2.x.x ➡️ 3.x.x

Emails are now case-insensitive

Before 3.x.x, the local part (before the @) of the email address was case-sensitive. Therefore, king.arthur@camelot.bt and King.Arthur@camelot.bt were considered as two different users. This behaviour was a bit confusing and not consistent with 99% of web services out there.

After 3.x.x, users are fetched from the database with a case-insensitive email search. Bear in mind though that if the user registers with the email King.Arthur@camelot.bt, it will be stored exactly like this in the database (with casing) ; but he will be able to login as king.arthur@camelot.bt.

Danger

It's super important then, before you upgrade to 3.x.x that you check if there are several users with the same email with different cases ; and that you merge or delete those accounts.
