Hi Atlassian Team,

as far as I can see there is no way to enable the flag "delete source branch" per default for all pull-requests. 

Background: some developers forget to click this checkbox when creating a pull request. After merging the source branch still exists.

It would be great if we could define "delete source branch" as default for all pull requests. So a developer has to unset it if he doesn't want to delete the source branch (which is only for some seldom cases).

Thanks

Matthias

We've added a new option to branching model settings (both at the repository and project level) allowing you to set the default value for source branch deletion on PR merge. This is now available to 100% of customers.
