Nexus Repository Manager 3.5.0 Release Notes

These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.5.0.

See the complete release notes for all resolved issues.

New and Noteworthy

Yum Proxy Repository Support

You can now define Yum proxy repositories. In Nexus Repository 2, Yum support was built on top of maven repositories, this time around, we’re building yum as a first-class format.

Yum hosted and group repository support will be in a yet to be announced future release and this time around we’re building Yum support to be platform independent such that it will not have a dependency on the external createrepo program.

Note that upgrading Nexus 2.x Maven 2 format Yum enabled proxy repositories is not supported - your new Nexus 3.x Yum proxy repository will download remote rpm files and metadata as needed. Give it a try and let us know what you think!

Upgrade Support for Firewall Enabled Repositories

For Firewall customers looking to upgrade their Nexus Repository instances from 2.x to 3.x, we’ve enhanced the upgrade wizard with support for quarantine-enabled repositories. This means that when you upgrade a 2.x instance to 3.x, the audit and quarantine history is upgraded along with it.

Upgrading to Nexus Repository 3.5.0 from 2.x requires the just-released Nexus Repository 2.14.5. IQ Server 1.33 is also a required minimum for upgrading Firewall-enabled repositories.

Upgrading from 2.x

If you’re upgrading from Nexus Repository 2, you must first upgrade your installation to 2.14.5. See the upgrade compatibility matrix for more information.

Changes to Startup Files

A JVM optimization was making debugging some of your reported issues difficult; we have corrected this by changing the default JVM options. [ NEXUS-13777 ]

Picking up this change will require the following line in file bin/nexus.vmoptions (now the default):

-XX:-OmitStackTraceInFastThrow

Per-Task Log Files

Scheduled tasks will now output to their own log files allowing for cleaner separation of task log output from regular log output. Task logs are retained up to 30 days and can be found near the existing log files under sonatype-work/nexus3/log/tasks.
