Collabora Online 25.04.4.3

Released on 22 August 2025.

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.
