor dump on an Enterprise BMC-based managed system.
  
• Fixed a timing issue that can cause physical I/O adapter descriptions and feature codes to be incorrect or missing after an HMC restart.
  
• Fixed an intermittent issue that can cause the new Resource roles GUI to not show any resource roles.
  
• Fixed a rare issue that can cause the following message to be displayed when trying to display partition properties on the new GUI: Cannot invoke "java.util.List.isEmpty()" because "systemTypes" is null.

• Fixed FreeType vulnerability: CVE-2025-27363
  

Known Issues and Limitations

• When the HMC's locale is set to a locale that ends in @euro or @preeuro, the local console GUI will not load after logging in. To work around this issue, change the HMC's locale to a locale that does not end in @euro or @preeuro. Locales that end in @euro or @preeuro will be removed in a future release.
• Setting the Microsoft Edge browser to a language not supported by the HMC will cause Learn More links on the GUI to fail to launch help pages with the message "The requested help document was not found."
  
• Dates, times, and numbers on the GUI Performance dashboard are shown in the format based on the HMC language instead of the browser language.
  
• Occasionally a Kerberos user login may fail even when the credentials are valid. As a workaround, try logging in again with the same credentials after a short delay of 15 to 30 seconds.
  
• Using the search function on the Partitions table on the new GUI takes several seconds to update the table when the HMC is managing many partitions.
  
  

Best Practices

• User sessions - The following best practices helps avoid performance degradations gradually over a period of time due to increased login sessions as well as security vulnerabilities such as unauthorized access to the active HMC sessions.
• It is a best practice to logoff from HMC UI and then close the browser tab instead of directly closing the tab
• Set Idle session timeout for all the users and not leave the timeout as '0' which leaves it as no timeout.
