Last week, we reported that Nextcloud was planning to release the first stable version of Euro-Office on June 9, aiming to offer European organizations a real-time collaborative workspace that runs entirely on open-source infrastructure.

Euro-Office, if you're not aware, is an office suite designed to break dependence on American tech giants by integrating document and spreadsheet editors directly into existing cloud platforms. The software began as a fork of ONLYOFFICE and now features active co-development by a coalition of European companies, including Nextcloud (Germany), IONOS (Germany), Abilian (France), BTactic (Spain), OpenProject (Germany), Soverin (Netherlands), and XWiki (France).
