# Bytebase 2.22.3 - Sep 05, 2024

> One-click rollback for PostgreSQL DML change

## 🚀 New Features

* [One-click rollback](/change-database/rollback-data-changes/#1-click-rollback) for PostgreSQL DML change.

## 🎄 Enhancements

* Enhance DML Backup and Restore Experience:
  * Guide users to create the `bbdataarchive` database. Prior backup cannot be enabled if this database doesn't exist.
  * Allow users to enable or disable the backup option after an issue is created.
  * For unsupported backup scenarios, an error will be reported when turning on the backup switch.
  * Support MySQL generated columns.
  * Bulk `UPDATE` statements to a single table will be backed up into a single table. Before, each `UPDATE` statement will be backed up into a separate table.
* Enhance SQL Editor sidebar:
  * Display column types and nullable information.
  * Show columns and dependent columns in views.
* Under the **Issued Created** tab, add an **All** sub-tab.
* Enable i18n support for auto-generated issue titles.
* Add a project setting to require manually entering issue titles instead of using Bytebase’s auto-generated titles.

## ⚙️ Install and Upgrade

* [Fresh install](/get-started/self-host/deploy-with-docker)

* [Upgrade](/get-started/self-host/upgrade)

*Before upgrading: 1) Back up the [metadata](https://www.bytebase.com/docs/administration/back-up-restore-metadata/) — in-place downgrade is not supported. 2) Do not run multiple containers on the same data directory. 3) Terraform users: upgrade Bytebase server first, then apply the new Terraform config.*
