Seems like Bench Repo has Lost the Develop Branch?

Hi,

I tried to run bench update on my test environment and got an error:

aditya@erpnext:~/frappe-bench$ bench update --no-backup
INFO:bench.utils:updating bench
fatal: Couldn't find remote ref refs/heads/develop
Traceback (most recent call last):

    raise CommandFailedError(cmd)
bench.utils.CommandFailedError: git pull

On further analysis, I found out that the develop branch has been removed from bench repo is this deliberate or by mistake?

Seems like it. The develop branch mostly helped in maintaining the differences between 6 and 7, now that 7 is out, develop has been merged into master and deprecated.
