We do hope you appreciate it and would love to hear your feedback. And of course, it is great if you find the format, in which it is presented, convenient to share.

Although the total number of contributions to the LibreOffice core has slightly dropped compared to the year before, our developers remain top code contributors to LibreOffice with 4188 code commits (32.3%). The popular Collabora Online Development Edition (CODE), for home use & small teams, saw over 70 million Docker image pulls! We are glad to acknowledge, that the move of Collabora Online to GitHub has resulted in an increased number of contributions from the community. We are truly grateful to the growing number of partners, customers and volunteers for making this work possible.

The number of worldwide Collabora Online partners has raised to 230, the Collabora Office app for Android, iOS and Chrome OS saw 500,000 installations and the last year’s joint online conference by LibreOffice and SUSE did welcome over 130 participants from all over the world.
