# NOTICE: Pending Breaking Change

# 1.3.0-rc.2 tactile-perception (2014-09-16)
The next 1.3.0 release candidate (1.3.0-rc.2) will contain a perf-related change that is likely to
introduce breakages in some applications. The change will affect filters and function call
expressions, and will not call the function if the variables passed to the function are primitive
values and have not changed since the last digest loop.
Example:
## Bug Fixes
```html
//date filter would only be called if the 'timeCreated' property has changed
<span ng-bind="timeCreated|date"></span>

## Breaking Changes
- **$parse:** due to [fca6be71](https://github.com/angular/angular.js/commit/fca6be71274e537c7df86ae9e27a3bd1597e9ffa),
all filters are assumed to be stateless functions
Previously it was just a good practice to make all filters stateless. Now
it's a requirement in order for the model change-observation to pick up
all changes.
If an existing filter is statefull, it can be flagged as such but keep in
mind that this will result in a significant performance-penalty (or rather
lost opportunity to benefit from a major perf improvement) that will
affect the `$digest` duration.
To flag a filter as stateful do the following:
```javascript
myApp.filter('myFilter', function() {
function myFilter(input) { ... };
myFilter.$stateful = true;
return myFilter;
});
