+<summary>Important Notice: Backward Compatibility Break v1 -> v2</summary>
 Please note that backward compatibility is broken from Version 1 to Version 2
 due to the implementation of a more robust configuration system. In the previous
 version, user configuration consisted of a simple list of extensions with their
 associated make and run command properties. However, with the introduction of
 overlay functionality, it became necessary to add an identifier to this
 previously unnamed list, resulting in incompatibility with older configurations.

 Apologies for any inconvenience this may cause. From version 2, the plugin has been
 designed with future-proofing in mind to ensure that such issues do not recur.
