# Bytebase 0.2.2 - Jul 26, 2021

## 🐞 Important Bug Fixes

* **MySQL connection leak** - In the previous version, when Bytebase does not properly release the connection after finishing connecting the MySQL instance, which will cause MySQL connection pool exhaustion.

## 🚀 New Features

* **External SQL console ([detailed guide](https://docs.bytebase.com/settings/external-sql-console))** - Allow user to configure an external SQL console like phpMyAdmin. If configured, Bytebase will surface the link to the console in the relevant database and table page
* **Issue list page** - Added a dedicated page to list issues. It supports to filter based on user/project/environment/issue status.
* **Project migration history tab** - The tab lists the migration history for each database under that project. For each database, Bytebase will list at most 5 most recent migration history, and user can click the database name to view the complete migration history.

* Added new 403, 404 page
