Nexus Repository 3.29.0 - 3.29.2 Release Notes

Nexus Repository Manager 3.29.2


If you installed 3.29.1 and modified or created a cleanup policy the following is critical.

A bug in the implementation of the new user interface for Cleanup Policies resulted in a value displayed as days being interpreted as seconds. If you created or modified a cleanup policy while using 3.29.1 after updating you must confirm that these fields have the intended values.

NEXUS-26251 - Interface for Cleanup Policies erroneously interprets and persists values as seconds instead of days

Nexus Repository Manager 3.29.1


These notes are a compilation of significant bug fixes for Nexus Repository Manager 3.29.1.

An upgrade to 3.29.2 or newer is strongly recommended especially for instances that use Cleanup Policies. If this is not possible, any 3.29.1 instance is advised to take the following action:

  1. As an Administrator user, navigate to AdministrationSystemTasks.

  2. Select the task of type Admin - Cleanup repositories using their associated policies. The default task name is Cleanup service. Click the task Settings tab.

  3. Uncheck the Task enabled checkbox on the Settings tab and click Save.

These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.29.0.

Filtering npm Package Root Metadata

A common pattern in npm projects is to use version ranges for dependencies for users of Nexus Firewall this could lead to build failures if quarantine is enabled for unknown components when builds occurred before a package was catalogued. Firewall is now smarter, and when configured it will filter new packages that haven’t yet been vetted for quality so developers can use latest and version ranges without friction.

Deprecating /service/metrics/healthcheck

[NEXUS-19840] The /service/metrics/healthcheck endpoint has been deprecated and scheduled for eventual removal. It is recommended to use the alternative endpoint/service/rest/v1/status/check which has a near equivalent JSON response, except it does not return 500 status when one or more system status checks fail.

Support for Maven and Gradle SHA256/SHA512 Hashing

These hashes are now created automatically during UI Upload of jars and automatically removed when the accompanying components are removed by cleanup policies or maven-specific deletion tasks.

Remote URL of Defaults to V3 for New Installs

[NEXUS-25506] New installs will now contain the default NuGet proxy repository as Upgrading will not modify any existing remote URLs, although users are encouraged to start migrating away from using NuGet V2 API URLs such as the previous default (

More Secure Direct Inbound HTTPS Connection Ciphers and TLS Protocols

[NEXUS-20267, NEXUS-25786] For instances using Eclipse Jetty-based direct inbound HTTPS connections (no reverse proxy), the default connector configration inside jetty-https.xml now only allows TLS v1.2 connections. Excluded are weak ciphers, deprecated TLS v1 and TLS v1.1 protocols.

It is possible that very old insecure HTTP clients may fail establishing an HTTPS connection to repository manager using these new defaults. Should this occur and you need to revert changes in your instance, consult the JIRA issues or our knowledge base article.
