Host Updates

The host keeps itself up to date. Updates download in the background and install in a maintenance window, never during a session.

How updates work

The host checks for an update every 30 minutes.
When one is found, the host downloads it and verifies its signature straight away.
The host installs it in the update window. By default the window is 02:00 to 05:00 local time.
A session in progress holds the install until the session ends, whatever the window says.
If the new version does not start correctly, the host returns to the previous version by itself.

The host carries the same version number as the client builds, for example 2026-10-11-2304.

Windows

Settings are in HKLM\SOFTWARE\Computle\Remotle\Update. A value that is absent takes its default.

Value	Type	Default	Meaning
`Channel`	REG_SZ	`prod`	`prod` (Stable) or `beta`
`PollMinutes`	REG_DWORD	`30`	How often the host checks for an update
`WindowStart`	REG_SZ	`02:00`	Start of the update window, local time, `HH:MM`
`WindowEnd`	REG_SZ	`05:00`	End of the update window. An end before the start runs past midnight.
`WindowEnabled`	REG_DWORD	`1`	`0` installs updates as soon as they are ready, at any hour, outside sessions

The updater is the ComputleUpdater service. Updates are staged under C:\ProgramData\Computle\Remotle\Update\.

Linux

Settings are in /etc/computle/update.conf, one Name=value per line, with the same names and defaults as Windows:

Channel=prod
PollMinutes=30
WindowStart=02:00
WindowEnd=05:00
WindowEnabled=1

The updater is the computle-host-updated service. After an update it checks that the host started and registered with Computle; if it did not, the previous package is reinstalled.

The computle-enrolment package is updated with the host package rather than by the updater.

Update channel

Channel	Contents
Stable (`prod`)	The current release. Recommended.
Beta (`beta`)	New features before they reach Stable.

Any other value is treated as prod.
