If you are running Spigot, Paper or BungeeCord on your server, it is advised that you keep your JAR files up to date as patches and bug fixes are released on a regular basis.
You can update your server to the latest build available:
1. Stop your server
2. Delete the /jar directory (see knowledgebase article Using FileZilla for FTP File Management)
3. Start your server
This will force your server to grab the most recent build for the version you have selected.
