1.4.0 — optional cloud-folder backups
Released on latest/stable · revision 6 · November 7, 2026. Operoso 1.4.0 is the current stable release, available from the Snap Store. This is the same package accepted with an existing Google-synced folder and released to beta on November 5, promoted without rebuilding.
The working database stays local. Your sync client handles cloud upload: a local save does not confirm remote upload. No backups run while Operoso is closed. Copies are not encrypted by Operoso. This is backup, not simultaneous multi-device editing. Read the cloud-backup guide.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Operoso, simply use the following command:
sudo snap install operoso
Browse and find snaps from the convenience of your desktop using the snap store snap.
