OpenProject 16.4: Option to auto-sync system color mode

Publicado por Corinna Günther September 10, 2025 Tempo estimado de leitura: 8 minutos

OpenProject 16.4 has been released and this version introduces new features and improvements again. Aguardamos com expetativa as suas opiniões e comentários sobre as mais recentes atualizações. Tire alguns minutos para saber o que mudou para si. We will summarize the most important changes in this blog article and, as always, please see our release notes that contain all changes, features and bug fixes.

In this blog article, we will focus on two main topics: the new automatic color mode sync together with dark high contrast mode for a more convenient and accessible interface, and the PDF export of project lists for more professional reporting.

We will also briefly summarize additional important features. Aqui encontra uma navegação rápida para todas as descrições das funcionalidades:

Automatic color mode sync and dark high contrast

We always have many milestones on the roadmap, but some features stand out because they affect everyone. With OpenProject 16.4, you can enable automatic color mode sync in your personal settings. OpenProject will then match your operating system (OS) preference and switch automatically between light and dark mode. If your OS uses high contrast, OpenProject will select the corresponding light high contrast or dark high contrast mode for optimal readability.

We introduced light high contrast mode almost two years ago. With OpenProject 16.4, we now added a dark high contrast mode together with the auto-sync feature.

These different color modes are more than just convenient options. They are part of our ongoing commitment to accessibility — a principle that has been part of OpenProject from the very beginning, when the project was forked from Redmine in order to remove accessibility barriers. You can read more about this in our articles on real progress in accessibility, written by Niels Lindenthal.

By the way: When our developer Kabiru Mwenja, who is responsible for the color mode changes, demoed the auto-sync feature for the first time, the whole team was genuinely excited. This shows that even though it is a simple option, it makes a real difference in everyday work for many users.

PDF export of project lists

On the one hand, we still believe that the best way to collaborate is directly in OpenProject with living documents. On the other hand, we also know that for many organizations, PDFs remain an essential format. Whether for regulatory requirements (e.g. in the public sector), for digital or printed filing, or simply for sharing professionally styled reports with stakeholders.

This is why, over the past two years, we have continuously added PDF export features to different modules: work packages and tables, work package descriptions, meetings, Gantt charts, timesheets — and now also project lists.

With OpenProject 16.4, you can now export project lists as structured PDF reports. The export includes:

A table of contents that reflects your project hierarchy (when multiple projects are included).
A cover page and numbered sections (e.g., 1, 1.1, 1.2).
Linked section titles to jump back into OpenProject.
The same attributes and order that you configured in the list view.

To export, open the More (three dots) menu on the project list and select Export. In the modal, choose XLS, CSV, or – now also possible – PDF.

Custom fonts for all PDF exports (Enterprise add-on)

Another improvement, available as an Enterprise add-on for customers of Enterprise Basic and higher, is the ability to define custom fonts for all PDF exports. Administrators of the Enterprise Basic plan and higher can now upload fonts under Administration → Design → PDF export font. Once uploaded, the font will be used consistently across every PDF export in OpenProject — from project lists and work packages to meetings, Gantt charts, and timesheets.

This feature is particularly important for organizations with strict corporate design requirements. It ensures that all exported documents reflect the organization’s professional branding and style.

Improved meeting participants dialog

Managing participants now runs smoother: you can search and multi-select users with autocomplete when preparing a meeting, and track attendance during the meeting with simple toggles — including Mark all as attended. The dialog also aligns visually with sharing components and shows a cleaner status on the right pane and in PDFs.

Synchronize group information via OIDC (Enterprise add-on)

OpenProject 16.4 introduces the ability to synchronize group memberships from your OpenID Connect (OIDC) provider. This makes it easier to manage user groups and permissions centrally in your identity provider and ensures that memberships in OpenProject reflect those settings whenever users log in. Admins can filter which groups to import, extract name substrings, auto-create groups, and distinguish between locally managed vs. synchronized memberships.

Improved budget handling in project queries and budget planning

Budget setup is more practical: you can define a Base amount (a fixed sum) without detailing material or labor costs — and still add them later, if needed. Project lists now include planned budget, spent budget, spent percentage, and available budget for a clearer overview. We plan to continue improving budgets in upcoming releases. Read more about budgets in our user guide.

Updated Home and Project overview page

We refreshed the widgets on the Home and the Project overview pages:

cleaner styling (white backgrounds in Light mode, rounded corners, improved Dark mode support),
an always-visible More (three dots) menu,
a clearer add widgets click zone,
and a new + Widget button in the subheader that opens the selection modal and places new widgets at the top for instant feedback.
