Simple Update Checker

by Patbox

Simple Update Checker tells a modpack's players and server operators when a newer version of their modpack is available on Modrinth.

FabricQuiltClient or server, optionalGNU Lesser General Public License v3.0 onlyOpen source1.21.1 – 26.3

What it does

On clients the mod shows update information on the main screen, to the right of the modpack name and version text, and refreshes it about every hour after the game starts. On servers it writes the update status to the log after startup and shows it to operators when they join. Until an update is found, the server checks every 12 hours. Once an update is reported, the wait before the next reminder doubles each time, stopping at a ceiling of 14 days.

The check can be run by hand with the /simpleupdatechecker check command, which is limited to one refresh every 15 minutes. All automatic checks can be turned off in the simpleupdatechecker user.json config file or through the /simpleupdatechecker settings command. The mod works on Fabric and Quilt, and it is open source under the GNU Lesser General Public License v3.0 only.

Key features

  1. Main screen notice

    Update information appears on the client's main screen beside the modpack name and version text.

  2. Log and operator messages

    Servers write the update status to the log after startup and show it to operators as they join.

  3. Backoff schedule

    Repeated reminders stretch from a 12-hour interval up to a 14-day ceiling, doubling after each message, so players are not flooded with notices.

  4. Manual check command

    The /simpleupdatechecker check command runs a check on demand, with a 15-minute limit between refreshes.
