Collabora Online 25.04.4.3

Released 22/08/2025

New Features

  • Handle links in PDF documents like in other document types.
  • OpenShift compatible Docker images – use libnss-wrapper to create `/tmp/passwd` with random UID assigned by OpenShift and make libc use this `/tmp/passwd` file. This works around the problem that coolwsd expects to run as its internal cool user and to manage child roots, cache and config file under directories owned by that user but OpenShift’s restricted SecurityContextConstraints (SCC) assign a random UID at runtime.
  • New WOPI CheckFileInfo property: UserCanOnlyManageRedlines . If set to “true”, a specific feature-restricted mode is activated, which is similar to read-only mode, but allows the user to see and manage tracked changes: accept / reject / comment on them. This implies “UserCanWrite”.
  • Added editing support to JSDialog’s treeview widget.

Collabora Online 25.04.2.3

Released 19/06/2025

Major release of Collabora Online. Please find all details in the 25.04 announcement.

  • We have updated our PGP signing key for COOL and CODE .rpm and .deb packages to align with modern standards. This change is necessary as some recent Linux distributions have migrated to Sequoia-PGP for key and signature verification.
    • Action required:
      Users will need to update the Collabora Online PGP key on their systems. This can be done using the following commands:
      • On RPM based distros:
        wget -O repomd.xml.key https://collaboraoffice.com/repos/CollaboraOnline/CODE-rpm/repodata/repomd.xml.key && sudo rpm --import repomd.xml.key
      • On DEB based distros:
