These are the instructions for people who want to test the latest version of Remmina on Fedora 20 - 26

You will obtain Remmina and FreeRDP compiled under the /opt/remmina_devel/ subdir, so they will not mess up your system too much. This is ideal for testing remmina.

You will also find the uninstall instructions at the bottom of this page.

NOTES for execution:

Gnome Shell will never show you the system tray icon and menu. Press Super+M to see the remmina icon on the message bar. Or install this extension to have full access to a remmina appindicator icon: Appindicator Support Gnome Shell Extension
XFCE and other desktop without appindicator support, will never show you the system tray icon if you are executing remmina from its compilation direcotry (~/remmina_devel/Remmina) because it contains a directory named remmina. See Bug #1363277 on launchpad
