For your information,
We have just renamed the default (main) branch of
https://github.com/SuperElastix/elastix.git from "develop" to "main".
We decided to do so, especially because "main" is nowadays the default
name of the default branch, both on GitHub and on GitLab.
If you explicitly refer to this particular branch, you may need to some adjustment at your side. For example, when you locally pulled the "develop" branch of elastix, you may need to switch to the "main" branch, as suggested by GitHub:
git branch -m develop main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

Note that we already stopped using "master" as branch name, last year:

Hope this change does not cause any inconvenience to you.
Kind regards, Niels
