- The Pod API field `.spec.schedulingGates[*].name` now requires qualified names (like `example.com/mygate`), matching validation for names of `.spec.readinessGates[*].name`. Any uses of the alpha scheduling gate feature prior to 1.27 that do not match that validation must be renamed or deleted before upgrading to 1.27.

"messageExpression declares a CEL expression that evaluates to the validation failure message that is returned when this rule fails. Since messageExpression is used as a failure message, it must evaluate to a string. If both message and messageExpression are present on a validation, then messageExpression will be used if validation fails. If messageExpression results in a runtime error, the runtime error is logged, and the validation failure message is produced as if the messageExpression field were...

  
  If `username.expression` used 'claims.email', then 'claims.email_verified' must have been used in `username.expression` or `extra[*].valueExpression` or `claimValidationRules[*].expression`. An example claim validation rule expression that matches the validation automatically applied when `username.claim` is set to 'email' is 'claims.?email_verified.orValue(true)'.
