Bench update, not updating frappe and erpnext?

Hi there,

i’m running bench update on developer branch, it’s updating only bench repo:

frappe@ubuntu16-dev:~/frappe-bench$ bench update
INFO:bench.utils:updating bench
INFO:bench.utils:git pull
Already up-to-date.
INFO:bench.utils:./env/bin/pip install Pillow

frappe@ubuntu16-dev:~/frappe-bench$ bench update
