Question about v5 env variables

I am trying to move from v4 to v5 and was looking over my env variables comparing them to the v5 ones available here: invoiceninja/.env.example at v5-stable · invoiceninja/invoiceninja · GitHub

and I found a couple of variables I used in v4 which are not listed here so the question is are they no longer in use or have they been replaced by others?

#Google Maps integration
#seems to have disappeared with v5
#GOOGLE_MAPS_ENABLED=true
GOOGLE_MAPS_API_KEY=mysecretapikey

# Create a cookie to stay logged in
#seems to have disappeared with v5
#REMEMBER_ME_ENABLED=true

# Immediately expire cookie on the browser closing
#seems to have disappeared with v5
#SESSION_EXPIRE_ON_CLOSE=true

# The app automatically logs the user out after this number of seconds
#seems to have been renamed with v5
#AUTO_LOGOUT_SECONDS=1880
SESSION_LIFETIME=1800

# password for mobile app usage
#seems to have disappeared with v5
#API_SECRET=myapisecret
