Installing DSpace provides an overview of the DSpace 9 installation process and all prerequisite software. You should review this before attempting an upgrade, in order to ensure you are running the required versions of Java, Node, etc.

Upgrading DSpace provides a guide for upgrading from any old version of DSpace to v9. As in the past, your data migrates automatically, no matter which older version you are running.

Migrating DSpace to a new server provides an alternative way to upgrade by installing the new version of DSpace and migrating your existing data over.

Not yet fully updated for 10.0. This page is currently a copy of the 9.x Release Notes

10.0 Release Notes

DSpace 10.0 is a major release of the DSpace platform. It provides new features and improvements, along with bug fixes. You should be aware that all major releases may provide some "breaking changes" (major changes that may impact your local customizations).

Security Fixes

If any security fixes are applied in 10.0, they will be listed here.

New User Features

Features go here.

Breaking Changes

The following major changes may negatively impact or "break" your local customizations to prior versions of DSpace. Please be aware of them before upgrading.

Upgrade to Angular 20. This requires removing all standalone: true declarations from custom components (@Component) . If you forget to make this change, then lint checks fail during your Angular build and let you know what needs to be updated.
Rename "defaultLanguage" configuration to "fallbackLanguage". This just aligns with the naming convention for the @ngx-translate/core module that we use.

Major Updates and Improvements

Fixed a large number of other small bugs. See Changes in 10.x for a list of all changes.
Major dependency updates: Frontend updated to Angular 20. (Donated by Atmire)

Additional Thanks

Additional thanks to our DSpace Leadership Group and DSpace Steering Group for their ongoing DSpace support and advice.

Thanks also to the various developer & community Working Groups who have worked diligently to help make DSpace 9 a reality. These include:

DSpace Developers Team - This volunteer-based team leads the development of new releases. Anyone is welcome to join the Developer Meetings
DSpace Community Advisory Team (DCAT) - This team helped organize/lead the DSpace 9.0 Testathon (to bang on the system to find any last bugs), and they also provided us with advice on features, etc.

We apologize to any contributor accidentally left off this list. DSpace has such a large, active development community that we sometimes lose track of all our contributors. Acknowledgments to those left off will be made in future releases.
