We saw this week that our build and deploy process for SharePoint Framework was breaking. We tracked it down to a change in the Office 365 CLI which was released recently.

Our previous step of logging into O365 so that we can deploy out package looked like this

#o365 spo login https://blahblah.sharepoint.com

The breaking change to the CLI was that they simplified the login process (makes sense)

And now the command works without the spo precursor

#o365 login https://blahblah.sharepoint.com
