Sonatype Nexus Repository 3.81.0 Release Notes

Released June 10, 2025

Known Issue in 3.81.0: dotnet restore Command Fails

We’ve identified an issue in Nexus Repository 3.81.0 that causes dotnet restore commands to fail due to NuGet v3 content requests returning 404 errors. This can disrupt build pipelines that rely on NuGet group repositories. If your environment uses the dotnet build tool, do not upgrade to 3.81.0. A fix is in progress and will be released as soon as possible.

What’s New and Noteworthy in This Release?

Egress Information Available in Licensing Usage Tab

Sonatype Nexus Repository now provides egress information for on-prem instances; administrators can find this information in the Usage tab under Settings > System > Licensing. This new feature helps you understand your data transfer patterns, making it easier to plan for a potential cloud migration. By seeing your egress data upfront, you can better estimate costs and resource needs in a cloud environment.

Note that Total Egress is calculated at the application level. This might differ from network transfer measurements from your cloud provider. Our testing indicates approximately 15% more traffic when estimating total egress in cloud environments.

For full details, see the License Management help documentation.

Enhanced Security and Performance with Jetty 12

This release upgrades Sonatype Nexus Repository from Jetty 9 to Jetty 12, bringing enhanced security and performance to your instance. This upgrade ensures that Sonatype Nexus Repository operates on a supported and modern server technology.

If your Sonatype Nexus Repository instance uses a customized Jetty configuration, serves HTTPS directly through Sonatype Nexus Repository, or has a customized request log, plan to update your configurations accordingly.

Performance Improvements for Change Repository Blobstore in Google Cloud Environments

This release includes performance improvements for the Change Repository Blob Store task when moving from one Google Cloud Storage (GCP) bucket to another. Previously, this operation took considerably longer than other blob store migration types. This enhancement greatly improves the efficiency of managing your Google Cloud Storage-backed repositories.

Integrate Sonatype Repository Firewall with Zscaler for Enhanced Malware Protection

Sonatype Repository Firewall now integrates with Zscaler, a cloud-native cybersecurity platform, to provide an additional layer of defense against actively verified malware components. This integration automatically blocks malicious components from being downloaded directly from public repositories, protecting your organization from malware found in "shadow downloads."

For details on how to enable this protection, see our Zscaler integration help documentation.
