Nexus Repository Manager 3.1.0 Release Notes

These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.1.0.

See the complete release notes for all resolved issues.

New and Noteworthy

Building on the solid OSS foundation, Nexus 3.1 is the first Pro release of the 3.x platform and the first 3.x release to support upgrade from 2.x.

Upgrade from Nexus 2.14.1 is supported!

Nexus 3.1.0 is the first 3.x series release that supports upgrade from Nexus 2.14.1 and greater. Please review our upgrade guide for more information on the exact steps required.

Changes To Default Installation and Work Directory Layout

Version 3.1 changes the default locations of core installation files relative to your specific work and data. It now more closely mimics the familiar pattern that Nexus 2.x followed. For users upgrading from 3.0.1/3.0.2, we strongly recommend adopting these defaults by following our special upgrade instructions.

Common Server Customizations More Easily Persisted Across Upgrades

Now you can store your server configuration files changes directly in the data directory, making backups and upgrades straight forward. Upgrades will involve fewer manual changes while easily picking up sensible default values for any new features.

Upgrading from 3.0.x? Follow these Instructions

We have special instructions for users upgrading their 3.0 installs to 3.1.

Nexus Professional Features Support

Existing Pro customers can install their licenses into this version and begin to take advantage of advanced enterprise features.

UI Based Installer Distribution is Suspended

For the near future we have decided to remove the UI based installers. If you have previously used these installers, please review our article for more information.

Security Issues Resolved

As part of our continuous auditing, a number of potential UI exploits and vulnerable third-party dependencies have been fixed in this release to make a more secure product.
