The latest full release of Stackstorm (v3.8.1) has the following lines in requirements.txt:
bcrypt==3.2.0
st2-auth-backend-flat-file@ git+https://github.com/StackStorm/st2-auth-backend-flat-file.git@master
The change to require bcrypt>4.3.0 in b35830e causes a conflict, meaning that fresh installations of v3.8.1 or pack tests (which pip install as part of the script) will fail due to dependency resolution errors
