Many smallcase users have sent mails regarding the update. I have checked with smallcase and all update mails have gone.
If you are a MiLTCNX user, you have 2 stock additions
For MiMTAllCap and MiSTATH smallcase there is no change.
The Update emails are triggered only if you are invested in the smallcase and not just registered.
Any questions please write to email@example.com
