New and Noteworthy
jetty-http-redirect-to-https.xml removed and its use discouraged
NEXUS-20269
Following security best practices the example configuration file that redirects inbound HTTP requests to HTTPS requests has been removed from the distribution. Startup will fail if your configuration references the file and it cannot be found.
Should it still be needed, instructions for adding it back are available.
Ability to Clean Up by "Never downloaded"
NEXUS-19424
In past versions of cleanup, you could clean up by Last Downloaded but components with no download date would be ignored. This new function allows the ability to include in Cleanup items that have never been downloaded. In this case, uploaded date will be checked instead. In addition to the ticket, see Cleanup Policies documentation for more information.
R Format Support
NEXUS-9837
Nexus Repository Manager now provides native support for R repositories. R is a language used for statistical analysis and machine learning.
Yum and CentOS 8
NEXUS-21311
Since the last NXRM release, CentOS 8 was released and it was found that NXRM did not function correctly with it. Full support is now added.
Enhanced npm login for private repository usages
NEXUS-12456
Added support for "npm login" bearer token authentication to proxied upstream npm private repositories.
npm whoami support
NEXUS-13433

$data-dir/etc/fabric/hazelcast-network.xml
to include the new section.
Also, if you're using HA-C TCP/IP discovery an additional configuration property is needed in $data-dir/etc/nexus.properties. See the HA TCP/IP Discovery documentation for details.
New and Noteworthy
Routing Rules
For users with strict security controls we've added a feature we've called Routing Rules which can be used to prevent requests from being sent to external proxy repositories. This can for example allow users to block requests containing codenames from leaking to external repositories.
Apt Format Support
As part of our widespread format support we've begun to move one of the plugins from our great community members which supports the apt format into the core product. (Limited to single nodes in this release.)
Go Format Support
Supporting the burgeoning Go community we've added native support for go repositories. (Limited to single nodes in this release.)
Beta Provisioning REST API
We've continued to add to our REST API with new endpoints to support operations on users, and user tokens. In this release they are flagged as beta, please take a look at our API documentation in the administration part of the user interface and submit feedback.
Setup Wizard
New instances as well as instances which have not changed anonymous configuration will prompt administrators upon logging in to confirm that anonymous users should be allowed to access the system. Similarly if the admin user is using the default password then upon logging in they will be required to change the password.
Removed Recent Connections Accesslog Database
The "accesslog" database which tracks recent unique connections has been removed, along with the Recent Connections section of the administration interface. This removal in no way impacts the request.log text file.
Reduced Logging for Missing Task Listeners
NEXUS-19224
Unnecessary logging of missing task listeners has been reduced.
Repository Manager 3.16.2
2019-05-31
Sonatype is pleased to announce the immediate availability of Nexus Repository 3.16.2.
The only fix in this release is for users of high availability.
Log entries for errors of "Task Already Running"

Sonatype is pleased to announce the immediate availability of Nexus Repository 3.16.0. A summary of the highlights in this release is shown below.
New and Noteworthy
REST Node Status Endpoint
NEXUS-18949
If you are running a cluster, or otherwise monitoring node health, you need a simple check to determine if your node should receive requests. To meet that need, we have added a new REST endpoint, /v1/status/writable. This endpoint returns a 200 status code when the node is ready to process requests. It's perfect for integration with load balancers to remove a node from the active set when it becomes unhealthy and return it after the node has been recovered. See the documentation Status API for more.
Support Zip Improvements
NEXUS-18711
Getting all of the necessary support zips can be arduous in a HA-C environment. Administrators no longer have to access each node to generate support zips. Generating support zips will have the option to generate them on all nodes instead, and the pop up window will have a tab per node.
Previously, gathering support zips was a GUI driven process. So administrators could not use scripts to automate gathering support zips. The new REST endpoint, /v1/support/supportzip, gives programmatic access to support zips.
HA-C topologies have whole new classes of metrics that are beneficial to gain insight into your cluster. A new log file, nexus_cluster.log, has been added to contain them. This log contains information about the cluster's health, such as internode latency and replication queue depth. Support zips will include this log to make introspection on the history of cluster health easier.
Additional System Status Checks for Professional HA Clusters
NEXUS-18776 , NEXUS-19313 , NEXUS-18181
System Status Checks are a great way for components of NXRM to report vital information to administrators. To that end, the checks have been added to the banner. In normal operation, every check is passing and administrators will see a green checkmark. However, if at least one status check is failing then the header will have a red exclamation point.
Three new status checks were added specifically targeting high availability health.
- Cluster Size is a new status check that ensures that your cluster has 3 nodes. If a cluster is missing a node, it can still respond to requests and save new components, but it is at risk of losing one more node and becoming inoperable.
- Transactions status check monitors an instance for any transaction with excessive retries in the last hour. Excess transactions can indicate things like heavy cluster load, inter-node network issue, or something more malignant.
- Lifecycle Phase is a status check that verifies that the node is running the proper lifecycle phase. Running in the wrong phase can occur due to startup issues, improper use of the lifecycle API, etc.
Lifecycle API
When a node becomes unhealthy, we now have a REST API to control the lifecycle phase of a NXRM node. A lifecycle phase is a step in the start up process used to group similar components and ensure that their dependencies are started before them. The REST API documentation has more information.
Maintenance API
NEXUS-18182
The Maintenace API helps NXRM administrators understand their databases' status and recover from some error cases. Each endpoint can optionally take a node Id determining on which node the request is executed. See the REST API documentation for more insights.
REST Search Improvements
NEXUS-14407
REST search now supports sorting results, as well as filtering prerelease components, allowing the search and download endpoint to return the latest version of an asset. More information in a community post.
Update packaged JRE in installers to OpenJDK
NEXUS-19619
Mac and Windows installers now include the Zulu OpenJDK 8 JRE.
Improve stability of using HA-C with Nexus Firewall
NEXUS-16852
Using Nexus Repository Manager in HA-C with Nexus Firewall could cause the cluster to have numerous concurrent modification exceptions. There were a number of changes made to both reduce the frequency of conflicts and more robustly handle them when they do occur.
Bower Resolver Updated
In addition to 3.16.0, we have also updated the bower resolver dependancies to the latest and most secure versions. We strongly recommend any users using bower update their bower resolver to the latest.
Metrics Timers Identifiers Have Changed
Some customers may be parsing the /service/metrics/data REST resource or utilizing the info/metrics.json file in support zips. This release updates our metrics library, which has changed the names of timers to include the suffix '.timer'. For example:
Old timer: com.sonatype.nexus.plugins.healthcheck.ui.HealthCheckStatusComponent.read
New timer: com.sonatype.nexus.plugins.healthcheck.ui.HealthCheckStatusComponent.read.timer
The "version" field of the metrics file reflects this change, reving the version from 3.0.0 to 4.0.0.
Audit Database Replaced With Log File
NEXUS-18813
The audit database at $data-dir/db/audit is no longer in use and is replaced with audit log files written and archived in $data-dir/log/audit . Administrators may remove the audit database files from disk at their own discretion.

We have found an issue in this release that affects NPM users, as well as using the REST search filtering by repository group names. We recommend NPM and/or REST search users upgrade immediately to 3.15.2-01 or newer.
New and Noteworthy
Beta REST API Endpoints Removed
The Nexus Repo REST API moved from beta to release status in the 3.13.10 release. The old /service/rest/beta endpoints were kept for compatibility in the 3.13.0 and 3.14.0 releases, but they have now been removed (NEXUS-18562). Update any scripts that use /service/rest/beta endpoints to use the new /service/rest/v1 endpoints.
Dynamic Storage
For our Professional licensed customers, we added a new level of flexibility for administrators when planning and updating their blob stores. Multiple blob stores can be combined into a Blob Store Group. These groups allow an individual repository to use storage across multiple locations and devices. Member blob stores can be added or removed from a group to ease the burden of migrations. Also added Fill Policies which give administrators more control and insight into how components are being stored.
For all our users (OSS and PRO) we have added Soft Quota which allow you to receive a warning when your blobstore has reached a configured metric.
OpenJDK 8 Runtime
NEXUS-6300
Users have been reporting OpenJDK has worked fine as the JVM for repository manager 3. As of 3.15.0, we now run our full test suite using a compliant Java SE standard distribution of OpenJDK 8. In light of the Oracle licensing changes to their Oracle JDK distributions, you can now be sure repository manager is fully tested against the standard.
UI Upload left files in temporary directory after upload was complete
NEXUS-18276
This bug would cause temp files to be left behind when the UI Upload feature was used. This could cause eventual disk space issues that would not be cleaned up by the standard NXRM cleanup tasks. This ticket fixes the issue going forward but does not assume to delete anything from the file system. If you utilize Upload UI frequently, we recommend checking the temp directory to see if you can get some disk space back.
Use HTTPS for outreach Base URL
NEXUS-18271
In order to promote security, we changed our Welcome Outreach capability to use HTTPS instead of HTTP.
Analytics plugin deprecated
Due to complications, the Analytics plugin and respective pages within the application have been removed from the system. If it is restored, we will have a new feature release note.
