in O365 Sharepoint, do I have to re-create Sharepoint Library templates periodically?

[HermionesSlave]

If a Sharepoint Library Template remains valid for all the Library settings I need, do I have to re-create that Template periodically in order that any Libraries created from it remain up-to-date and valid?  I can understand re-creating a Template when the Library parameters have changed, but in this circumstance the Library Template has remained constant for months.  Am I right in thinking that, even if the Template is 'old' any subsequent Library created from it will be 'updated' automatically by O365?
