At the recent Open Source Conference 2025 in Luxembourg there were two talks about LibreOffice.

The first was Lessons learned from 13 years at The Document Foundation and LibreOffice, where Florian Effenberger, Executive Director of the foundation, talks about the legal setup of The Document Foundation and how its statutes enshrine values and ideals like openness, transparency and meritocracy.

Then there was Open Innovation and Open Source in Schleswig-Holstein – Practice for Europe, where Sven Thomsen, CIO of the German federal state of Schleswig-Holstein (which is moving to LibreOffice), outlined the state’s pioneering path toward digital sovereignty through Open Source and Open Innovation. The talk highlighted the risks of dependency on proprietary software—including lack of transparency, inflated costs, and reduced security.

LibreOffice at LinuxDays 2025 in Prague

LibreOffice stand at LinuxDays 2025

On October 4 and 5, the LinuxDays 2025 event took place at the Faculty of Information Technology (Czech Technical University). It combined stands for free and open source software projects with workshops and talks, and the LibreOffice community was there, represented by Zdeněk Crhonek, Petr Valach, Stanislav Horáček and Mike Saunders.

At the stand, we had flyers explaining what LibreOffice is and how it can be used in various contexts (homes, businesses etc.) along with stickers, beer/coffee mats, and printed versions of the handbooks, to show how extensive the documentation for LibreOffice really is. We also had a fun quiz for participants to try.

LibreOffice stand at LinuxDays 2025

During the two days, many visitors came to our stand, gave feedback and asked questions. Of course, at an event focused on Linux, most visitors already knew what LibreOffice is (and many used it regularly). But they gave us some useful feedback and asked about new features, including:

  • Where is the online version of LibreOffice?
  • Better clipboard management (normally handled by the operating system)
  • More development of Base (TDF has a new paid developer role for this)
  • Better options for copying and pasting in Calc
  • Real-time collaboration would be good
  • Clearer warnings about formatting problems when opening Microsoft Office documents
  • Simplify the user interface, using OBS as an example
  • Integrate text translator directly into Writer and Calc
  • It would be nice to have an optional automatic cloud saving feature
  • Make the tabbed user interface default
  • Functions in Calc for interpolating and extrapolating values in 2D and 3D tables

Anyone who wants these features or improvements in LibreOffice is welcome to join our project and help to make it happen, or fund a developer. And we plan to be at more events in the coming months – stay tuned to this blog and our Mastodon account for news!

Outcome and conclusions of the VI Latin American LibreOffice Congress

Gustavo Pacheco send us this report on the activities of the sixth edition of the Latin American LibreOffice Congress, held in Habana, Cuba, from October 6 to 9, 2025:

With a completely different organizational model than in previous years, our conference was held as a prominent section within another broader event: the Cibersociedad 2025 congress.

Held every two years by the Union of Computer Scientists of Cuba, Cibersociedad aims to be a space for innovation and proposals for the construction of a more sustainable and equitable digital future.

For the events in 2019 in Asunción, 2022 in Brasília and 2023 in Mexico City, we had the support of universities, and in 2024 in Montevide, support local communities. But 2025 marked a new moment for the Latin American organizing committee. On this occasion, our relationship was established with an organization of professionals, the UIC, which contributed all its knowledge and structure to the planning of a joint event.

The idea arose from the proposal of the president of the UIC in 2023, Ailyn Febles, who, in contact with Gustavo Pacheco, presented the invitation to hold the conference in Cuba, motivated by the legacy left by Carlos Parra (1961-2022), an active member of both the UIC and theTDF.

As in 2023 we already had our congress confirmed for Mexico City, we would talk again during that year to align the possibilities.

In addition to the excellent event in Mexico City, at that time we also had the Montevideo congress. That one was an atypical event, as it was carried out as a contingency to the originally planned place, the state of Rio Grande do Sul, in Brazil, affected by the largest flood of the century in May 2024. The event was only saved from being canceled thanks to the support of the Uruguayan community. Thus, for the first time, the congress was held in a public space outside a university: a challenge also for local volunteers.

We did not reach the expected face-to-face audience, but we had a meeting with exceptionally high-quality participations. With the participation of Gastón Hannay in the graphic design activities, we achieved the objective of the congress to always bring, as a minimum, a new permanent volunteer for the project, in addition to interesting results from the participation among the members, such as the development of new formulas for Calc, by Xisco Fauli, based on the presentation of the practical experience of Ismael Fanlo with spreadsheet users.

With the results of 2024, we began planning for 2025 based on the premise of taking advantage of our participation in the event to visit universities, public institutions, third sector entities, local communities, etc., in their own organizational spaces. This idea was very well received by the then new president of the UIC, Omar Correa.

The initiative would also fit the way the event would be carried out. By incorporating our event into a larger one, we obtained the benefit of reducing the workload, however, we no longer had total autonomy in defining the programming. This year, we had a smaller number of speakers, none of them from Asia, which, as far as possible, we intend to improve in future editions.

In fact, since Cibersociedad is a broad event, the LibreOffice project programming was concentrated on the opening day, October 6, and in the special session “LibreOffice Congress and Technological Sovereignty”, on the 8th. With the remaining days available, we articulated a parallel agenda of activities, with visits and strategic meetings with managers and professionals from governmental and community areas.

Opening Session

We started Cibersociedad 2025 with Gustavo Pacheco representing the LibreOffice project in the Opening Session, together with the Minister of Communications of Cuba, Mayra Arevich, the president of the UIC, Omar Correa, the representative of the Central Committee of the PCC, Omar Pérez Salomón, and the president of the Scientific Committee, Tatiana Delgado.


Opening Session Cibersociedad 2025

Immediately after the opening session, we had our first strategic meetings.

In addition to welcoming, the Minister of Communications of Cuba, Mayra Arevich, showed interest in the implementation process of LibreOffice by the Government of Mexico, presented by Adlair Cerecedo. Subsequently, the importance of the participation of the LibreOffice project in Cuba became even more evident with the publication of the minister in her profile after the conference of Olivier Hallot on LibreOffice and the most important aspects of the migration process. Through the minister, we were also received by the general director of the Joven Club project, Maidelys Pupo, on October 9.

It was also the moment to personally meet Professor Joaquín Pina, from the UIC of Havana. Professor Pina will be the focal point of contact for the Cuban community. On the initiative of Pina, Hanoi Calvo and Liber Luis González, an online group was formed with students and professionals linked to the UIC. This working group will aim to study and develop extensions for LibreOffice, with possible results for the next FLISOL, the most important decentralized Free Software event in Latin America, in April 2026.

We also had long conversations with the LPI representative in Latin America, Juan Ibarra. Ibarra is Paraguayan and already participated in a LibreOffice Conference in 2021. Through Juan, we were able to learn about LPI’s strategy for the Cuban market, which involves both the UIC and the universities.

Finally, the rector of the University of Computer Sciences (UCI), Raydel Montesino, informed us about the itinerary prepared for the visit to the UCI the following day.

Visit to the UCI

On October 7, our agenda was completely focused on the visit to the University of Computer Sciences (UCI).

To make the meeting possible, our request was:

  1. to know the University, its courses, the profile of its faculty and students, and its relationship with Free Software projects;
  2. hold a meeting with the members of the University’s board of directors, to assess the possibility of a joint long-term collaboration;
  3. present LibreOffice to the students, preferably to those who had some relationship with free software projects.

After a 30 km journey from Havana, we arrived at the UCI, where we were received by the director of International Relations, Delly Lien González. The university has an infrastructure of more than 150 buildings, distributed in 268 hectares. Over 21 years, it has trained more than 16,800 engineers and technicians. The UCI is also the headquarters of Nova Linux, the reference Linux distribution in Cuba.

After the detailed presentation, we were invited to a meeting with the administration professors and the Nova Linux developers. In our presentation, we highlighted our interest in spreading LibreOffice in universities through the exchange of our knowledge and, in the case of the UCI, stimulating the formation of a study group focused on LibreOffice that can meet the needs of local users, based on the Nova Linux team. For its part, the UCI highlighted the technical training of the university and that yes, there is interest in this type of collaborative action, which we should detail in the coming weeks.


Meeting LibreOffice Latin America, UCI Board of Directors and Nova Linux.

Our next activity was a technical presentation for the UCI students. Xisco, Olivier, Mauricio and Adlair gave a presentation and then Gustavo spoke about the main topics of the Latin American LibreOffice Congress held in Cuba and the reasons for the visit to the UCI.

At the end of the visit, after the photo with the group, professors Ailyn Estrada and Serguey González presented us with copies of the book Good Practices for Migration to Open Source, a UCI publication that very well illustrates the history and importance of open technologies in the institution.

Special Session – LibreOffice Congress and Technological Sovereignty

The third day of the event was dedicated to our programming with additional panels related to Free Software and Technological Sovereignty.

Within our space in the programming, we organized the presentations differently than in other years. On this occasion, apart from the initial introductory conference by Olivier, the topics were divided into panels with two speakers each. In this way, despite the breadth of the content, the dynamics of the activities were attractive to the participants:

Conference LibreOffice and the liberation of digital imperialism, Olivier Hallot


Olivier Hallot opens the special session of the LibreOffice project in Cibersociedad 2025

The first conference, proposed and presented by Olivier, was very important to update the knowledge of the public present. Through a clear presentation, Olivier mentioned the main characteristics of the product and the project, highlighting important topics related to the event, such as technological sovereignty and access to knowledge.

Panel Migration of the LibreOffice suite and the project of the Government of Mexico, Olivier Hallot and Adlair Cerecedo-Méndez

Next, Olivier led the transition of the topic to the migration process to LibreOffice, where Adlair presented the details that, today, qualify the Mexican project as one of the most important projects in progress, not only in Latin America, but throughout the world.

Panel “Opportunities and Connections for the rebirth of the Cuban LibreOffice community”, Gustavo Pacheco and Mauricio Baeza

This panel originally had a propositional structure in which ideas for the reorganization of the Cuban community would be presented. However, the first days of activities in Havana were so intense that Gustavo and Mauricio decided to modify the focus of the panel and mention the results already achieved, among which are:

  • the work agenda proposed by Joaquín Pina focused on Flisol 2026;
  • the visit to the UCI and the possibility of collaborative projects with LibreOffice and Nova Linux;
  • the common interest between the technological projects of Cuba and Mexico with the support of the community;
  • the surprises related to the interactions of the event, such as the interest in the LibreOffice Training Certification, motivated by the presentation of Professor Yusniel Valdés, from Pinar del Río, on the use of LibreOffice for the teaching of computer science in primary and secondary schools in Cuba.

The example of the Brazilian community was also mentioned, through the four basic aspects to stimulate volunteer work: regular online meetings, friendly environment, clear and objective tasks and tutoring of the most experienced. Mauricio contributed the Mexican experience, detailing the importance of the 2023 conference and the LibreOffice project in the Social Service: the period in which young Mexicans carry out volunteer work with mentoring for a few months for the benefit of society in general.

Panel “Technical visions of the LibreOffice project: Quality Control and Extensions”, Xisco Fauli and Mauricio Baeza

Xisco Fauli began his presentation with an introduction to quality control, highlighting the collaborative tasks that provide the new volunteer with a quick technical understanding of the project.

Mauricio Baeza presented the development of extensions in LibreOffice with Python. This was a strategically important presentation for our event due to the interest shown in the group that Professor Joaquín Pina will coordinate.

Practical workshop: Show me code!, Olivier Hallot and Xisco Fauli

Olivier and Xisco finished the day repeating the technical presentation they had made the day before at the UCI. A technical introduction to LibreOffice with the main aspects of the development process, talking about the knowledge requirements, the infrastructure and the support resources of the project.

Joven Club

Taking advantage of the proximity, we visited the central headquarters of the Joven Club, in the central area of Havana. The general director of the project, Maidelys Pupo, explained to us that the Joven Club is a public organization with its own financing, created by Fidel Castro with the aim of implementing teaching centers in the areas of robotics, electronics and computer science for young people. In total, the Joven Club has more than 600 facilities in hundreds of Cuban cities. The biggest challenge today, according to Maidelys, is the infrastructure. There are difficulties in updating the equipment park. Even the simplest maintenance tasks take longer than expected.

Later, the director of national computerization, Lexy Gaspar, joined us, who detailed the projects in progress, despite all the difficulties derived from the current economic situation in Cuba. Due to its capillarity throughout the country and for being a technical training center, the structure of the Joven Club is used by companies and government agencies for teaching and support in the area of technology.

Final outcome

The day after the closing of the congress was dedicated to evaluating the results, before the participants began the return trip. In general terms, the experience was very positive. After months of organization and planning work, we can affirm that the Latin American LibreOffice Congress has fulfilled its objectives. We spread the knowledge of the project, consolidated institutional relations and recovered the legacy of our member Carlos. We have excellent possibilities to continue with the growth of the local community of the LibreOffice project in Cuba, either by individual or institutional initiatives.

As a secondary result, the importance of the Mexico migration project became evident. This was one of the motivations why we received the invitation from Manuel Haro, from the Gnome Latam project, to participate in the CCOSS + Gnome LATAM Conference, on November 21 and 22 in Aguascalientes, Mexico.

As for the future, for the next editions, the same formula for success this year can be repeated.

Leaving the event space and presenting LibreOffice where users and potential collaborators are was fundamental to our success. We are not yet sure where the next edition will take place, but Bolivia, Chile and Colombia, in that order, emerge as possibilities. Whatever the place and the model, our event will continue with the objective of bringing, in the best possible way, the LibreOffice project to the local communities of Latin America.

🇨🇺 LibreOffice in Latin America: heading to Havana for the 2025 Latin American Congress

From October 6 to 9, Havana, Cuba, will host the Latin American LibreOffice 2025 Conference, a meeting that will bring together contributors, developers, universities, and governments from the region to celebrate and strengthen free software.

This year, the Latin American conference will be held as part of the IV International Congress on Digital Transformation (Cibersociedad 2025) in Havana, Cuba. This integration reinforces LibreOffice’s crucial role in the digital transformation of Latin American communities, promoting open innovation, technological sovereignty, and collaboration between countries.

The event will take place at the iconic Hotel Nacional de Cuba and will feature an intense program of lectures, panels, and workshops dedicated to LibreOffice, its communities, and institutional adoption initiatives.

🌍 A meeting that connects communities and governments

The opening ceremony will pay tribute to Cuban volunteer Carlos Parra, who passed away in 2022.

It was thanks to his dedication, articulation, and love for the community that the opportunity arose to hold the Latin American LibreOffice Congress in Cuba—a dream he helped make possible.

Carlos was the link between the Cuban community and The Document Foundation, and his contribution will remain as a legacy of collaboration and commitment to digital freedom.

During the event, Adlair Cerecedo-Méndez will present the experience of Office GobMX, the LibreOffice-based suite developed by the Mexican government. Other highlights include the panel “LibreOffice is freedom,” with Olivier Hallot, founding member of The Document Foundation and Documentation Coordinator for the LibreOffice Project, as well as discussions on government migration, extensions, technical quality, and the rebirth of the Cuban community — with participation from Gustavo Pacheco (Brazil), Mauricio Baeza (Mexico), and Xisco Faulí (Spain).

🧑‍🏫 Training and academic innovation

At the University of Information Sciences (UCI), the event will open space for young people and educators with the “LibreOffice and Universities” lab, led by Gustavo Pacheco, and the “Creating my first extension” workshop, conducted by Mauricio Baeza — a practical opportunity for those who want to learn how to expand LibreOffice and contribute technically to the project.

💬 Regional meetings and plans for 2026

The congress will close with meetings between Latin American members of the LibreOffice community, addressing:

  • the 2026 events calendar (including esLibre and the next Latin American Congress);
  • academic projects such as Google Summer of Code and Outreachy;
  • and new partnerships with other free software communities, such as GNOME Latam.

These sessions reflect the collective commitment to strengthening collaboration between countries and consolidating a more active presence for Latin America within The Document Foundation.

💪 An event driven by volunteers

The Congreso Latinoamericano de LibreOffice is an event organized entirely by volunteers, who dedicate their time, energy, and knowledge to make this initiative possible. Our special recognition and thanks go to Daniel Rodriguez (Argentina), Gastón Hannay (Uruguay), Omar Correa (Cuba), Gustavo Pacheco (Brazil), and Juan González (Mexico), who have been working tirelessly to make every detail of this edition possible.

We also express our sincere gratitude to the University of Computer Sciences (UCI) and the Cibersociedad 2025 organization for opening their doors and sharing their infrastructure—including rooms, laboratories, and technical support—making it possible to hold the Latin American LibreOffice Congress within their event.

This partnership reinforces the spirit of academic collaboration and the joint commitment to digital transformation in Latin America.

The Document Foundation (TDF), in its mission to promote LibreOffice and strengthen its global community, supports and sponsors these activities, enabling the participation of volunteers from different countries.

This support allows members of the Latin American community to meet in person, exchange experiences, and strengthen the international collaboration that sustains the project.

🌎 Freedom, collaboration, and the future

The LibreOffice Latin American Congress in Cuba is more than a technical event—it is a reunion of the Latin American community, united by ideals of freedom, solidarity, and technological sovereignty.

LibreOffice is, above all, a project made by people, for people. And this congress is living proof that collaboration can cross borders, languages, and generations.

📅 Date: October 6-9, 2025
