  • Note that the system package (deb/rpm) repos deployment of Fleio will be retired (this is the last release that includes deb/rpm system packages). Deploying Fleio with docker will be the only way to run Fleio. Therefore we encourage everyone to test docker deployment in a lab environment as soon as possible.






  • In 2021.06 release we will remove the frontend customization feature. These customizations will be done entirely in Docker.
