2017 Release Notes

Repository Manager 3.7.1


Sonatype is pleased to announce the immediate availability of Nexus Repository 3.7.1. A summary of the highlights in this release is shown below.

Offline Repositories for Tree/HTML views [NEXUS-15278]

This release fixes an issue where some content may be missing in the tree or html views for offline repositories. We highly recommend users of 3.7.0 upgrade to this patch release.

Repository Manager 3.7.0


Sonatype is pleased to announce the immediate availability of Nexus Repository 3.7.0. A summary of the highlights in this release is shown below.


If you upgrade to 3.7.0 from a version that has a repository marked offline, then the new Tree View feature introduced in 3.7.0 may fail to render all repository content. This known issue does not cause builds to fail or the search user interface from working, only tree view is affected. This issue is resolved in 3.7.1 and newer.

Tree and HTML views replace prior Browse features

NEXUS-12531, NEXUS-12518

The browse experience has been upgraded to include a Tree View and HTML View to help you find your assets faster and easier. During this process, we also exhaustively tested for scale and upgrade across all formats. The search experience remains the same as prior versions.

When upgrading, Nexus Repository Manager will automatically begin creating the tree node data. Depending on hardware, this data should take ~30 minutes to process 3 million assets and the storage of the component database should increase by ~30%. While the assets are being processed browse will display a partial tree.

NPM command line Search restored


npm deprecated the /all/ endpoint to their search interface earlier this year. This improvement restores npm search via that interface by enabling the replacement /v1/ endpoint. We took this opportunity to add some scalability and performance tweaks as well.

Repository Manager 3.6.0


Sonatype is pleased to announce the immediate availability of Nexus Repository 3.6.0 OSS and Pro. A summary of the highlights in this release is shown below.

Docker Anonymous Support


This change makes it possible for anonymous users to be granted read-only (pull) access. It's enabled by a new Docker repository connector option and realm. Anonymous read support can be deactivated by default and must be enabled on each Docker repository individually. Ultimately, this is useful as it allows users to consume and share Docker images with no credentials needed.

Goodbye JEXL, Hello CSEL


We've discovered that Apache JEXL based content selectors aren't fast enough for our upcoming tree view feature, which does many more evaluations than other browsing methods. To address this we’re introducing our own Content Selector Expression Language (CSEL) to support current features, such as Upgrading, and future improvements that rely on optimal performance.

Nexus Repository will automatically upgrade as many of your existing JEXL selectors to CSEL selectors as possible. Any remaining JEXL selectors will continue to function but with this new expression language in place, future releases of the repository manager will be more performant.

Provisioning API and Group Repositories


Groups repositories created through the provisioning API will now preserve the order of their members. Previously, the initial ordering was set correctly, but jumbled on server restart.


For existing repositories affected by this, the workaround is to load the group repository in the UI, reorder the members as desired, and save.

Firewall and IQ Server

Firewall now requires theIQ Server connection capability to be configured and enabled. Previously, it would process transactions (e.g. audit) regardless, but a recent change now requires this capability.

Upgrading from 2.x

If you’re upgrading from Nexus Repository 2, you must first upgrade your installation to 2.14.5.

Repository Manager 3.5.2


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.5.2.

New and Noteworthy

This is a targeted release to address excessive thread creation associated with task progress logging.

The vast majority of customers will benefit from updating to this release.

General Improvements

Task Logging

  • [NEXUS-14227] Bug Thread count increases linearly with scheduled task execution

Repository Manager 3.5.1


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.5.1.

New and Noteworthy

The vast majority of customers will observe no immediate benefit from updating to this release.

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.

General Improvements


  • [ NEXUS-14087] Improvement upgrade OrientDB dependency to version 2.2.26

Repository Manager 3.5.0


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.5.

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 1.33is 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.

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):


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. [NEXUS-13352]

Repository Manager 3.4.0


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.4.

New and Noteworthy

Upgrading from 2.x

If you’re upgrading from Nexus Repository 2, you must first upgrade your installation to 2.14.4.

Updated System Requirements: Increase Default File Handle limits

On Linux and Mac OSX installs, the default process file handle limits available may be too small and may cause data corruption or other significant problems if not explicitly increased. We recommend all deployments ( even previous versions) raise their available file descriptors to 65536 immediately. How to implement this change is summarized in the system requirements. [ NEXUS-12041 ].

General Performance/Scalability Improvements

All sorts of performance optimizations for existing features are in this release, primarily with scheduled tasks, browse and search. Issues which were causing OutOfMemory errors were also squashed. We continue to schedule fixing any remaining severe issues with extreme prejudice and we are confident this is the best performing 3.x release to date.

Repository Manager 3.3.2


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.3.2.

See the complete release notes for all resolved issues.

New and Noteworthy

Browse Performance

Browsing large repositories especially with a UI text filter added, could take longer than the UI timeout of 60 seconds to complete. We have optimized internal queries to mitigate this effect. [ NEXUS-13095 ]

Search Performance

There have been multiple reports of slow or incomplete asset and component search. Under some circumstances, assets recently published or proxied into a repository would not show up in search results (despite being visible in browse and retrieval by client tooling). This behavior was due to the default indexing configuration which silently ignored over-capacity indexing requests. We’ve switched to a bulk indexing mode, which avoids this.[ NEXUS-12520 ]

NuGet Client Query Performance

Under some circumstances, NuGet ODATA searches could take unacceptably long to complete. Performance has been improved significantly through query optimization. [ NEXUS-12983 ]

Upgrading from 2.x

If you’re upgrading from Nexus Repository 2, you must first upgrade your installation to 2.14.4 .

General Improvements

Browse Storage

  • [NEXUS-13140] Improvement when browsing assets in a group repository the asset summary UI should display the containing member repository name

  • [NEXUS-13095] Bug Browse components of large repositories fails with IllegalStateException Timed out reading query result from queue performance


  • [NEXUS-12983] Bug NuGet FindPackagesById queries may perform slowly possibly leading to general non-responsiveness performance


  • [NEXUS-12520] Bug assets visible by browsing are not available when searching due to non-optimized elasticsearch configuration rebuilding indexes

  • [NEXUS-12681] Bug search assets or components UI slower to respond than expected with large datasets performance

Repository Manager 3.3.1


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.3.1.

New and Noteworthy

This is a targeted release to address some key issues with blob store operations.

Refetch Proxy Repository Content When a Blob is Missing

Prior to this release, if the blob (binary content) for proxy repository asset was marked as soft-deleted, an error would be logged return 500 status returned to the calling client. Now, the content will be re-fetched from the remote and if still not available, an appropriate 404 status will be returned. [ NEXUS-12388].

We have also made two internal improvements to blob write operations under concurrent load in order to increase resiliency. [ NEXUS-13030, NEXUS-13032 ]

Record Blob Soft-Deletion Reason

Soft-deleted binary content intentionally remains on disk until the blob store is compacted. In rare cases some blobs were being referenced as soft-deleted unexpectedly. To help diagnose such a situation, the reason a blob is soft-deleted will be recorded in its accompanying .properties file. [ NEXUS-13035]

Upgrading from 2.x

If you’re upgrading from Nexus Repository 2, you must first upgrade your installation to 2.14.4 .

General Improvements

Blob store

  • [NEXUS-13030] Improvement automatically retry blob creation when a UUID collision is detected

  • [NEXUS-13035] Improvement add a diagnostic reason for soft-deleting a blob to the blob properties file


  • [NEXUS-9872] Improvement misconfigured docker proxy URL should log more details about critical failures at default log levels

  • [NEXUS-12793] Bug if java.lang.Error is thrown during request processing it may not be logged at default log levels

Proxy Repository

  • [NEXUS-13032] Improvement eliminate soft-deleted blobs and reduce transaction retries for identical proxy repository asset requests performance

  • [NEXUS-12388] Improvement attempt to refetch proxy repository content from remote when a referenced local blob is missing

Repository Manager 3.3.0


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.3.

New and Noteworthy

Git LFS Support

Nexus Repository is first to market with free support for Git LFS.

Downloading or sharing large binary files, such as videos, images, audio recordings, and database files, can slow down the development process and negatively impact the performance of a DevOps tool chain. By managing these components in Nexus Repository, organizations can save time and benefit from increased availability, ease of file sharing, and the ability to better control access to Git LFS components.

Nexus Repository lets you store all of your software binaries, including Git LFS in a single location. With the introduction of Git LFS support, Nexus Repository now offers free support for eight components formats, including: Java, npm, NuGet, RubyGems, PyPI, Bower, and Docker.

Once you give our Git LFS support a try, we would love to hear how this feature works for you. Let us know at

Repository Health Check Revamped!

We’ve made a significant overhaul to how Repository Health Check (RHC) works. Our goal was to make it easier for repository administrators to not just understand, but to improve the health of their repositories over time.

RHC now shows the top five components in need of remediation, prioritized by the severity and impact of the vulnerability. It also provides download trends to help you understand how the health of your repositories is changing over time.

If you are using Nexus Repository and have not yet turned on the RHC feature, start today. What’s the urgency? Perhaps you have not read the 2016 State of the Software Supply Chain Report that indicated 1 in 16 open source components downloads has a known security vulnerability. It’s time to know what’s in your repo.

Browsing and Proxy Repository Performance Issues Squashed

We continue to squash performance issues as they surface. This release includes some significant fixes that were affecting proxy repository cache throughput and Browse UI rendering. Try this new release - you should notice immediate gains in performance especially in these areas.

We are working some known issues with Search performance and we hope to have these rectified soon.

Upgrade Improvements and Requirements

If you’re upgrading to 3.3 from Nexus Repository 2.x, you must first upgrade your installation to 2.14.4.

We've corrected an issue where the upgrade process could fail if it encountered invalid or corrupt NuGet components in the 2.x repository.

We’ve also tightened the validation of proxy repository configuration to prevent blank or invalid remote repository URLs. Before upgrading to 3.3.0 from 3.2.1 or earlier, please ensure that your proxy repository remote URLs are valid.

Repository Manager 3.2.1


These notes are a compilation of improvements and significant bug fixes for Nexus Repository Manager 3.2.1.

New and Noteworthy

This release is heavily focused on high-priority bug fixes and support reducing upgrade impediments from Nexus Repository 2 to 3.

Known Issues Affecting Upgrades from Nexus Repository Manager 2 to 3

Along with 3.2.1, we released version of Nexus Repository 2.14.3. If you wish to upgrade from Nexus Repository Manager 2 to Nexus Repository Manager 3, you must upgrade to 2.14.3 at a minimum first.

Proxy repositories now afford options to enable circular redirects and store HTTP cookies. For example, you can enable the settings for the Oracle Maven Repository ( This achieves parity for upgrading Nexus 2.14.3 to Nexus 3.2.1. [NEXUS-10164]

During an upgrade from Nexus Repository 3 to version 2, HTTP requests contained encoded slashes in the URL denoting the pathname of a downloaded component. These encoded slashes caused issues when version 2 ran behind a reverse proxy. This issue has been resolved. [NEXUS-11909]
