https://github.com/DSpace/DSpace/releases/tag/dspace-4.7

More information on the 4.7 release (and the 4.x platform in general) can be found in the 4.x Release Notes.

Upgrade instructions can be found at Upgrading DSpace

DSpace 4.7 contains security fixes for both the XMLUI and JSPUI. To ensure your 4.x site is secure, we highly recommend ALL DSpace 4.x users upgrade to DSpace 4.7.

As noted in the 4.3 release notes, we also highly recommend removing any "allowLinking=true" settings from your Tomcat's <Context> configuration. Previously our installation documentation erroneously listed examples which included "allowLinking=true", while the Tomcat documentation lists it as a possible security concern.

If you are running an older, unsupported version of DSpace (1.x.x), we highly recommend upgrading to DSpace 3.6, DSpace 4.7 or DSpace 5.6 to ensure your site is secure. Per our DSpace Software Support Policy, all DSpace 1.x.x versions are now End-Of-Life.

If you are considering an upgrade from DSpace 1.x.x, note that, as of DSpace 5, your existing data (i.e. database contents, search/browse indexes) will now be automatically upgraded from ANY prior version of DSpace. Therefore, you may wish to consider upgrading directly to DSpace 5.x, as the 5.x upgrade process is simplified.

Summary

DSpace 4.7 is a security fix release to resolve several issues located in previous 4.x releases. As it only provides only security fixes, DSpace 4.6 should constitute an easy upgrade from DSpace 4.x for most users. No database changes or additional configuration changes should be necessary when upgrading from DSpace 4.x to 4.7.

JSPUI, XMLUI, REST security fixes:
- JSPUI and XMLUI
