2020 Release Notes

2020-12-24

A flaw ( NEXUS-26251 ) has been discovered in Cleanup Policies affecting version 3.29.1. Repositories with a cleanup policy can have components soft deleted that do not meet the criteria specified.

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:

Blobstore, Docker, Scheduled Tasks

[NEXUS-25504] Unable to pull images from hosted docker repo after move to new blob store

helm

[NEXUS-25611] Installing via helm proxy errors if not using official remote

npm-audit

[NEXUS-25936] npm audit fails with 500 response using group and anonymous

NuGet V3

[NEXUS-25801] Group repository registration API requests may fail

Staging

[NEXUS-24391] 'Destination already contains component' error when using staging API

2020-12-04

Sonatype recommends that administrators running 3.28.1 and earlier upgrade immediately.

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.

[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.

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.

[NEXUS-25506] New installs will now contain the default NuGet proxy repository as https://api.nuget.org/v3/index.json. 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 (https://www.nuget.org/api/v2/).

[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.

[NEXUS-25307] Protection against deletion of related blob stores while the Change repository blob store task is executing

[NEXUS-14631] Added more attributes to REST resource for asset

[NEXUS-19021] Logging at default levels when roles are added or removed

[NEXUS-25628] yum metadata missing provides entries when multiple versions are provided by a package

2020-10-19

[NEXUS-25507] Fixed an issue that caused the Change repository blob store task to spawn too many threads.

2020-10-01

[NEXUS-25099] Group Deployment will provide Nexus Repository Pro users a single URL (Group Repository) to push and pull npm packages with development CI build tools. This new feature delivers frictionless ecosystem support for developers as Group Deployment for npm replaces the need to know the various URLs for individual repositories.

To start using Group Deployment for npm, check out the setup and configuration details and start enjoying reduced storage and easier client and reverse proxy configurations.

A flaw [NEXUS-25507] was discovered in the Admin - Change repository blob store task that may cause NXRM 3.28.0 to crash. Users of this task are strongly advised to update to version 3.28.1 or newer.

[NEXUS-12016] The Change Repo Blob Store feature allows an administrator to migrate the component binaries of a repository from the current blob store to a different blob store. Administrators can now manage the mapping of repositories to blob stores even after they were initially configured.

The benefits include:

[NEXUS-25162] org.sonatype.nexus.repository.storage.WritePolicy has been moved to org.sonatype.nexus.repository.config.WritePolicy. This will impact any Groovy scripts using the org.sonatype.nexus.script.plugin.RepositoryApi to create repositories.

[NEXUS-25209] Any scripts or third-party plugins using org.sonatype.nexus.repository.storage.TempBlob must change to use of org.sonatype.nexus.repository.view.payloads.TempBlob.

[NEXUS-25336] We've replaced the Google Guava Java supplier on our APIs, so people consuming or implementing them will need to update those usages to java.util.function.Supplier.

If you are upgrading or configuring NXRM to use a direct HTTPS connector, you may need to adjust the default etc/jetty/jetty-https.xml configuration file to successfully start NXRM. The symptoms and the adjustments to make to start NXRM 3.26.0 are outlined in NEXUS-24867.

[NEXUS-24788] Following the previous releases, we have added support for 4 additional formats to both the Import and Export tasks. Together with Maven, Raw, npm, and NuGet support, you can now:

Import directly from Nexus Repository Manager v2

Move components of these formats between Nexus Repository Manager v3 instances

[NEXUS-23550] proxy repository does not work with some sites

2020-06-08

[NEXUS-23854] Export enables customers to export Raw and Maven contents from any repository to a target folder. The exports can then be imported into another repository in the same instance or a different instance. This is a great way to migrate content between two or more Nexus Repository Manager Pro 3 installations. Future releases will include additional support for NuGet, npm, RubyGems, Yum, Docker, and PyPI.

To use Export, configure the task from Settings → Tasks → Create Task → Repository - Export assets

[NEXUS-23970] NuGet V3 Hosted support gives Nexus Repository users access to the up-to-date V3 API. This is the second part of a wider initiative to bring full V3 support (Proxy, Hosted, and Group). Group repository support will be the final stage in an upcoming release.

Several new and improved REST endpoints are in this release. See the below tickets for specifics including upgraded Blobstore, Atlassian Crowd, and Nexus IQ endpoints. New REST endpoints have also been released including CocoaPods, Maven Group, Raw, and RubyGems repositories.

[ NEXUS-23926 ]License API out of beta

[ NEXUS-23929 ]Routing Rules API out of beta

[ NEXUS-23897 ] Memory settings in the docker image standardized to our recommended minimums

This changes default memory allocations from 1200m to 2703m as well as a larger heap. If your instance cannot handle these settings you may need to make manual adjustments but be aware your instance is likely under-resourced in this case.

[ NEXUS-23870 ] "Node already has an asset" for browse tree rebuild no longer fails Transactions status check

[NEXUS-23903] Long-running database queries for Docker repositories can lead to thread and db connection pool exhaustion performance

2020-05-05

[NEXUS-23853] In Nexus Repository Manager 3.23.0, we focus on importing content from an external source and for a subset of formats. This can help customers migrate content from Nexus Repository Manager 2 to Nexus Repository Manager 3 at their own pace.

Import is implemented as a task. You can configure the Repository - Import external files task from Settings → Tasks → Create Task

[NEXUS-16954] We are excited to announce enhanced Javascript support with Nexus Intelligence via npm audit for Nexus Repository Manager. Nexus Intelligence via npm audit will allow developers to check for policy violations in their Javascript projects, using the npm audit command built into the npm CLI, coupled with the precise data of Nexus Intelligence. Running the npm audit command lists all known vulnerable dependencies from your package.json file while gaining the benefits of the most precise intelligence regarding security vulnerabilities, license risk, and architectural quality of open-source components.

This feature will be available to both Nexus Repository OSS and Pro users and will require a license of Nexus Firewall or Nexus Lifecycle (Nexus IQ version 89 and above). Nexus Repository Manager admins can enable Nexus Intelligence via npm audit across all development teams without having to modify any setup on the developers’ machines.
