Firebase: site not updated after doing firebase deploy

I just migrated my Firebase project to the new console (now it is firebase.google.com)

But after running firebase deploy, I found that the files are not updated, it says

starting release process (may take several minutes)...

✔ Deploy complete!

but nothing changed on my site.

Can we deploy website on Firebase?

Firebase Hosting is production-grade web content hosting for developers. With a single command, you can quickly deploy web apps and serve both static and dynamic content to a global CDN (content delivery network).

Actually it took some time for the first deployment after migration.

make sure you're building any new changes you've made, so if you have an angular 2 application and are using the cli type ng build then firebase deploy
