> Some behaviors have been changed, as these are patches of incorrect behaviors this is still being considered a patch release, however if you have relied on these quirks you might need to update your code.
### Important Note
> Some quirks have been resolved that may cause changes for upgrading users who were expecting these behaviors
#### Form Validation
If you are using form validation, previous to `2.2.8` calling `is valid` would trigger UI updates. This behavior now **no longer triggers UI updates**, and will only return a `boolean` whether form is valid, as this was the intended functionality.
To trigger UI updates you can call `validate form`. Additional UI behaviors have been added as well, [see new documentation on programmatic validation](http://semantic-ui.com/behaviors/form.html#validating-programmatically)

#### Dropdown
Dropdown no longer automatically selects the currently selected value in a multi-select dropdown when you "alt-tab" or click out of a field. In most cases this is an unexpected behavior, even with `forceSelection`.
Dropdown no longer automatically selects the currently selected value in a multi-select dropdown when you "alt-tab" or click out of a field. In most cases this is confusing, although in most cases people expect a single select to preserve current value on tab, this is in most cases, not a normal expectation for a multi-select.
