Hello
for a better effect and to align the double points, make this change:

	<MSGID_VERSIONCURRENT content="Versión actualmente instalada&#x9;:"/>
	<MSGID_VERSIONNEW content=" &#xD;Última versión disponible&#x9;:"/>

You can also put 5.3.0 for the version which will differentiate the future versions
Regards
