With the version number the plugin can check or exact version number or
it can peform test for "version x.x.x or higher" or whatever else is necessary.

See my example:

/*--- version ---------------------------------------------------------------*/
G_MODULE_EXPORT const gchar version[] = PLUGIN_VERSION;

/*--- plugin_init -----------------------------------------------------------*/
G_MODULE_EXPORT void plugin_init(plugin_address_table_t *pat) {

  /* initialise the table of pointers needed in Win32 DLLs */
  plugin_address_table_init(pat);

#if CHK_VER  /* 0.10.5 or later */
  if (strcmp(epan_version, VERSION)) {
    g_error("HiPath plugin: %s\n"
            "Plugin is compiled for Ethereal %s but running version is %s",
            version, VERSION, epan_version);
    return;
  }
#endif
