# Changelog 1.0

> Validio 1.0 introduces a new user interface built around validators, recommendations, and backfilling.

**1.0.3**

2 June 2023

### Filter and sort segments

For each Validator, you can now *sort* and *filter* Segments in the [Validator details page](https://docs.validio.io/docs/validators/validator-details.md):

* **Sort** incidents either in ascending or descending order, or on muted Segments.
* **Filter** values in the Segments. In a sequence of 0 or more characters, you can add `_` to match any single character, or use `%` as wildcard.

### New metrics: `SUM` and `SUM_RATIO`

We've added new metrics for the following Validator types:

* [Numeric Validator](https://docs.validio.io/docs/validators/validator-types/numeric.md): `Sum`
* [Numeric Distribution](https://docs.validio.io/docs/validators/validator-types/numeric-distribution.md): `Sum ratio`

**1.0.2**

31 May 2023

### Improvements & fixes

* Added Boolean expression as [Filter type](https://docs.validio.io/docs/filters.md).

**1.0.0**

20 April 2023

### Say hello to our new UI!

We want to improve and streamline your experience, meaning that we've introduced, replaced, and removed some [key concepts](https://docs.validio.io/docs/introduction/key-concepts.md).

New Validio UI - Home Overview.

### Introducing: validators

Get familiar with our new key concept: [Validators](https://docs.validio.io/docs/validators.md)!

Configure a Validator to monitor data from your source and track a specific metric from one or more fields. Then, set up a threshold to catch incidents in the data validation.

#### Recommended validators

Validio can set up certain Validators to help you get started with your data monitoring. All you need to do is choose which Validator(s) you want to create from a [list of recommendations](https://docs.validio.io/docs/ai-features/validator-recommendations.md).

### Backfilling

Validio now supports [backfilling](https://docs.validio.io/docs/sources/managing-sources.md#backfilling-validators). Use the backfill option to load and view historical data in your validations.

### Improvements

* Credentials are now configured independently. This means that you can reuse your credentials for any source or destination that requires the same authentication.
* We have updated all our configuration wizards. Some of the highlights are:
  * [Windows](https://docs.validio.io/docs/windows.md) - required to calculate and validate metrics on a dataset in your source
  * [Segmentations](https://docs.validio.io/docs/segmentation.md) - subset your data from a source to validate metrics on.
  * [Notifications rules](https://docs.validio.io/docs/notifications.md) and [channels](https://docs.validio.io/docs/integrations/notification-channels.md) - group and send incidents to channels of your choice, such as Slack and Webhooks.
