2026.1

Full release: https://github.com/ufal/clarin-dspace/releases/tag/2026.1
Full changelog: https://github.com/ufal/clarin-dspace/compare/sync-lindat-2025.07.16502729677...2026.1

TL;DR

• Built on DSpace 7.6.5 (security fix from 7.6.6 backported)
• Reimplemented some of the v5 curation tasks
• Enhanced provenance logging
• Health report diffs
• Personal Access Tokens (PAT) — see clarin.token.* config properties
• Backend now runs as an unprivileged user (uid 1100) — volume/bind-mount permissions need updating on upgrade
• dspace-ui.json no longer lives in the docker/ directory in the default image
• New and changed configuration properties (see table below)
• Lots of bugfixes

New / changed config properties

Property	Default	Description
assetstore.s3.enabled	false	Enable S3 assetstore
s3.download.direct.enabled	false	Issue presigned S3 URLs for downloads
s3.download.direct.expiration	3600	Expiration of presigned URL in seconds
clarin.token.encryption.secret		Required if using PAT. Generate with /dspace/bin/dspace clarin-token -g
clarin.token.max.expiration.time.in.days	90	Maximum allowed PAT expiry
config.admin.updateable.files	item-submission.xml	Array — config files updatable via the Admin API (must be bind-mounted to persist)
user.registration	false	Controls password-based user registration
versioning.submitterCanCreateNewVersion	true	Allow submitters to create new item versions
versioning.unarchive.previous.version	false	Keep previous versions archived
webui.submit.upload.required	false	Allow submitters to skip the file upload step

Upgrade notes

See the full release for step-by-step upgrade instructions. Key points:

1. Set DSPACE_VER=2026.1 in .env
2. If using FE_CMD=yarn start:dev, switch to the -dev image (see Docker Tags)
3. Fix file permissions for Docker volumes/bind mounts — backend runs as uid 1100 now
4. Review local.cfg and any bind-mounted config files
5. Run database migration and reindex Solr (discovery + OAI-PMH)
6. If running pg_dump in a cronjob — postgres no longer needs explicit port in docker compose exec dspacedb psql
