This article is intended to describe the changes post Jakarta in regards to how validation errors are displayed on the form.
Prior to the release of Jakarta, when validating mandatory fields on the form, an alert popup would appear to signal the user that there are still mandatory fields on the form not filled in.
For releases after Istanbul (that is Jakarta and onwards), a design change was made to how these validation errors would appear. These no longer appear as an alert popup but rather as an information message on the form.
