One of the most exciting new features is the arrival of ONLYOFFICE Desktop Editors for ARM64 architecture .

Thanks to this, users enjoy stable and smooth performance , taking advantage of the lower power consumption and instant boot times typical of ARM processors.

For those using Ubuntu on ARM, the process is incredibly simple: just download the .deb package from the official website and run it using apt or dpkg in the terminal. Being a native version, there are no translation layers to slow down the system, ensuring that editing large documents is a smooth and enjoyable experience.

To get started, a Docker -based installation script is used , which greatly simplifies deployment. All you need is a server with at least 6 GB of RAM and a dual-core processor for everything to run smoothly. Once installed, you can manage granular permissions, allowing some users to read-only access while others have full access to edit the file in real time.

The magic of Workspace lies in its co-editing capabilities. You can choose between quick mode , where changes are seen instantly, or strict mode , where edits are only saved when you close the document or save manually. This flexibility is key when working with people in different time zones or with critical documents that require thorough review.

The system also allows for comprehensive change tracking , where you can accept or reject suggestions and browse the version history to recover deleted data. For coordination, it includes an integrated chat and the ability to connect external services like Telegram or Jitsi to make video calls while reviewing a spreadsheet.

Technical installation and server dependencies

For those who prefer manual configuration in environments like CentOS or RHEL, deployment requires preparing several components. It is essential to correctly configure the NGINX repository to manage web traffic and the EPEL repository to obtain additional packages. The PostgreSQL database is the core where the information is stored, requiring specific authentication configuration for ONLYOFFICE to communicate with it.

Another critical point is message queue management using RabbitMQ , which ensures that real-time collaboration doesn't crash. To make documents look exactly the same as in Windows, it's essential to install Microsoft fonts (mscorefonts ), thus preventing the system from replacing fonts and altering the document's layout.

Versatility and Open Source Philosophy

The suite is distributed under the AGPL 3.0 license , ensuring transparent and adaptable code. This philosophy has attracted professionals from diverse fields, from linguists to programmers, who seek a more stable tool than other open-source alternatives. The ability to connect to Nextcloud, ownCloud, or Seafile via WebDAV makes ONLYOFFICE the perfect bridge between file storage and professional editing.

By combining the power of native Office formats with the freedom of open-source software and the efficiency of ARM architecture, you get a professional, secure, and extremely flexible work environment for any type of data volume.
