A highly flexible version checking tool, designed specifically for modpack developers.
It can fetch JSON files containing version information from a fixed network location and notify players when there are updates.
It also displays the current and latest version information on the main interface, as well as whether an update is needed.
In addition, it can dynamically retrieve a list of sponsors from the network, JSON-formatted welcome messages, and other serializable variables.
