# Bytebase 0.6.0 - Sep 18, 2021

## 🚀 New Features

### Support [TiDB](https://pingcap.com/)

TiDB is an open-source, cloud-native, distributed SQL database for elastic scale and real-time analytics.

### Add task check to gate schema change

* This works similar as [GitHub merge request check](https://docs.github.com/en/github/collaborating-with-pull-requests/collaborating-on-repositories-with-code-quality-features/about-status-checks). The schema change only proceeds if all check pass.
* In this initial launch, we enforce 2 checks, db connection check and syntax check for the schema change task. We plan to add more checks like advanced SQL analyzer in the future.

## 🎄 Enhancement

* Show VCS push event info in the migration history detail page.
* Improve UX for configuring the instance connection.
* Improve UX for transferring database between projects.
* Create dedicated migration history tab for a particular database.
* Add baseline migration history record upon creating the database.

## 🎠 Community

* A special thanks to [TiDB's open source compatible MySQL parser](https://github.com/pingcap/parser). It saves us a lot of effort to implement our syntax checker.
* We have migrated changelog to our newsletter system as well. So in the future, new changelog will also be delivered to your email automatically.

## ⚙️ Install and Upgrade
