# Bytebase 3.3.0 - Jan 16, 2025

> SOC 2

## 🛡️ SOC 2

We have obtained SOC 2 Type 1 certification. This certification validates our commitment to maintaining the highest standards of security, availability, and confidentiality in our database DevSecOps platform.

To request our SOC 2 Type 1 report, please [email us](mailto:sales@bytebase.com).

## 🔔 Notable Changes

* Simplify data masking, both UI and API are affected, check [docs](/security/data-masking/overview/) and [API examples](https://github.com/bytebase/example-database-security/tree/main/masking) for details. Behavior changes:
  * Global masking takes precedence over column masking. Previously, column masking takes precedence over global masking.
  * Eliminate masking levels. For both global masking and column masking, you now configure the associated semantic type. Semantic type in turn maps to the corresponding masking algorithm.

## 🚀 New Features

* Introduce **Release**, the new versioned database schema migration workflow. Create releases, which are versioned migration scripts bundled as a package to deploy, tell Bytebase which databases to deploy, and Bytebase will figure out which scripts to execute or skip if already executed.
* Support CosmosDB.
* Add project setting to allow users to self-approval their own issues.
* Schema Synchronization supports PostgreSQL materialized view.
* Preliminary support PostgreSQL 17.

## 🎄 Enhancements

* Copy query results by selected columns or rows in SQL Editor.
* Enhance Oracle data backup experience.
* Improve the loading time for the database anomalies page.
