## `soda-core 4.0.5` - first public release of version 4&#x20;

<sup>28 January 2026</sup>\
This is the first public release of Soda Core version 4. This release introduces **Data Contracts as the default way to define data quality rules for tables**. The new approach offers a cleaner, more structured, and more maintainable way to define and manage data quality rules, based on community feedback and real-world usage.

{% hint style="danger" %}
This is a breaking change: Soda Core is moving from the checks language to a Data Contracts–based syntax.
{% endhint %}

Highlights of this release:

* Introduced support for **parsing**, **publishing** and (both locally and remotely) **verifying** data contracts.
* Introduced extended check diagnostics providing deeper visibility into the count and percentage of tested, passing, and failing rows.
* Introduced seamless flexibility to run Contracts via Core or the Soda Agent, with definitions stored either as external files or in Soda Cloud.
* Introduced "Missing", "Invalid", "Duplicate", "Aggregate", "Failed Rows", "Metric" checks in data contract.
* Introduced data contracts support for **multiple data sources**: Postgres, Snowflake, BigQuery, Databricks, Redshift, SQL Server, Fabric, Synapse, Athena, DuckDB (in memory).
* Introduced **new CLI** with a noun-verb structure and better integration with the Soda Cloud APIs (e.g. contract fetching based on a dataset identifier)
* Introduced support for `variables` in contracts, allowing you to parameterize contracts.
* Introduced support for **extending functionality** using plugins.
* Introduced **extensible check types**.
* Introduced concept and hooks for **contract verification result handlers**, allowing post processing of the contract verification results.

### Extensions

* Implemented the contract generation plugin.
* Implemented the diagnostics warehouse plugin.
* Implemented reconciliation checks.
* Implemented group-by checks.
* Implemented support for Oracle as a data source.
* Implemented support for Dremio as a data source.
* Implemented support for contract requests.
