This page relates to the release notes of Nuxeo Server and related addons for LTS 2025 cycle. It will list the improvements and features that are successively shipped with the 2025.x releases.

What's New in LTS 2025.22 / LTS 2025-HF22

Support AWS DocumentDB Elastic

Improve support of AWS DocumentDB Elastic.

Allow Disabling Thumbnail Auto-Generation Per Repository

Thumbnail auto-generation can now be disabled globally or per repository.

Optional thumbnail auto-generation

• Set nuxeo.thumbnail.enabled=false in nuxeo.conf to disable it globally.
• Contribute to the new thumbnailConfiguration extension point of org.nuxeo.ecm.core.api.thumbnail.ThumbnailService for per-repository overrides:

<extension target="org.nuxeo.ecm.core.api.thumbnail.ThumbnailService" point="thumbnailConfiguration">
  <thumbnailConfig repository="other" enabled="false" />
</extension>

When disabled, no thumbnail is computed at document creation. Thumbnails on documents that already carry the Thumbnail facet continue to be refreshed when their main blob changes.

The perf server template now ships with thumbnail auto-generation disabled.

Purge existing thumbnails

A new bulk action and management endpoint allow removing stored thumbnails (blob + Thumbnail facet) for documents matching an NXQL query.

• DELETE /api/v1/management/thumbnails/remove?query=<NXQL>&queryLimit=<N>
• Both parameters are optional. Default query targets all non-proxy documents currently carrying a thumbnail blob.

Refactor PublicationJsonEnricher to Use a Page Provider

PublicationJsonEnricher now uses the SearchService. The 2025 branch use SearchService.search() directly. A new page provider plugged into the Elasticsearch backend has been introduced for the 2023 branch. For additional information, see Upgrade notes.

Take Into Account the Search Pattern on LDAP Directories

The UserGroup.Suggestion operation now honors the directory's substringMatchType (subinitial, subany, subfinal), so LDAP user/group suggestions return infix and suffix matches when configured to do so.

Support DocumentDB Local

Improve support of DocumentDB local docker image.

S3 Blob Storage Properties With Full nuxeo.s3storage.* Prefix Cannot Be Set via Framework Properties (nuxeo.conf)

"nuxeo.s3storage.multipart.upload.threshold" and "nuxeo.s3storage.minimum.upload.part.size" are now properly taken into account.

Expose Relevance Score via Enrichers

There is a new score enricher to get the fulltext score in PageProvider results.

Security Fixes
