I added a small new feature for the events : we can now specify the ending time, if we want to :)
An exemple is given on the template page.
However, for those who uses a calendar client (e.g. Thunderbird, Nextcloud, etc.), the links have changed. In order to see the ending times, you will have to re-create the calendar with the new link. But of course, it will continue to work if you do nothing ;)
