Sonatype Nexus Repository 3.48.0 Release Notes
Released February 27, 2023
Content Replication In this release, we introduce a simpler, more straightforward way to make your artifacts readily available across distributed teams: content replication. With content replication, you can manage what binaries are copied from one instance and pre-emptively pulled via HTTP to other instances. Upgrade Impacts for Those Using PostgreSQL Databases After upgrading to 3.48.0, those using an H2 or PostgreSQL database will need to run a task for each existing Apt, Helm, and Yum repository in order to rebuild their metadata. |
New and Improved Content Replication PRO
In 3.34.0, we introduced our first replication feature, which used a manually run replicator tool to copy binaries from one blob store to another. We've learned a lot since our initial replication release, and we've gratefully received and listened to your feedback.
In this release, we introduce a simpler, more straightforward way to make your artifacts readily available across distributed teams: content replication
With content replication, you can manage what binaries are copied from one instance and pre-emptively pulled via HTTP to other instances.
New assets are published to the Sonatype Nexus Repository source instance
The replication task runs on the target instance on a schedule (each minute) to identify new assets
The replication task issues proxy requests for each new asset to replicate them to the target instance
Users on the target instance now have access to newly added artifacts on the target instance
There are multiple ways you can use content replication, including having multiple targets proxying one source, bi-directional content replication, or replicating a subset of content. You can learn more about these use cases and how to configure them in Content Replication Use Cases and Scenarios.
Content replication removes the requirement for manually running a separate replicator tool. It is far easier to configure and automatically runs every minute (or on your desired schedule as configured).
Content replication also has a shorter list of prerequisites and supports more formats!
Sonatype Nexus Repository Formats | Legacy Replication | Content Replication |
|---|---|---|
Apt |  |  |
Docker | | |
Helm | | |
Maven | | |
npm | | |
NuGet v3 | | |
R | | |
Raw | | |
RubyGems | | |
Neither content replication nor legacy replication support Cocoapods, Conan, Conda, Git LFS, Go, p2, PyPI, or Yum formats
We cover this fully in our content replication documentation; however, if you're looking to reduce latency and make your content available to distributed teams quickly and efficiently, then we designed content replication with you in mind. Follow the simple content replication setup procedure to get started today!
Content replication is not appropriate for disaster recovery. If you need a disaster recovery solution, please see our resilient deployment options and backup and restore procedures.
While help documentation for legacy replication remains available, it will be unavailable for general use, and we will eventually remove it. Reach out to your CSE if you are still using legacy replication and would like to continue using it.
Improved NuGet v2 Performance on PostgreSQL PRO
In this release, we made pagination performance improvements for NuGet v2 repositories on deployments using a PostgreSQL database. After upgrading to 3.48.0, users can expect pagination in NuGet v2 repositories to improve so that retrieving a page takes only milliseconds rather than multiple seconds.
Notable Upgrade Impacts
After upgrading to 3.48.0, those using an H2 or PostgreSQL database will need to run ataskfor each existing Helm and Yum repository in order to rebuild their metadata:
Helm - Rebuild Helm metadata for each Helm repository
Repair - Rebuild Yum repository metadata (repodata) for each Yum repository
Bug Fixes | Description |
|---|---|
NEXUS-36573 | Creating new repositories no longer triggers a complete Helm index rebuild for those using OrientDB. |
NEXUS-36998 | Improved performance of NuGet v2 |
NEXUS-37617 | Fixed an issue that was causing UI latency when loading welcome page in some circumstances. |
