OpenLM SLM v25.3 released – now supporting .NET 8 with fixes for FlexLM, RMS, and Cloud
We’re pleased to announce the release of OpenLM SLM version 25.3, which introduces essential updates for stability, accuracy, and future compatibility. This release includes a major platform upgrade and resolves several customer-reported issues across FlexLM, RMS, and OpenLM Cloud environments.
Important notice
To run OpenLM SLM v25.3, you must upgrade your environment to .NET 8. .NET 6 has reached end-of-life and is no longer supported. Please ensure your systems are updated before installing this release.
Additionally, this version requires a new license file.
Contact your OpenLM representative or support team to obtain an updated license file before upgrading.
What’s new in OpenLM SLM v25.3
.NET 8 upgrade for long-term support
The OpenLM Server installer has been updated to support .NET 8, replacing the deprecated .NET 6. This upgrade ensures better performance, security, and compatibility with modern systems.
Siemens denial tracking fixed (FlexLM)
We resolved an issue where Siemens denial messages were not captured, and license quantity information was displayed incorrectly. Denials are now accurately recorded and reflected in usage reports.
Improved token license tracking (nx_design_token – FlexLM)
An inconsistency between the license file type (“token”) and the license output (“floating”) prevented session tracking for nx_design_token on some servers. This mismatch has been addressed to ensure accurate monitoring.
Token usage reporting restored in OpenLM Cloud
Previously, token-based license usage was not displayed in Cloud reports, despite being visible in the license output. Token consumption is now correctly attributed to features and fully reported in both CCL and LAR.
RMS license usage
OpenLM now properly reports license usage and quantity data from the RMS License Manager. The system previously captured only feature data, which limited reporting capabilities.
