Infrastructure Reliability

Updated internal Go library versions for the Tenable Enclave Security operator to improve service stability and security.

• Fixed an issue where the license expiration check did not correctly prevent blade installation when a license was expired.

• Resolved an error in Exposure Response that prevented data retrieval when sorting by the Plugin Count field in the My Affected Assets view.

• Resolved a scheduling error where the last day of the month was calculated incorrectly for February during leap years, which previously caused monthly scan failures.

• Fixed a critical deployment issue where fresh installs of Tenable Security Center failed if a PostgreSQL port was not explicitly defined.

• Resolved an issue where the backup and restore process did not account for containerized database environments.

• Fixed an issue where installation logs were moved to a temporary location, making troubleshooting difficult during failed installations.

• Corrected the text in scan settings to accurately reflect "exclude all" for scan exclusions.

• Fixed an issue in the Assets > Images view where sorting functionality was unavailable for the Registry Type column.

• Resolved a bug that occasionally prevented access to the Exposure Response interface.
