The ng-pattern validator change from 1.3 to 1.4 is not mentioned in the migration guide

[diegomrsantos]

ng-pattern directive in version 1.3.16 validates modelValue

ctrl.$validators.pattern = function(value) {
    return ctrl.$isEmpty(value) || isUndefined(regexp) || regexp.test(value);
 };

ng-pattern directive in version 1.4.14 validates viewValue

ctrl.$validators.pattern = function(modelValue, viewValue) {
    // HTML5 pattern constraint validates the input value, so we validate the viewValue
     return ctrl.$isEmpty(viewValue) || isUndefined(regexp) || regexp.test(viewValue);
 };

it's a breaking change which is not mentioned in the migration guide from 1.3 to 1.4
