Realtime Controls for Clients
Enable client message loggingAlso stores client received messages on the master.
(Pasted images are also recorded; for attachments, only the file names)
Enable auto updateEnables auto client updating.
Always match ProMaster version (new) Available only when "Enable auto update" is on.
Keeps clients on the same version as ProMaster: clients whose version differs from ProMaster are reinstalled and restarted automatically, including downgrades of clients that are newer than ProMaster.
(Use this when you roll ProMaster back to an older version and want the clients to follow. Clients act after the bandwidth-control delay (a few seconds to about a minute) once the settings are applied; a client that has a send/receive window or the LogViewer open, or a file transfer in progress, waits until those are finished.)

Notes:
 - If ProMaster's own auto update is left enabled, ProMaster will be upgraded to the latest version again and the clients will follow. Disable ProMaster's auto update as well if you want to pin a version.
 - Clients are never downgraded to a version with an older log DB format (no such version exists as of v5.8.6).
 - Only clients that support this option (v5.8.6 or later) follow downgrades; older clients only upgrade as before.
 - If ProMaster itself is rolled back to a version without this option, the setting is carried over and remains in effect. Turn off "Enable auto update" to stop it (turning it on again also re-enables this option).

Prohibit receiving messages from free versionProhibits receiving messages from the free version
Prohibit send/recv with free version & hide/deactivate userlist This will block sending and receiving messages with the free version. It will also prevent free version users from appearing in the Pro version's user list.
(Free version users who have appeared in the past will be displayed as inactive for about two weeks (from the start of the ban). To hide them immediately, select the user in the Send Window, right-click → Priority Settings → Remove from User History List.)
Note that it is not possible to prevent some Pro version users from appearing in the free version's user list. (However, sending and receiving will not be possible.)

(Traffic may increase for several tens of seconds after switching, so frequent switching is not recommended.)
