node.js express-session dependency on cookieParser

BAsed on the docs i've read so far, they recommend that i explicitly include cookieParser in my code in order for express-session to work.

however, it looks like my session code works even if i don't "require("cookie-parser". Is this because the express-session module itself includes and uses cookie-parser ?

It will work without explicit use of cookie-parser since express-session 1.5.0 (specifically since 737211b56).
