Is it possible to hide the Indico version?

Hello,
Is it possible to hide the Indico version, let’s say on the home page and event page?
Thanks in advance.

If this is for “security” reasons then it’s pointless, because for a webapp that contains e.g. JavaScript bundles it’s trivial to compare them against releases to figure out which version it is.

But you can use a customization template override for footer.html where you override the indico_version block with an empty one. See here for details on customizations.
