hi @DarqueWarrior
Do you plan to make the pipeline public so we can check the CI issue during the pull requests ?
regards,
Olivier

I do plan to make the build public. I just have to secure a few more keys in the build def.

[DarqueWarrior]

Your build only failed because PRs don't have permissions to change the build number which the build currently does now. I am working to change that.

Thanks for the support your changes are live now in version 4.0.6. I really appreciate it.
